Chapter Text
Days at the shrine settled into an awkward rhythm that never fit quite right. Momo got up at seven with the gentle shh-shh-shh of Seiko's broom across the engawa, a sound as dependable as her own pulse. Okarun got up at seven-fifteen to the scent of rice and miso.
Reiko, who seemingly never slept and instead spent her nights tormenting her own reflection in convenience store windows, landed on the torii gate around dawn with the air of a queen returning to a kingdom diminished in her absence.
By eight they ate breakfast together with little conversation. The words happened later, out in the ruins where the air was thin and the talking easier. By eight-thirty, Seiko was on her third cigarette of the morning and buried in her notes.
By nine, they were walking.
It wasn't comfortable. But it was consistent. And consistency, Momo was discovering, was its own kind of mooring.
The shopping bag appeared on the fifth morning. Okarun went to put his futon away in the spare room—a habit Seiko had drilled into him with a single raised eyebrow on day two—and found it there, sitting on the shelf. A plain plastic bag from a discount store.
Inside: a package of underwear, three plain t-shirts, two pairs of socks, a pair of dark pants that looked like they'd fit, and a pair of simple sneakers.
He stared at the bag. There was no note. There didn't need to be. Seiko had noticed.
He'd been managing. Momo dug a few sets of hoodies and sweats out of her closet for him to wear. He secretly scrubbed the single pair of underwear he'd arrived in with hand soap each night and hung them behind the spare room door to dry—they were usually slightly damp when he put them on. And then the shoes, or lack thereof. He'd been wearing a pair of borrowed Crocs from the genkan, the kind Seiko used for gardening, two sizes too small. His toes hung over the edge. He'd said nothing about any of it, because what was he supposed to say?
But she'd noticed anyway. The Crocs. The uncomfortable shuffling. The late night scrubbing. The fact that he never seemed to have anything clean to put on. She'd filed it all away and walked to a discount store and solved the problem without discussion, without fanfare, without even making eye contact about it.
Momo walked past the open door, glanced in, and saw him standing there holding the bag like it was incriminating evidence.
"Grandma went shopping," she said.
"I can see that."
"Shoes, too."
"Yeah."
"Yeah."
He pulled out one of the sneakers and turned it over in his hands. Plain white. Practical. Probably the cheapest pair in the store. "I've been wearing gardening clogs that don't fit for five days."
"I know."
"You didn't say anything."
"I thought you were committed to the look."
Okarun made a sound that might have been a laugh if it hadn’t been so choked.
Momo pushed off the doorframe. "With Grandma, you don’t have to figure out the right words. You just say thank you and mean it."
She continued down the hall.
At breakfast, Okarun bowed a fraction deeper than usual. He was wearing one of the new shirts.
"Thank you for the meal. And for... everything else."
Seiko didn't look up from her bowl of rice. She coughed lightly into her fist, then waved her chopsticks vaguely in his direction.
"There's more where that came from. Don't get weird about it."
It was the most Seiko response possible. Okarun felt something loosen in his chest that he hadn't realized had been tight.
The thin zone mapping began in earnest on the sixth day.
Seiko laid a crumpled paper map on the kitchen table—a real, honest-to-god paper map, because she didn't trust phones for anything important—and pointed to a few spots with a bright red pen. Old temples on the outskirts of the city. A neglected shrine squeezed between an apartment building and a parking garage. A disused cemetery with graves dating back to the Edo period.
"These are my predictions," she said, tapping her pen on the paper. "Based on the model, old sites with emotional history should have thinner suppression. I want you to visit each one and confirm."
"You're not coming?" Momo asked.
"I have a shrine to run. And my knees aren't what they used to be." She lit a cigarette, smoke pluming around her head. She coughed lightly before continuing. "Take the crow."
"I am not a pack animal!" Reiko shouted from outside.
"You're reconnaissance. Wet your beak."
"That expression is disgusting."
Their first destination was a small, dusty Inari shrine hemmed in by modern structures. The torii gate was weathered concrete, the painted eyes of the kitsune guardians chipped and faded. Someone had left a can of Fanta on the offering table. Either it was a profound sign of modern reverence or utterly sacrilegious. Momo stood in the center of the shrine grounds and closed her eyes.
"Anything?" Okarun whispered.
"It's thin. Thinner than the city's normal suppression. Not like the ruins, though. The ruins are a door, this is like... a window screen."
"So the pattern holds?"
"The pattern holds."
Okarun jotted the location in his notebook with a small annotation: Mild thinness. Comparable to shrine grounds. Confirms historical/spiritual correlation.
Reiko perched on the fox statue's head and peered down at the Fanta with undisguised contempt.
"Soda? As an offering? Humanity deserves whatever it gets."
The second site was a sprawling, weed-choked temple cemetery on the city's fringe. Grave markers had crumbled and names were faded under centuries of rain and neglect. Weeds had long since taken over the paved paths. The air here felt thick and silent. Momo sensed the thinness even before she closed her eyes. It was stronger than the shrine, almost as strong as the ruins.
"This is a good one," she murmured. "Really good."
