Chapter Text
The late Sendai sun was a bruising purple over the rooftops, but the heat still clung to the asphalt, thick and suffocating. Wasuke walked with a heavy, rhythmic limp, his gut churning. It was a physical sickness he hadn’t felt since Jin first brought her home. That feeling of something wrong.
Indiscernible as to what exactly the problem was, but Wasuke’s gut had never been wrong.
Something was wrong.
He’d been a fool. He knew it every time he looked at the quiet, dusty corners of his house. He’d pushed Jin too hard, demanded perfection, and offered nothing but a paycheck and a stern face in return. He hadn't doted. He hadn't been there. And when Jin finally found someone who made him smile, Wasuke had been too late to tell him that the woman’s soul felt like stagnant water. Wrong.
Even before the accident, Kaori had been off. There was an energy radiating from her that never failed to put Wasuke in a state of unease. It was a pressure, a sense of being cornered in a space too small to breathe, an ancient instinct shouting that he was being hunted by something he had already met once before. He looked at her and felt the echo of teeth.
Kaori was a kind girl when she had been introduced to him. Guild weighed down on Wasuke as he struggled to interact with his daughter-in-law, not being able to sequester the suffocating sense of disgust he felt around her.
Then came the accident. She had been declared dead. Cold, gone, finished. Yet, a mere month later, she was sitting back in the comfort of the Itadori household like she’d just been out for groceries.
Something had fundamentally changed within her. The energy radiating off her wasn't life; it was a physical weight. A slow, creeping rot that turned the air in the room sour. And Jin, his bespectacled and blind son, had just wept and called it a miracle.
Freak, Wasuke thought, the word bitter as bile. It was more likely Jin had chosen to be blind, willing to trade his soul for a stitched-up ghost.
"Jiichan! You’re late!"
Wasuke blinked, the memory of his son’s face fading as he reached the gate of the small neighborhood house. Sato-san was standing there, wiping her hands on her apron. She was a good woman, one of the few who didn't mind the meager pay Wasuke scraped together from his dwindling labor shifts.
"Sorry, Sato-san. The legs aren't what they used to be," Wasuke grunted.
"Oh, don't you worry about it. Yuuji-kun was a treasure today," she smiled, stepping aside as a blur of pink hair scrambled out the door. "He’s so strong, Itadori-san. He helped me move the heavy planters in the garden. He’s got his grandfather’s spirit, that one."
Wasuke looked down. Yuuji beamed up at him, a radiant, energetic force of nature. He was the image of Jin. The same dimpled, kind smile, the lightly-freckled nose. Not to mention the hair - an Itadori classic. But the eyes... those were Kaori’s eyes. Perceptive, wide eyes, a distinctive amber.
"Come on, brat. Let's go," Wasuke said, his voice gruff to hide the way his heart squeezed.
"Bye, Sato-obasan!" Yuuji waved, his small hand sliding into Wasuke’s.
As they walked, Yuuji’s voice filled the quiet street, a constant stream of toddler logic and excitement. Wasuke watched him out of the corner of his eye. He tried to tell himself the dread in his stomach was just a side effect of his new medication. A bad reaction. Nothing more.
"And then we had rice balls in the back," Yuuji said, swinging Wasuke’s hand. "And a lady came to the fence."
Wasuke’s thumb stilled against the boy's knuckles. "A lady?"
"Yeah. She was pretty. She had a real soft voice," Yuuji chirped, looking up. "She knew my name, Jiichan. She said I was growing up big."
Wasuke stopped. The sound of a distant cicada seemed to roar in his ears. "...Did she now? What did she look like, Yuuji?"
Yuuji pouted, thinking hard. "She had a funny mark. Like a long scratch right across her head. Here." He took his hand out of Wasuke’s and drew a line across his own forehead.
The world seemed to tilt. The blood in Wasuke's veins turned to ice. It was her. The bitch was back from the grave again, or perhaps she’d never left.
"Yuuji," Wasuke said, his voice dropping into a sharp, low register that made the boy’s smile vanish. "Listen to me. If you see that woman again, you don't say a word. You don't look at her. You run inside and find Sato-san. Do you hear me?"
"But she was nice–"
"I don't care!" Wasuke snapped, his hand trembling. He saw Yuuji’s eyes well up and immediately felt a fresh wave of guilt, but the terror was louder. "She’s a stranger, Yuuji. A dangerous one. You stay away from any woman with a scar like that. Always."
Before the boy could respond, Wasuke reached down and hauled him up. His back screamed in protest, his old muscles straining under the boy's weight, but he didn't care. He tucked Yuuji’s head into his shoulder, shielding him, and began to half-walk, half-run toward their home.
