Raindrops on the Door Latch

Prologue: The Rusted Copper Ring and the Erased Registry

At the foot of Mount Takagamine in northern Kyoto stands Amayadori, a century-old sukiya-zukuri estate steeped in cedar forests and endless seasonal rains.

The entire estate consists of a main hall, west wing guest quarters, and an east wing connected by a low, dim zigzagging corridor. At the far end of the east wing stands a heavy cypress lattice door kept shut year-round, surmounted by a faded vintage plaque and clamped shut at its center by a heavy forged-iron latch coated in peeling black lacquer and mottled verdigris. In the boarding registry maintained by the Kuga family, that courtyard was casually noted as machine room and old materials storage, never opened again to any lodging traveler or apprentice since a covert fire in the late Showa thirties.

Yet a house remembers. Whenever the rainy season arrives, mountain mists laden with heavy moisture roll down the ridges, and rainwater gathers along the chipped edges of roof tiles into thin streams, striking hollow reverberations upon mossy stepping stones. As the timber breathes moisture day and night, it lets out faint groans akin to aching joints, while past memories locked in darkness seep silently into the daily lives of every dweller, like moisture spreading along wallpaper seams.

Seventy-year-old matriarch Kuga Shino always sits in the tearoom overlooking the inner courtyard. A thick wool lap blanket covers her knees, her fingers idly turning a string of polished bodhi beads. Her grandson, twenty-six-year-old Kuga Ryo, crosses the corridor on creaking zelkova floorboards, cradling a binder crammed with maintenance schedules and utility bills jotted in black ink. Fifty years of silence and a deadlock neither dares unravel lie between the two generations.

Beneath the chilled iron of the east wing door latch lie two diametrically opposed voices: a young girl pressing herself against the door panel as flames draw near, shouting that opening the door brings peril; and a boy clawing frantically at the lattice amidst suffocating smoke, weeping and pleading for someone to open the gate. When the tempestuous night of May twenty-seventh descends, these two unyielding obsessions will tear open the very flesh of this ancestral house amidst lightning and torrential rain.

Chapter 1: Eaves Dripping and the Missing Page of Chronicles

On the early morning of May second, as late spring turned to early summer, the oppressive heaviness in the air drew near its critical threshold.

On the early morning of May second, Ryo stood before the cedar key cabinet beside the genkan entrance to conduct his routine monthly inventory. Brass keys hung from wooden pegs fitted with white labels, arranged from Main Hall One down to West Wing Six. Yet as his fingertip brushed past the vacant row at the bottom right, his heart skipped a sudden beat: the fifth hook of the third row was empty, beside which a faded pencil note read East-01, but the key itself was nowhere to be found.

Frowning, Ryo carried his clipboard into Shino's sitting room. The elderly matriarch was offering freshly clipped shikimi leaves to the Buddhist altar, while a thin plume of bitter herbal incense drifted from the burner.

"Grandmother, where is the master key to the east wing storeroom? There was an entry in the log when Uncle Gen did repairs last month, yet today the box is bare."

Shino did not even turn around. Placing the offering cup steadily upon a black lacquer tray, her voice remained utterly serene: "That chamber never required a key. The latch is bolted firmly from the outside, and what rests within is merely discarded furniture left by previous generations, nothing worthy of inventory. Ryo, oversee the rent from the west wing lodgers, and do not entertain thoughts that do not concern you."

"Yet the management regulations stipulate that every entrance must have duplicate backup keys for fire safety inspections..."

"Regulations are drafted by men, but the laws of this house were carved by the blood of the Kuga clan." Shino turned, her gaze as unfathomable as a dried well. "Close the book."

Ryo looked upon the elder's withered yet fiercely resolute face. His throat tightened, but he asked no more. Yet he did not close the ledger; instead, he drew a stark red underline beneath East-01.

On May third, rain arrived three days earlier than the meteorological forecast. Veteran carpenter Makabe Gen, clad in blue-grey work trousers stained with sawdust and cured tung oil, climbed an aluminum stepladder to reach the overhanging eaves on the north side of the east wing. Clamping three flat-headed brass nails between his lips, his calloused hand stroked a rafter that had turned heavily carbonized and sprouted greyish fungus.

"Ryo, pass up the spirit level," Gen called down toward the ground.

Looking up from beneath the ladder, Ryo asked, "Uncle Gen, how does it look?"

Gen spat out the nails into his palm and pressed his thumb hard against the seam between the rafter and the plaster wall. Decayed dark-brown wood crumbling into fine powder showered downward. "Worse than expected. The lead flashing on the roof valley cracked thirty years ago, only patched over with asphalt back then. Now all the rainwater seeps straight down this hidden crack into the interior wall of the east wing. Inside of a fortnight, the foot of the load-bearing pillars will rot through."

"Does it require stripping the tiles immediately for a complete overhaul?" Ryo asked, his voice strained with professional urgency.

Climbing down from the ladder, Gen brushed the grit from his palms and cast an ambivalent gaze at the cypress lattice door clamped shut by the iron latch. "I would tear it apart in a heartbeat. But your grandmother made a special point to lean on her cane and seek me out at the workshop, insisting I may only touch the outer eaves and forbidding me to lift a single tile over the interior. Ryo, timber does not lie. As deep as the water seeps, that is how vast the rotten flesh grows. If you keep hiding it, this house will crush itself sooner or later."

Gen did not share these words with the tenants dwelling across the corridor, but that evening he inscribed a single line in his repair journal: "East wing pillars exceed thirty-five percent moisture content; the physical structure teeters on the brink."

On May fourth, the archives of Dairin-ji Temple in town smelled of camphor and aging mothproof parchment. Kogure Maki, a Kyoto University history scholar engaged in organizing regional documents, wore white cotton gloves as she delicately turned the leaves of the Past Register of the Takagamine Kuga Clan. Drizzling rain tapped against the frosted window glass, leaving the chamber dimly lit.

Maki's finger halted abruptly at the page for Showa Thirty-Four. The hemp stitching on the book's spine bore unmistakable signs of having been severed by a razor; pages seven and eight had been cleanly torn away, leaving behind paper stubble that had long oxidized to yellow.

"Miss Kogure, have you located the mid-Showa record of name alterations following the fire?" the clerk inquired from behind the counter.

Maki swiftly covered the excised gap with her palm, smiling with composure. "Still searching. May I ask whether this past register was held in the Kuga family's private safekeeping before being entrusted to the temple?"

"Indeed. It was only in Showa Forty, following the demise of Lady Shino's father, that the whole collection was deposited with Dairin-ji."

Maki lowered her head, the ragged tear mirrored across the glass of her spectacles. Those two excised leaves coincided precisely with the ten-day span marking the passing of Kuga Sayo and the vanishing of lodger lad Tsujimura Touma. She took no photographs and lodged no inquiry with the temple staff; instead, she drew a sheet of translucent tracing paper from her briefcase, lightly rubbing the torn fiber edges with graphite. She knew well that in historiography, an absence can testify far more starkly than words.

At two-forty-five in the morning of May fifth, software engineer Aoyama Itsuki slid open Amayadori's wooden entrance door, dragging a body weighed down by sheer exhaustion. His eyes were bloodshot from endless hours before the display, tinnitus buzzing like the relentless whine of summer cicadas. As he padded along the dim west wing corridor toward the shared bathhouse, a faint scratching, like fingernails scraping across coarse sandpaper, pierced through his noise-canceling headphones.

Itsuki halted and removed his headphones. The sound originated from the corner of the east wing.

Behind the wooden lattice window there hung thick, cream-colored shoji paper. Cast in the eerie green glow of the corridor emergency lantern, a small, indistinct silhouette drifted slowly along the interior of the paper screen. It was by no means a cat, for the silhouette's shoulders hunched at an unnatural angle, resembling a small child straining on tiptoe to peer out.

Itsuki's pulse hammered violently, a bone-chilling dread racing down his spine. Holding his breath, he backed away two paces until his shoulder struck a timber pillar.

The following morning, Itsuki encountered Ryo in the communal kitchen warming milk on the stove. "Last night... was someone inside the east wing?" Itsuki held his black coffee, fingers trembling slightly.

Ryo's hand upon the pan handle paused for a split second, then answered in an even, almost indifferent voice: "Your eyes deceived you, Mr. Aoyama. The east wing has had no electricity for decades, and two aged crape myrtles stand outside the lattice; last night the gale was fierce, and branches cast swaying shadows against paper. You have worked far too many hours lately."

Itsuki stared into Ryo's placid eyes and pressed his lips into a pale line. He did not argue, but upon returning to his upstairs quarters, he opened his laptop, configured his professional stereo recorder for acoustic voice activation, and slipped it beneath the skirting board into the shadows of the corridor corner.

On May sixth, a black carbon-fiber tripod stood along Amayadori's engawa gallery. Independent documentary filmmaker Asahina Yuzuki held her mobile phone in a tense voice call with a Tokyo television producer, her tone hushed yet brimming with restless exasperation.

"...I know every online streaming platform is chasing abandoned ruin ghost stories, but the proposal for this piece was originally 'Spatial Ethics and Family Lineage of Kyoto's Traditional Sukiya Architecture,' not an occult paranormal hunt!"

The producer's frosty, impatient voice sounded over the line: "Yuzuki, art-house documentaries yield no viewer clicks. The backers demand sensations! That house saw deaths in the Showa era, and an east wing sealed for half a century is raw suspense material. If you cannot deliver an establishing cut from inside the east wing door by next week, the segment will be handed to team two for variety re-editing, and you can kiss your upfront production expenses goodbye."

Yuzuki gritted her teeth and slammed the end call button. Peering through the monitor at the deathly silent bolted door, the cypress grain within the frame radiated a suffocating leaden grey under the rain. Opening her notebook, she pressed her pen into the margin next to 'Structural Filming Permit' and scrawled six characters: 'Emergency Special Clause.' She knew she was sliding across ethical boundaries, but bank collection notices were already overflowing her Tokyo apartment mailbox.

On May seventh, cultural heritage conservator Shinohara Kaede sat kneeling in the workshop along the western courtyard. Holding an ultra-fine badger-hair brush, she was delicately cleansing a gable carving removed from the main hall. Her mobile phone buzzed in the corner of the workbench, the caller ID indicating the personnel head of the Nara National Research Institute for Cultural Properties.

"Shinohara, how fares your wrist neuritis? Next month the dehydration phase for unearthed lacquered artifacts from the Heijo Palace Site is scheduled ahead of time, and the evaluation committee hopes you might conclude your leave and rejoin us."

Kaede looked down at the flesh-toned elastic bandage bound around her right wrist. The neuralgia still struck like fine needles on rainy days, yet far more than physical ailments, she was captivated by the stagnant isolation of Amayadori.

"Chief, I wish to apply for a three-week extension on my leave. There is an assemblage of folk architectural specimens dating from the late Edo to early Showa periods here, preserved in states of extraordinary research value, and I hope to complete their structural survey."

Ending the call, Kaede lifted her head toward the rain-misted roof tiles of the opposite east wing. She had concealed the institute's recall request from Ryo. He had always viewed her as a delicate tenant recuperating from illness, but her sharp professional instincts told her that the decay afflicting this house was far more complex than ordinary rainwater and termites.

Chapter 2: Stress Marks on Wooden Frames and Microfilm

As time progressed into late May, the moisture in the air reached such saturation that even sheets of paper softened and curled.

On May eighth, in the basement microfilm viewing room of Kyoto City Central Library, folklore graduate student Nishizono Akira cranked the lever of the reader. As gears engaged, the film reel hissed faintly, projecting black-and-white reduced scans of the Kyoto Shimbun from July of Showa Thirty-Four onto the screen.

His eyes settled upon an unassuming brief report in the lower right corner of page four:

"'[House Fire in Takagamine, Kita Ward] Around eleven-forty on the night of the eleventh, a fire broke out in the auxiliary storehouse of the Kuga residence in Takagamine-cho, consuming approximately forty square meters. The owner's daughter (age nine) succumbed to asphyxiation during rescue efforts; the fire was suspected to have been caused by an overturned candle igniting cotton wool...'"