He didn't look back. He just stared at the front door of their apartment, praying the locks would be enough to keep the ghost out.
The stairs to the apartment felt like a mountain. Each step sent a jagged bolt of lightning from Wasuke’s knees to his lower back, but he didn't dare set the boy down. He clutched Yuuji with a white-knuckled grip, his heart a frantic drum against his ribs. When they finally reached the door, he fumbled the keys, his hands shaking so violently they rattled against the lock.
Inside, the apartment was silent. It was small, cramped, and smelled of the cedarwood incense Wasuke used to mask the scent of his own aging.
He locked the deadbolt, slid the chain into place, and leaned his forehead against the wood, gasping for air.
"Jiichan? You’re squishing me," Yuuji mumbled, squirming in his arms.
Wasuke let out a ragged breath and set him down. "Go play, brat. Stay away from the windows."
That night, sleep came like a heavy, suffocating blanket, bringing with it the ghosts Wasuke spent his waking hours outrunning.
1999.
Jin was seventeen, standing in the middle of this same cramped living room, his face flushed with the kind of indignant rage only a teenager could muster. Behind him stood a girl. Kaori.
She wasn't some polished monster yet; she was just a girl in a school uniform, looking small and deeply uncomfortable. She was holding a box of store-bought sweets, her knuckles white.
"I am sick of this!" Wasuke roared, his voice echoing off the thin walls. "You have entrance exams in six months, Jin! Look at your scores! You’re throwing your life away for what? To play house?"
"I’m not playing house! I’m happy!" Jin yelled back, his chest heaving. "For once in this miserable, quiet house, I’m actually happy! Why is that such a problem for you?"
"Because you're an idiot!" Wasuke pointed a trembling finger at Kaori. "She’s a distraction! You think life is easy? You think love pays the rent? Get her out of here and get your head in a book!"
Kaori flinched as if he’d slapped her. Her eyes welled up, and she stepped forward, her voice trembling. "Itadori-san, please... I don't want him to fail. I help him study. I just–I don't understand why you hate me so much. I've tried to be respectful. I've tried to be good to him."
She looked genuinely hurt, her lip wobbling. She looked human. But as she spoke, Wasuke felt that grating itch in his soul. That memory of a dark, cramped place he’d never seen.
"I don't care what you've tried!" Wasuke snapped.
As the three of them screamed over one another, the air in the room suddenly grew heavy. It wasn't a sound or a sight; it was a physical pressure that made the floorboards groan. Wasuke’s knees buckled slightly, a wave of nausea rolling through him. For a split second, the gravity in the room felt thick, like he was standing at the bottom of a deep, dark well. It felt powerful, ancient, and utterly disgusting.
Kaori let out a small, choked sob, looking just as confused as the men. She reached out to steady herself on the table, and the weight vanished. She looked at her own hands, terrified, while Jin rushed to her side.
Wasuke bolted upright in bed, his chest heaving, his pajamas soaked in cold sweat. The room was dark, the only light coming from the pale moon through the blinds. He felt a weight at the end of the bed and froze.
It was Yuuji. The boy had crawled into his room, curled into a small ball over Wasuke's feet. The terror in Wasuke’s chest softened into a dull ache. He reached out, pulling the sleeping boy up the mattress and tucking him into his side.
At the moment, Yuuji’s warmth was the only thing that felt real in the world.
"I won't let her," Wasuke whispered into the dark. "Not you, too."
The following afternoon, the world broke. Or rather, the gravity.
Wasuke was in the kitchen, nursing a cup of tea, watching Yuuji play with a set of plastic blocks on the rug. His grandson was frustrated; he was trying to build a tower, but the base kept wobbling.
"Stupid blocks," Yuuji huffed.
He reached out his hand, and Wasuke watched, paralyzed, as the blocks didn't fall. Instead, they drifted upward. They bobbed in the air, weightless, as if the apartment had suddenly been submerged in water. Yuuji giggled, reaching out to poke a floating square, and the boy himself began to lift off the rug, his feet dangling six inches above the floor.
Wasuke dropped his tea. The ceramic shattered, the brown liquid splashing across the linoleum, but the shards didn't just lie there–they hovered for a heartbeat before slamming back down with a sudden, violent force.
Yuuji fell too, landing hard on his bottom. He looked at his hands, his eyes wide with wonder. "Jiichan! Look! I’m a bird!"
Wasuke couldn't breathe. He saw it then. The heritage. The rot. It wasn't just in her eyes; it was in the boy's blood.
The next morning, Wasuke dropped Yuuji off at Sato-san’s with a grip that left bruises on the boy's arm.