Pushing his glasses up his nose, Akira quickly turned to another document in his notebook, a copy of the Kuga Family Lineage deposited by Shino at Dairin-ji Temple. There it was stated unequivocally: "Eldest daughter Sayo passed away at home during the hour of the Dog (eight o'clock in the evening) on July eleventh, Showa Thirty-Four, from acute pneumonia."

The newspaper recorded the blaze at eleven-forty at night with death by smoke inhalation; the family registry recorded the time at eight in the evening with death by acute pneumonia. A four-hour discrepancy and completely contradictory causes of death could never be dismissed as mere clerical oversight. Akira hit the print button, and thermal paper emerged with a sharp chemical scent. Instead of taking the printout back to campus, he carefully folded it into quarters and concealed it inside the waterproof field bag he carried.

On May ninth, the black rotary dial telephone at the far end of the main hall gallery rang with sudden urgency. Shino walked slowly toward it and lifted the heavy receiver.

From the line came an aged, arrogant male voice thick with a Tanba accent, belonging to the current head of the Kuga clan, Shino's paternal cousin.

"Shino? Is it true you leased the west wing to rootless strangers? Scholars, film crews... what in the world are you thinking? Regarding the east wing, consider how much effort we expended back then to silence the police and Dairin-ji! If an outsider unearths so much as a single rotten plank that should never be seen, you will bring down the ancestral graves of the entire Kuga clan!"

Shino clutched the receiver so tightly that her knuckles whitened, yet her voice remained as rigid as frozen earth: "I maintain this residence; the clan has never contributed a single yen toward property taxes or annual preservation costs. The latch on the east wing has not been drawn in thirty years; no one enters."

"It had best be so. If that boy Ryo touches that door out of reckless ignorance, you surrender the stewardship of this estate without delay!"

The call was cut off abruptly, the dial tone droning inside the cold receiver. Standing behind a broad pillar in the corridor shadows, Ryo had witnessed Shino's ragged breaths and suppressed tremors with total clarity. He did not show himself, only pulling back his steps in silence. The family secret was an airtight web, inexorably dragging them all toward an abyss.

On the afternoon of May tenth, a thunderstorm unleashed torrential downpours. Carrying an electric torch and a wire brush, Makabe Gen slipped quietly before the east wing lattice door while the main hall stood deserted.

Crouching down, he leveled the beam of his torch parallel against the narrow gap on the inner side of the frame. From the outside, the iron crossbar seemed firmly locked in its hasp, but through decades of woodworking expertise Gen detected the abnormality at first glance: along the inner edge of the cypress jamb roughly one meter from the floor, the wood grain showed an unnatural crushed state, its fringes peeling back a layer of aged fiber tinged with dark brownish stains.

"What is this..." Gen inserted his fingers into the crevice to explore, the texture beneath his touch drawing a sharp gasp from his lungs.

These were reverse stress impacts caused by someone desperately thrusting from within or slamming heavy objects against the latch from the inside. Moreover, along a lower section of the jamb were seven or eight vertical claw marks spaced tightly together, half a centimeter deep, their hollows harboring traces of organic matter carbonized and flaked away by age.

The door had never been locked to prevent outsiders from intruding.

A marrow-chilling dread crawled up Gen's spine. For a fleeting second, he felt a powerful urge to photograph everything, hand the evidence to Ryo, or even summon the authorities. Yet he hesitated. As a craftsman whose forebears had repaired dwellings across Takagamine for generations, he understood all too well what it meant to flay open the festering wounds of an old landed family. Snapping off his torch, he told himself: "Tomorrow, once the rain lets up, I will inspect it thoroughly." That fateful hesitation allowed this vital physical proof to sink once more into darkness.

On May eleventh, a soft drizzle persisted. Kogure Maki stood alone changing her shoes at Amayadori's genkan, preparing to head for Dairin-ji Temple. From beyond the porch steps came the faint tapping of a cane against paving stones.

Clad in a faded navy kasuri kimono with hair completely white, an aged woman stood below the stone steps in the veil of rain, holding a worn black fabric umbrella. She appeared at least eighty-five years of age, her back sharply stooped.

Maki hurried down the steps: "Good day. Whom are you seeking? Lady Kuga is in the main hall..."

The elderly woman raised turbid, yellowing eyes to examine Maki, then looked past her shoulder toward the dim corridor weighted beneath heavy black tiles.

"Sayo... this marks the sixty-seventh year, does it not?" The elder's voice was cracked and hoarse, like two shingles scraping together.

Maki's heart leapt: "You knew Miss Kuga Sayo? Do you know what occurred back then?"

The old woman's lips twitched into a strange grimace between weeping and smiling. Trembling, she pointed a shriveled finger toward the east wing: "Pay no heed to the lies of that woman Shino. Sayo... Sayo died neither of sickness nor fire. That night, I was cutting grass on the back slope... I heard it. The door was bolted shut, yet within, more than one voice cried out for help..."

"You say more than one person? Who else was there? Was it Tsujimura Touma?" Maki stepped forward in earnest.

Yet as though strangled by an invisible specter, the old woman recoiled two steps in terror, her umbrella rim striking cedar boughs and shaking down a scatter of icy rainwater: "I have uttered nothing... I must say no more... the curse of the Kuga clan will hunt me down..."

With that, ignoring the slippery clay of the stone steps, the elder stumbled around and melted into the dense bamboo fog. Maki stood in the rain, droplets blurring her glasses. She did not pursue her, yet the words "the door was bolted shut" branded themselves into her mind like a searing iron.

On May twelfth, tension inside the ancestral house tightened further. At dawn, holding a handwritten room change notice, Ryo knocked directly upon Aoyama Itsuki's door.

"Mr. Aoyama, considering the potential hazard of foundation subsidence and falling tiles along the east corridor during the rainy season, starting today, please relocate your room from the eastern side of the west wing second floor to the westernmost storage partition." Ryo's tone brooked no refusal.