"Sato-san," Wasuke said, his voice low and urgent. "Listen to me. Do not let him go outside. Not for the park, not for the garden. Keep the door locked."
Sato-san blinked, startled by the desperation in the old man's eyes. "Itadori-san? Is everything alright? Is it the neighborhood boys again?"
"Just keep him inside," Wasuke hissed. "Please."
The walk back to pick him up that evening felt like an eternity. Wasuke was late - his shift at the warehouse had run over, and every minute he spent away felt like a minute he was losing Yuuji to the dark.
When he finally arrived, Yuuji was sitting quietly on the porch, swinging his legs. He looked up and beamed.
"Jiichan! You’re late again!"
"Let's go. Now," Wasuke grumbled, grabbing the boy's hand.
As they turned the corner, Yuuji looked up at him, his expression bright and innocent. "You shouldn't be so scared, Jiichan. Sato-obasan’s friend is real nice."
Wasuke’s heart stopped. "What friend?"
"The lady with the scratch," Yuuji said casually. "She came over for tea. She played with all the kids. She even gave everyone candy."
Wasuke felt the world spinning. "You... you were with her?"
"Yeah! You were late, so she sat with me on the swing for a little bit before she had to go. She’s real smart, Jiichan. I showed her my floating trick with the pebbles, and she knew exactly what it was!"
Yuuji struggled with the words, his brow furrowed in concentration. "She called it... aunty-gwav-tee? Something like that. She said it’s a gift from my mommy."
Wasuke’s stomach turned over. Anti-gravity. She was naming it. She was claiming him. She had sat there, drinking tea with the neighbor, while she laid her hands on his grandson.
"She’s my friend," Yuuji added firmly. "She said she’ll come back to play again."
"No," Wasuke whispered. "No more."
For the next three days, the apartment became a prison.
Wasuke called Sato-san and told her Yuuji was sick. He bolted the windows. He didn't even go to the market. He sat in his chair, watching the door, while Yuuji grew more restless by the hour.
"I want to go to the park!" Yuuji screamed on the third afternoon, throwing a toy car against the wall. It didn't bounce; it hit the wall with a sickening thud as the gravity around it spiked, cracking the plaster.
"We are staying here!" Wasuke yelled back, his voice raw.
"Why? Because of the lady? She’s nice! You’re just mean! Mean, mean, mean!" Yuuji babbled, tears streaming down his cheeks and his face reddened with anger. "I hate it here! I want to go play! It’s sunny outside!"
"You don't know what's out there!" Wasuke snapped, grabbing the boy by the shoulders. "You don't understand what she is!"
"She’s my mommy!" Yuuji shrieked, the word cutting through Wasuke like a knife.
The air in the room grew heavy. Dangerously heavy. The light fixture in the ceiling began to groan, the metal casing bending under a sudden, invisible weight. Wasuke felt his heart fluttering. He looked at his grandson and saw, for a fleeting, terrifying second, the shadow of something ancient and hungry standing behind the boy.
"She isn't your mother," Wasuke whispered, his voice trembling. "She’s a ghost, Yuuji. And ghosts only want to pull you into the ground."
And suddenly, the heavy, distorted atmosphere in the living room didn’t snap–it dissolved.
The front door, which Wasuke had bolted, chained, and braced with his own failing strength, didn't break. The locks simply clicked open, turning with a mechanical precision that defied physics. The door swung wide, and the humid Sendai air rushed in, smelling of rain and that cloyingly sweet, funeral-home incense.
Kaori stepped over the threshold.
She looked exactly as she had in Wasuke’s dreams, yet entirely different. The school girl was gone, replaced by a woman in a modest, dark trench coat. She looked soft, maternal, and heartbreakingly familiar.
Until the jagged, horizontal seam stitched across her forehead like a gruesome crown came into view.
"Yuuji," she said, her voice a low, melodic hum that seemed to vibrate in the very marrow of Wasuke’s bones. "I told you I’d come for a visit, didn't I?"
"Mommy!" Yuuji’s anger vanished instantly, replaced by the blinding joy of a child who had been told his mother was a miracle. Before Wasuke could tighten his grip, Yuuji wrenched free, his small sneakers thumping against the floorboards as he threw himself into her arms.
"No! Yuuji, get back!" Wasuke lunged, but his legs felt like lead.
Kaori caught the boy with a practiced grace, lifting him and tucking his pink head into the crook of her neck. She looked at Wasuke over the boy’s shoulder, her eyes void of any human warmth.
"You’re a monster," Wasuke spat, his voice trembling with a cocktail of terror and pure, unadulterated disgust. "You’re a parasite. You crawled into my son’s life and ruined him, and now you’re back for the scraps? Get away from my grandson, you freak!"