Rubbing his hollow, bloodshot eyes, Itsuki protested: "Mr. Kuga, that room enjoys the best natural light, and my servers and workstation wiring are completely set up. The westernmost room has windows that cannot even open and spans barely three tatami mats; this is forced eviction!"

Holding the binder against his chest, Ryo looked back coldly: "I am the superintendent of Amayadori. Safeguarding the lives of every resident in this building is my ultimate duty. If you do not accept this relocation, you are free to terminate your lease under Clause Seven and depart."

Itsuki glared at Ryo. In the depths of Ryo's gaze, he recognized a flicker of panic and compulsion to control; Ryo was not safeguarding him, Ryo was afraid. Ryo feared Itsuki's sleepless eyes in the dead of night, terrified of what he might glimpse down the corridors.

"Fine, I move," Itsuki sneered, turning around and slamming the sliding door shut. Once protection became a shackle of domination, trust evaporated entirely.

Late on the night of May thirteenth, Asahina Yuzuki mounted a miniature high-definition action camera upon a shadowed crossbeam at the turn of the east wing corridor.

Wrapped in matte black tape, the lens was aligned precisely toward the locked lattice door of the east wing. Officially, she had submitted a request to Ryo earlier that day for 'time-lapse photography to monitor nocturnal water leaks and termite activity,' obtaining his hurried verbal assent. Yet that application omitted any mention of infrared night vision, nor did it disclose that private audio of residents walking at night would also be preserved.

Sheltered within her quarters, Yuzuki watched the monitor on her tablet. Under black-and-white night vision, the east wing gallery appeared vast and menacing, each groove in the timber flooring resembling a petrified crawler. Donning monitoring headphones, she heard nothing save the unending rain beyond the window and the eerie thumps of aged timber contracting.

"This is not voyeurism; this is the search for truth," Yuzuki whispered to her reflection in the glass, yet her hands trembled uncontrollably.

Chapter 3: Two Sets of Nail Holes and Severed Audio Tape

In early June, the seasonal rains entered their most unrelenting phase, the entirety of Mount Takagamine steeped as if in a warm, suffocating marsh.

On May fourteenth, the workshop was infused with the slightly acidic aroma of turpentine and raw lacquer. Breaking all precedent, Shino took the initiative to enter Shinohara Kaede's studio, placing an oblong parcel wrapped in coarse hemp cloth upon the workbench.

"Miss Shinohara, this is a wooden tablet from the early Showa period, kept in the storehouse for many years and grown mildewed with damp. I understand you specialize in sterilizing antique timber; could you assist in consolidating its surface?" Shino's demeanor was outwardly courteous yet bristling with guarded vigilance.

Kaede unwrapped the hemp cloth to reveal a cypress plaque roughly thirty centimeters long and ten wide. The lower half exhibited distinct black scorch marks from fire, while the upper section, where characters had once been inscribed, had been deliberately ground away with sandpaper, leaving behind only the faint vestige of the character for 'soul.'

Slipping on gloves, Kaede turned on the shadowless magnifying lamp to scrutinize the wood. Suddenly, her tweezers paused at the apex of the tablet.

"Mrs. Kuga, where was this plaque originally mounted?" Kaede looked up to ask.

Shino's gaze drifted ever so slightly: "Merely an auxiliary hanging plaque from the old family altar room."

"Yet there are two completely distinct sets of nail apertures here," Kaede indicated the back of the plaque with a fine probe. "The first set consists of perforations from octagonal forged-iron square nails, ringed by deep oxidation spanning at least seventy years, with a spacing of six and a half centimeters. The second set belongs to round-headed galvanized nails from the mid-to-late Showa era, spaced eight centimeters apart; moreover, this second set was hammered in forcibly from behind only after the tablet had already suffered fire carbonization."

Shino's face drained of color in an instant. The coexistence of two sets of nail holes proved that after the blaze occurred, this tablet had been pried loose, altered, and affixed elsewhere entirely.

"...There is no need to make it too pristine; merely halt the mold from spreading." Clatching the cloth abruptly before the antifungal agent had even dried, Shino wrapped the tablet hastily and hurried out the door. Watching her fleeing figure, Kaede's analytical gaze turned colder.

On May thirteenth, an audit notification appeared within the consultation system of the Kyoto Prefectural Archives. Nishizono Akira officially submitted a request under the title 'Postwar Urban Disaster Prevention in Kita Ward and Case Studies of Specialized Residential Fires' to inspect all fire brigade dispatch reports and police autopsy files concerning the Takagamine area between Showa Thirty-Four and Thirty-Six.

This was an entirely open, real-name application. Akira had assumed it would be an ordinary academic requisition, yet within three hours, a librarian telephoned him directly:

"Mr. Nishizono, the archives you requested are presently classified under 'Restricted Public Access.' Vault records show that ten years ago, legal representatives of the Kuga clan executed a family privacy covenant, requiring written authorization from the current head of the Kuga house for any third-party disclosure."

Clasping his phone in the hallway, Akira felt his heart sink to the depths. He realized his academic inquiry had startled the snake in the grass. The Kuga clan's protective network was vastly more pervasive than anticipated, and now that net was tightening in response to his every move.

At three-twelve in the morning of May sixteenth, rain poured relentlessly, dense drops slamming into the galvanized eaves gutter of the east wing with the clattering roar of a machine gun.

Aoyama Itsuki jolted awake from a nightmare. Bathed in cold sweat, he sat upright, snatched the headphones from his desk, and jacked them into the voice recorder hidden beneath the skirting board.

A wash of raucous ambient rain hiss filled the earpieces. Patiently, Itsuki dragged the waveform timeline. Suddenly, at the timestamp of two-fifty-eight, an anomalous spike rose starkly across the waveform.

Itsuki adjusted the output volume to maximum.

Amidst the rain, there was distinctly mingled the dragging of steps; not the shuffle of slippers, but the sticky, moist tread of bare feet upon damp floorboards: squelch, squelch, squelch.

The footsteps came to a halt right before the lattice door of the east wing.

Immediately after, there drifted into the headset a whisper so faint yet as intimate as breath puffed directly against the microphone membrane:

"...Itsuki... it is so dark... Itsuki..."

Itsuki was struck as if by lightning, the headphones nearly slipping from his grasp.

Itsuki-kun, that was the private pet name spoken only by elders in his ancestral home before he was six years old and before his mother passed away! Since entering boarding school at twelve, not a single soul in this world had addressed him by that name!

Paralyzing horror clamped around Itsuki's heart like an icy talon. His breath turned ragged, as though suffocating. Staring at the sinister waveform in the software, his trembling hand gripped the mouse, selected the four-second segment containing his childhood name, and struck the Delete key with all his might.

He purged the four most crucial seconds. He dreaded that were this recording overheard, others would brand him a lunatic; but even more, he feared that the phantoms haunting this ancestral home had truly peered into the deepest frailties of his soul.

On May seventeenth, the most ferocious quarrel since their arrival at Amayadori erupted between Ryo and Shino in the main living room.

"We must suspend operations immediately and vacate every tenant!" Ryo slammed Gen's structural inspection memorandum onto the low tea table, causing the teacups to clatter and spill across the runner. "Uncle Gen warns that moisture in the east wing load-bearing pillars has exceeded all limits; if a major typhoon strikes, the entire gallery risks total collapse! Furthermore, strange sounds prowl the corridor every night, driving everyone toward nervous breakdown. If this continues, lives will be lost!"

Seated upright upon her cushion with an ashen countenance, Shino's eyes burned with an almost fanatical fury: "Vacate them? If you drive them away, whence will come next month's preservation funds? Whence will come the three million yen in annual municipal property taxes? Ryo, how do you imagine this estate survived these past sixty years? On this meager rent, and on my aged dignity bowed low before our kin! So long as breath remains in my chest, Amayadori shall not shut its gates!"

"Are you safeguarding this house, or are you shielding the sordid secrets you dare not let the world see?!" Ryo lost all restraint, his shout resounding through the room.

Smack! A resounding slap struck across Ryo's cheek.

The parlor plunged into tomb-like silence. Shino's hand shook violently in the air, her eyes brimming with tears and bitter resentment: "Ungrateful wretch... you have no inkling of what would become of our Kuga clan if that door were breached..."

Behind the sliding door seam of the adjacent chamber, Maki and Akira exchanged pale glances. They had overheard every syllable, the sacred veneer of the ancestral house shredded beyond repair.

On May eighteenth, an unstamped and unsigned white envelope appeared inside Dairin-ji Temple's mail slot. Pushed directly through the temple office door, it bore only the inscription: 'To Miss Kogure Maki.'

Maki slit open the envelope to find a single leaf of squared manuscript paper torn from a student notebook, upon which two lines were inscribed in shaky blue ballpoint:

"'Sayo was bolted inside because she went to fetch medicine for Touma. The blaze was no accident. The rescuer became a sacrificial lamb, while the true deserters lived on as a distinguished lineage.'"

Maki's pupils contracted sharply.

Touma! The letter explicitly named Tsujimura Touma!

In official accounts to date, Touma was merely a distant cousin who had 'run away from home' prior to the disaster; yet this anonymous missive directly tied Sayo's death to Touma's fate. Who penned this note? Was it the enigmatic old woman who had materialized at Amayadori's entrance? Or an observer who had silently watched the house all along? Maki pressed the slip under the deepest layer of her notebook. She knew that the outline of a homicide or abandonment obscured for half a century was steadily sharpening into view.

On May nineteenth, heated altercations resounded along the courtyard gallery.

Makabe Gen seized the pan-head of Asahina Yuzuki's tripod, blue veins bulging across his temple: "How many times must I tell you to clear this junk from the east wing entrance! Do you not realize that rubber feet resting on sunken corridor floorboards will accelerate tenon fracture?!"

Yuzuki did not yield an inch, guarding her camera fiercely: "Mr. Makabe, I possess a valid filming permit endorsed by Mr. Kuga! This corridor is common space, and I have every right to position my gear here! If you damage my lens, can you afford the compensation?!"

Gen let out a harsh sneer, pointing toward the bolted cypress door: "You fancy yourself making art? You are merely sucking blood from this house! Young lady, once certain doors are breached, they must be paid for in human lives!"

Ryo rushed over to pry the two apart. Yet this clash planted deeper seeds of mutual suspicion in every heart. Ryo began suspecting Yuzuki of concealing her true documentary objectives, while Yuzuki grew convinced that Gen and the Kuga family were colluding to bar the public from ever uncovering the truth.

Chapter 4: Scorched Tablet Behind the Altar and Eleven Silent Minutes

By mid-June, the air inside Amayadori grew permeated with a cloying sweetness akin to decaying timber and fermented vintage silks.

On May twentieth, Shinohara Kaede stood by the window of her chamber and placed a phone call to the personnel chief of the Nara Institute.

"Chief, it is I. I wish to submit a formal request for unpaid sabbatical leave until the conclusion of the rainy season."

The chief's bewildered query came over the line: "Shinohara, does your wrist injury genuinely necessitate so lengthy a rest? The damp climate of Takagamine offers zero benefit to neuralgia."

Looking upon the hand-drawn rubbings of the tablet's nail holes resting on the table, Kaede's voice remained exceptionally poised: "Chief, it is not for my injury. I have encountered here an exceedingly rare composite structure uniting late Edo preservative lacquer and Showa fire-carbonized layers. This is no ordinary folk residential timber; it likely pertains to an unrecorded postwar private ritual artifact. I must document it to completion."

The instant she lowered the receiver, Kaede knew she had crossed the boundary. She was no longer a detached observer convalescing in peace; the secrets of this ancient manor drew her like a lodestone, dragging her headlong into this uncharted tempest.

On May twenty-first, in an internal commemorative publication issued during the Showa thirties by the Kyoto Prefectural Police Veterans Association, Nishizono Akira unearthed a yellowed facsimile of the preliminary fire investigation dossier.