Kaori didn't flinch. She smoothed Yuuji’s hair, her movements clinical. "You always were so loud, Itadori-san. Even back then, when you were just a shadow over Jin’s life. You haven't changed. Still trying to guard a treasure you don't understand."
"I understand enough to know you’re a bitch from hell!" Wasuke lurched forward, his fist raised, but he froze mid-air. The gravity didn't just increase, it localized. His arm felt like it had been turned to solid iron, dragging his entire torso toward the floor.
Kaori looked down at Yuuji, her expression shifting into something sweet and artificial. "Yuuji, darling, why don't you go to your room and pack your favorite toy? Grandpa and I need to have a very serious talk about your future."
"Is Jiichan okay?" Yuuji asked, looking back at Wasuke’s strained, purple face.
"He’s just tired, sweetie. Go on."
Yuuji hesitated, but the authority in her voice was absolute. He nodded and ran down the hall, the door to his bedroom clicking shut behind him.
The moment the latch clicked, the "mother" vanished. Kaori’s face went slack, her eyes sharpening into something ancient and predatory. She released the pressure on Wasuke, and he collapsed, gasping, before lunging for a kitchen knife on the counter.
He was faster than a man his age should be, but he was nothing compared to her.
Wasuke swung, the blade whistling through the air, but Kaori simply stepped into his guard. She caught his wrist, and the sound of his bones snapping was like dry kindling breaking. He didn't even have time to scream before she drove a palm into his chest.
The force didn't just knock the wind out of him; it felt like his heart had been flattened against his spine. He hit the wall with a sickening crunch, sliding down to the floor as his vision began to tunnel.
Kaori stood over him, looking down with the mild interest of a scientist observing a dying insect. She knelt, her face inches from his.
"You’ve done a decent job keeping the vessel intact," she whispered, her voice a cold rasp. "But he’s mine now."
Wasuke coughed, blood bubbling at the corners of his mouth. He looked up at her, a final, flickering spark of defiance in his fading eyes. "He... he won't be... what you want," he wheezed, his voice a ghost of a sound. "He has Jin’s heart. He’ll... he’ll be the one to kill you."
Kaori smiled, and for a second, the stitches on her head seemed to pulse. "We’ll see."
With a swift, blurred motion, she struck. The world went gray.
Minutes later, the bedroom door opened. Yuuji stepped out, clutching a worn stuffed tiger. "I’m ready, Mommy. Where’s Jiichan?"
The living room was unnervingly clean. The broken tea cup was gone. The blood was vanished. Wasuke’s chair was empty.
"He really wasn't feeling well, Yuuji," Kaori said, her voice back to that soothing, maternal lilt. "His heart is very weak. The doctors had to take him away to a special place where he can rest. He wanted me to tell you that you’re coming to live with me from now on. We’re going to a big, new house."
Yuuji’s face fell. "But... I didn't say bye. I want to see him! I want to tell him I’m sorry for yelling!"
"There’s no time, Yuuji. We have a long train ride."
"No!" Yuuji pulled back, his lower lip trembling. "I’m not going until I see Jiichan! Let me go!"
Kaori’s hand tightened on his shoulder, not enough to bruise, but enough to make the boy go still. The air in the room grew heavy again, just a hint of the crushing weight she could command. "I said we’re leaving. Don't make me disappointed in you so soon, Yuuji."
Yuuji’s knuckles whitened around the worn fur of his stuffed tiger, his small chest hitching with a sob he was trying to swallow. He looked back at the empty hallway, his eyes searching for a shadow, a grunt, a familiar limp–anything. But the iron grip on his shoulder didn't budge. He stumbled, his feet dragging against the floorboards as he was steered toward the open door, his resistance melting into a trembling, hollow silence.
Beneath him, in the suffocating dark of the crawlspace, Wasuke lay twisted among the dust and discarded boxes. Every breath was a wet, jagged whistle that tore through his mangled chest. He tried to scream, but only a thick, metallic heat bubbled up his throat, choking him.
His vision was a narrowing tunnel, but through a sliver of a gap in the wood, he saw them.
He watched the blurry, scuffed toes of Yuuji’s sneakers slide across his field of vision. They were moving too fast, tripping over the threshold. Behind them followed the sway of a dark trench coat, silent and predatory.
The boy’s small shoes vanished into the dim, faulty lights of the hallway.
The heavy thud of the door echoed through the floorboards, vibrating against Wasuke’s broken ribs. Then came the sharp, final click of the deadbolt.
The apartment went still. The air grew cold, settled, and utterly empty, leaving only the sound of a dying man’s heart slowing to the beat of the silence.