Within this report, never made public, the personnel present at the fire ground were itemized in meticulous detail. Akira ran a magnifying lens word by word across the long roster: Kuga Shino, Kuga Zenzaburo, Kuga Sayo...

Yet across three full pages of records, the name Tsujimura Touma was entirely absent.

Moreover, under the column for 'Permanent Residents of the Afflicted Household,' the digit had been altered with red fountain-pen ink, amended from an initial 'five' to 'four,' stamped beside by an exceedingly faint private seal.

Touma's very existence had been excised deliberately from the earliest official disaster tallies. Had he never been recorded among the resident population, he could never be legally logged as 'deceased' or 'missing' following the catastrophe. In the realm of law and administrative records, Tsujimura Touma was rendered an absolute ghost. A chill swept down Akira's back; this was no longer an isolated familial concealment, but a grave suspicion of criminal collusion aided by public authorities.

At daybreak on May twenty-second, as the sky broke into murky grey, the faint friction of timber panels sounded from within the main altar hall.

Kneeling before the massive black-lacquered Buddhist shrine, Shino strained to slide open a concealed panel in the plinth. Cupping with both hands the scorched wooden tablet she had snatched back from Kaede, her eyes brimmed with terror and despair.

"Sayo... Touma... bear me no malice..." Shino's haggard visage appeared ghastly beneath the flickering glow of the eternal vigil oil lamp. She thrust the tablet deep into the bottommost cavity of the altar, then shoved the hidden panel flush back into place.

She believed it had all occurred without a trace. Yet when Ryo entered the shrine that afternoon to replenish lamp oil, his eyes caught a tiny fresh scratch along the gold-leaf trim of the plinth. Crouching down, Ryo brushed his finger over the abrasion, his expression hardening into ice. His grandmother was concealing something, and what she hid had power enough to shatter the very bedrock of the Kuga clan.

On May twenty-third, Amayadori was engulfed by an extraordinary tempest, corridor lattices shuddering violently against the howling wind.

At six in the morning, Aoyama Itsuki stepped from his door heading for the shared washroom. The moment his feet paused at the entrance to the east gallery, his entire body froze.

Across the pristine zelkova timber, trailing from beneath the seam of the east wing lattice door, stretched a chain of sodden footprints.

The prints were small, measuring roughly twenty centimeters in length, resembling the gait of a seven- or eight-year-old child. Laden with the dark, decomposed humus of mountain woods, the prints marched step by step straight down the gallery toward the main altar hall, only to vanish abruptly in mid-hall, leaving no sign of return.

Itsuki let slip a stifled shriek.

Within two minutes, Ryo and Makabe Gen arrived on the scene together.

With an ashen face, Ryo instantly seized a mop to wipe the floor: "Rainwater has flooded backward, or perhaps a mountain tanuki strayed in..."

"Keep away!" Gen shoved Ryo's hand aside roughly. Kneeling down, Gen pulled a steel tape measure from his work pocket to inspect the texture and weight distribution of the muddy prints.

"This is no wild beast," Gen's tone dropped like lead. "These are human prints. What is more... inspect the wear and balance between ball and heel; this is the distinct imprint of natural straw zori woven in the early Showa era. No one on the market wears footwear like this today."

Standing to the side, Itsuki shuddered violently: "I told you... I told you there was something within! None of you believed me!"

Ryo stood between the two men, squeezing the mop handle until his fingers bent against the grain. Gen's physical appraisal and Itsuki's hysterical testimony struck Ryo's mind like twin hammer blows. The regulatory order upon which he maintained stability began disintegrating before his eyes.

In the dead of night on May twenty-fourth, Kogure Maki knocked upon Nishizono Akira's door.

Carrying the tracing of the torn page from Dairin-ji, Maki entered Akira's quarters. Akira poured her a cup of warm barley tea, and the two took seats before the compact writing desk.

"Nishizono, I require your assistance," Maki spread the tracing paper upon the desk. "The two pages torn from the Dairin-ji register correspond precisely to the fire you are investigating. However, I cannot formally requisition forensic handwriting or paper spectral analysis in the name of an academic institute; doing so would ruin Dairin-ji's repute and see me expelled from the document committee."

Pushing up his spectacles, a flicker of academic zeal lit Akira's eyes: "I have a route. The Papermaking History Institute at Hiroshima University possesses a fiber spectroscopy comparative database; with merely trace edge rubbings, they can ascertain the chemical components and manufacturing era of the paper. However, Miss Kogure, in exchange, you must disclose in full all oral testimonies you have obtained within the temple."

Maki inhaled deeply: "Agreed. But this must remain utterly shielded from Lady Kuga and Ryo."

An alliance of researchers was forged within the shadows of the study, and the price of this pact was to plunge Amayadori into yet deeper estrangement and distrust.

On May twenty-fifth, Asahina Yuzuki received an ultimatum from her Tokyo producer.

"I expect a rough-cut preview on my desk by next Monday, or legal will issue a formal summons demanding two million yen in liquidated damages."

Locking herself in her quarters and pulling the curtains, Yuzuki scrutinized the footage captured by the fixed camera frame by frame. Abruptly, her fingers froze over the trackpad.

At eleven-forty at night on the previous day, May twenty-fourth, precisely the hour when the ancient conflagration erupted, the timestamp on the screen jittered abruptly. What followed was a total void of pure static blackness lasting eleven minutes: no visual, no sound, even the ambient patter of rain along the corridor completely swallowed. Only at eleven-fifty-one and fifteen seconds did the feed abruptly normalize, the east wing lattice door remaining firmly bolted as though nothing had occurred.

Yuzuki pulled up the device system logs. The logs verified that during those eleven minutes, sensor and microphone power remained nominal, battery draw showed zero fluctuation, and there had occurred neither outage nor reboot event.

It was no equipment defect. It was eleven minutes of an 'absolute vacuum' physically erased from existence.

At that instant, Ryo knocked from outside: "Miss Asahina, please open. Routine fire and safety inspection."

With blinding speed, Yuzuki pulled the SD card and slipped it into her inner pocket. When she opened the door to face Ryo's watchful, scrutinizing visage, her tone was terrifyingly composed: "Mr. Kuga, the camera has failed; I was just preparing to dismount it and ship it back to Tokyo for service." The two looked into each other's eyes, fully aware that falsehood had become the sole currency circulating within this house.

Chapter 5: Fresh Scratches on the Latch and Forbidden Names

On the afternoon of May twenty-sixth, the most violent frontal system of the rainy season gathered over the Pacific Ocean, its gale-force core designated Super Typhoon Number Six roaring toward the Kinki region.

As night fell on May twenty-sixth, Yuzuki sat in her room employing professional sound-editing suites in an attempt to reconstruct that eleven-minute void.

She boosted the gain by a full forty-eight decibels and layered multiple noise-reduction filters. From the depths of deafening white floor noise, an exceedingly faint, heartbreakingly rhythmic percussion slowly emerged.

Thump... thump... thump...

It was neither thunder nor rain. It was the impact of a solid weight striking heavy timber, slow and ponderous, repeating every three and a half seconds. Yuzuki's fingers stiffened over the keys. She neither confessed to Ryo nor transmitted the audio to the Tokyo production team. This excised void became a crushing ethical abyss, holding her fast within its gravity. If published, the documentary would become a sensationalist viral sensation; if concealed, she would bear the weight of this phantom plea for salvation for the remainder of her days.

On May twenty-seventh, Nishizono Akira received an express courier delivery from Hiroshima University containing the spectral analysis summary.

The analysis confirmed that the sulfate fillers within the fibers of the excised leaves from the Dairin-ji past register were identical to modern woodfree paper popularized in Japan only after Showa Thirty-Six.

In other words, those two pages were by no means torn out at the time of the fire in Showa Thirty-Four. Two years after the conflagration, someone armed with a razor blade had meticulously sliced out the original leaves bearing the truth, substituting forged entries until, years later, even those falsifications were ripped away by guilty hands.

Carrying the report facsimile, Akira entered the communal dining hall. At the dinner hour, tenants ate their ochazuke in silence. Shino sat at the head of the table, regarding each person with freezing detachment. Hands buried in his pockets, Akira crumpled the paper tightly, palms slick with cold perspiration. Several times he parted his lips to demand an explanation, but seeing Maki's beseeching glance beside him and Ryo's tense, defensive expression, he choked the words back. The truth lay beneath the table, yet none dared overturn it.

At dusk on May twenty-eighth, howling gusts began battering the cedar groves of Mount Takagamine, the rain escalating into a violent torrent.

Torch in hand, Makabe Gen arrived once again before the lattice door of the east wing. This time, his gaze was captivated by the iron hasp to the right of the crossbar.

Across the rusted forged-iron bar appeared two silver-white gouges gleaming with raw metallic sheen. The furrows were deep, their metal burrs not yet oxidized by the surrounding humidity.

Gen pressed his palm against the iron latch. The iron was icy, yet beneath the chill, a faint tremor pulsed through the interior of the timber door, as though a weak draft were inhaling outward along the frame.

Locating Ryo inspecting the storehouse, Gen dragged him roughly around the corridor corner.

"Ryo, we can delay no longer," Gen's voice was hoarse and stern. "Fresh gouges mark the latch, the internal timber framing is warping, and there may even be a living soul within, or... something fighting to burst out. Tonight we must weld the bar with steel cables, or seal the east wing entirely and evacuate everyone!"

Ryo's face shifted between pallor and agitation: "Uncle Gen, the typhoon makes landfall tonight; where could we evacuate everyone now? And if we seal the east wing with such fanfare, Grandmother will lose her mind! If the press catches wind..."

"Do you care more for the family's reputation, or for human lives?!" Gen snarled in fury.

Their heated clash was overheard word for word by Yuzuki across the hall. Concealed behind a sliding partition, Yuzuki quietly pressed the record button of her portable microphone. A question of physical safety had morphed into a struggle for authority, each individual staking their chips upon survival.

At four in the afternoon on May twenty-ninth, the heavens turned as dark as midnight. Inside Amayadori's communal kitchen, only water droplets striking the stainless-steel sink broke the silence.

Clad in a slicker, Aoyama Itsuki was carrying his final crate of source code journals and hard drives toward the entrance. He had summoned a taxi, resolved to flee this madhouse.

As he returned to the kitchen to fetch his travel mug, from the deserted pantry behind him there resonated an unmistakable, crystal-clear voice:

"...Itsuki... why will you not open the door... it burns so badly..."

That voice was no longer weak, nor was it drowned in storm. It was crisp, youthful, choked with sobs, a young girl's cry so near it seemed blown directly against the nape of his neck!

Itsuki released a bloodcurdling scream, dropping the cardboard box to the floor with a crash, hard drives and manuscripts scattering everywhere. Scrambling on all fours toward the entrance, he did not even pause to gather his invaluable equipment.

Ryo bolted from the office in an attempt to restrain him: "Mr. Aoyama! A severe typhoon warning is in effect outside; the mountain road could collapse at any minute, you cannot leave now!"

"Unhand me! You madman! Your whole family is completely insane!" Itsuki tore his arm violently from Ryo's grip, shoved open Amayadori's entrance door, and plunged headlong into the stormy pitch-black night. The estate lost its primary acoustic witness, and the final veil of tranquil illusion was torn away.

On May thirtieth, the typhoon eye was steadily drawing toward the Kinki area.

Rummaging through forgotten closets, Ryo at last unearthed from the bottom of his late grandfather's vintage stationery casket an antique brass key roughly fifteen centimeters long, devoid of label or serial mark.

Key in hand, Ryo thrust open Shino's bedchamber door with burning indignance.

"This key opens the concealed inner door of the east wing, does it not?!" Ryo hurled the key violently onto the tatami before Shino.

Shino sat within the gloom, lamps left unlit. Outside, fierce gusts rattled the shoji panes incessantly.

The matriarch raised her gaze slowly to the tarnished brass key, a tragic, merciless smile curling the corners of her mouth: "That was never intended for your hands. Ryo, whom do you imagine yourself to be? You are merely a waif taken in by the Kuga family. The rightful masters of this estate perished within that very chamber decades ago."

As if struck by lightning, Ryo froze where he stood: "You... what did you say?"

"Be gone. Take your account ledgers and depart Amayadori," Shino closed her eyes in icy detachment. "The sins of this estate shall accompany me alone into the grave."

At this moment, all bonds of blood and ownership among the living were shattered. The east wing door ceased being an architectural dilemma of timber maintenance and transformed into an abyss devouring the very ethics of the lineage.

On the afternoon of May thirty-first, the heavens opened in torrents, broad daylight plunged into night.

Braving the gale across the courtyard, Shinohara Kaede approached the exterior wall of the east wing. To her horror, along the earthen wall once finished in white lime, a monstrous, pitch-black water stain was creeping upward from the stone plinth. The stain sprawled in an uncanny shape, resembling countless hands fighting to burst through the plaster, clawing madly at the lime.

At that exact moment, the monitor in Yuzuki's chamber emitted a shrill beep; the equipment, silent following power loss, booted spontaneously upon its reserve battery.

Across the screen, the bolted cypress door of the east wing trembled visibly.

Above the lintel, dark, ashen droplets were dripping down along the iron latch.

Kaede witnessed the collapse of structural integrity, Yuzuki recorded inexplicable anomalies, Maki held proof of historical fabrication, Akira possessed evidence of bureaucratic cover-up, Gen clutched the physical proof of reverse impact on the latch, and Ryo disintegrated under the despair of family betrayal.

The tempest arrived in all its fury, Amayadori teetering amidst torrential rain and wind like a solitary skiff cast upon mountainous waves.

Epilogue: Damp Air Before the Thunderstorm and Two Overlapping Cries

The truth behind the great fire on the late night of July eleventh, Showa Thirty-Four, was never something an ordinary incident report could hold.

That night, nine-year-old Kuga Sayo secretly took the family keys and slipped into the east wing, then used as a vault for the clan's illicit postwar ledgers. She had not ventured there for play, but to deliver fever medicine and fresh water to her distant cousin Tsujimura Touma, who was confined within by Shino while burning with illness. Yet when a candle accidentally set ablaze the towering stacks of old account books, Shino's panic-stricken instinct was not to save lives, but the terrifying prospect of exposure for the tax evasion and illegitimate lineage hidden within that room.

Amidst billowing smoke, Shino thrust the heavy forged-iron crossbar into the latch socket from outside with trembling hands.

She bolted the door completely.

On the inner side of the door, ravenous flames raged. Sayo pressed her tender body against the scorching cypress panels with all her might. She heard frantic footsteps outside and the clamor of firefighters, yet behind her she saw collapsing rafters engulfed in hellish heat. With her final ounce of strength, she screamed through the crevice:

"Do not open the door! The fire is coming! Do not open the door...!"

And from deep within the inferno behind her, Touma, his eyes bleeding from suffocating smoke and clutching that charred wooden plaque, clawed madly at the doorframe and lattices with a desperate wail:

"Help me! Open the door! Let me out! I am inside...!"

Sixty-seven years passed.

The wills of two children, two irreconcilable longings, were welded forever to that very door by the conflagration and the unyielding iron latch.

Sayo's spirit transformed into a shield of protection and severance, desperate to shield innocent souls outside from being devoured by the abyss, so that with every spectral manifestation, she frantically broadcast the chilling dread of never opening the gate;

While Touma's resentment hardened into an eternal instinct for survival, languishing through more than half a century in dark purgatory, pounding day and night upon the latch and weeping to be rescued.

Outside the latch stood Tsujimura Ryo, having just learned the bitter truth of his origins.

For twenty-six years, he had tended this crumbling ancestral residence as a presumed grandson of the Kuga clan. Only tonight, holding the blackened brass key left by his grandfather and witnessing Shino's freezing, resentful smile, was the facade of bloodline utterly torn away. He was no descendant of the Kuga, but the surviving orphan of the Tsujimura lineage erased from official history in that fire. Shino took him in partly from deep-seated dread of vengeance from the restless dead, and partly to keep the last pulse of Tsujimura blood forever imprisoned under her gaze.

Leaning against a chilled, damp timber pillar along the gallery, Ryo felt his chest torn by overwhelming grief. In his ears, Sayo's voice from within was an act of sacrifice and protection for the living outside; while Touma's ceaseless scratching was the desperate bid for life of a boy from his own bloodline trapped in darkness. Across the latch, one side was sanctuary and the other a chasm, two streams of memory spanning sixty-seven years converging completely tonight.

Late into the night of May thirty-first, the tempest at last reached its terrifying zenith. Roaring winds swept down from the crest of Takagamine carrying torrents of rain, slamming violently against every loosened black roof tile. Lightning tore through the pitch-black sky like a silver blade, and with a deafening crash of thunder, the main circuit breaker of Amayadori tripped instantly, extinguishing every light.

The ancient house plunged into an ink-black darkness where one could not see one's own hand, engulfed in suffocating dampness.

From deep inside the east wing came the sharp screech of splintering timber fibers, followed immediately by a muffled metallic crack.

The black lacquer upon the crossbar flaked away completely. The rusted iron ring swung violently in the howling crosswind.

Outside the door, those holding the pieced-together fragments of cruel truth held their breath in the lightning flashes, none daring to disturb this fragile equilibrium; inside, awakened in full by the deluge and thunder, two intertwined voices cried out after sixty-seven years of torment.

Just as this century-old residence stood poised to be swallowed whole by its crushing burdens, from below the stone steps of the front courtyard came the sound of steady, deliberate footsteps cutting through the thunderstorm. It was a traveler drawn here by the ancient patter of rain and the threads of karma.

A solitary figure stepped onto the wooden genkan threshold in the gale, gently knocking upon the rusted copper ring of Amayadori's front gate.

Amidst the silent expanse of the manor, the raindrops striking the door latch remained as crisp as ever. The ancient residence held its breath under the storm, awaiting the destined one who would push open the heavy door and quiet the sixty-seven years of sorrow crying from both sides of the latch.