"What makes it good?"
"History. Loss. Generation after generation of people burying their loved ones, their grief imprinted on the land." She opened her eyes. "Death leaves marks, remember?"
Okarun didn't answer. His gaze was fixed on a moss-covered headstone near the far edge of the cemetery, its inscription nearly illegible.
"You alright?" Momo asked.
"Yeah. Just thinking." He turned away from the grave. "The tunnel will be on the map, won't it? If historical sites are thin, the tunnel has to be one of the thinnest."
Momo couldn't offer an opinion on that.
Reiko was uncharacteristically quiet.
"Reikrow Cawshima" happened on the seventh day.
They were walking between thin zone sites—a temple in the northeast district and a supposedly haunted well that Seiko wanted them to check—and Reiko was in rare form.
"This city is an architectural abomination," she announced from her perch on a traffic light. "Every building is exactly the same shade of beige. Did humans develop blindness? Is that the problem?"
"We don't design buildings for crows," Okarun countered.
"You don't design them for anyone with eyes. Look at that." She gestured with a wing at a bland office tower. "What is that? A rectangle? That's not a building, that's an insult to geometry."
"It serves its purpose."
"It's offensive." She swooped down to a puddle on the sidewalk and examined her reflection. "Ugh. The lighting here is atrocious. My feathers look drab."
"You're black," Momo pointed out, rolling her eyes. "Black doesn't get drab."
"Everything looks drab in bad lighting, Ayase. You wouldn't understand; you probably do your makeup in a funhouse mirror."
"I haven't worn makeup since we got here."
"I can tell."
Momo grit her teeth. Okarun spared a sidelong glance in her direction. Reiko had a gift for landing directly on wounds she didn't know existed. Momo had barely worn makeup since the white light. Partly because she felt too drained. Partly because the makeup on her dresser belonged to a version of her that didn't exist—bought with money that girl earned, chosen according to that girl's tastes. Using it felt like stealing from a stranger. Looking in the mirror without it felt like looking at a stranger too. There was no winning.
"She's quiet," Reiko observed. "Did I hit a nerve?"
"Keep flying, bird-brain," Momo shot back.
"That's not my name."
"It's not not your name."
They crossed the street. Reiko followed, muttering to herself. A businessman walking past gave the crow a strange look—a talking bird was unusual even when reactions were suppressed—but kept walking. People in this city were very good at not seeing things.
The next puddle was apparently even worse.
"This is a personal insult," Reiko said, craning her neck over the water. "I look like I fell into a soot factory. I look like someone set fire to a sock. I look like—"
"Reikrow Cawshima," Momo muttered under her breath.
Okarun choked.
The crow went absolutely still.
"I beg your pardon?"
"Nothing.
"No. No, I heard you." Reiko's head rotated almost one hundred and eighty degrees, black eyes fixing on Momo with the intensity of a laser sight. "What did you call me?"
"I didn't call you anything."
"You called me Reikrow Cawshima."
"Did I? I don't remember that."
"You are lying! You are lying with your human mouth and your asymmetrical hair and your complete lack of respect for—!" Reiko launched herself off the pavement and dove directly at Momo's head.
What followed was approximately thirty seconds of chaos. Reiko perched on Momo's shoulder and began viciously ripping out her hair with her beak and raking her scalp with one claw while Momo flailed and Okarun tried unsuccessfully to intervene.
"Get off—stop it—you demon bird—!"
"Take it back!"
"I am not taking anything back, it was funny—OUCH!"
"Reikrow Cawshima!" Reiko screeched, pulling harder. "Reikrow Cawshima! I am a being of pure conceptual terror and you are calling me PUNS!"
"It's a good pun!"
"IT'S A HORRENDOUS PUN!"
Okarun managed to get a hand between them and Reiko redirected her assault to his glasses, which she pecked with enough force to leave a scratch on the lens. He yelped and stumbled backward into a telephone pole.
Finally—after Momo lost approximately six strands of hair and Okarun's glasses were permanently scuffed—Reiko retreated to the top of a vending machine, feathers ruffled like a grumpy parakeet and black eyes burning like chips of volcanic rock.
"I'm going to find every single reflective surface in this city," she vowed, voice low and menacing. "And I'm going to make sure you regret the day you were born."
"Worth it," Momo said, rubbing her scalp.
"Your scalp will be worth nothing when I'm done with it!"
"Does that sentence even make sense?"
"NO! THE MEANING IS NOT IMPORTANT!"
They completed the thin zone map in the afternoon. The well was a bust; Seiko had flagged it based on local folklore about a drowned woman, but whatever thinness had once existed there had long since sealed over. Momo felt nothing. Okarun noted the null result in his book. Reiko remained strictly non-conversational with both of them.
When they arrived back at the shrine, Seiko was sweeping the stone path. She looked up as they approached and took in the scene: Momo with disheveled hair and a scratch on her neck, Okarun with a scuffed lens and a sheepish expression, Reiko radiating fury from atop the torii gate.
"What happened to you two?"
"Reikrow Cawshima," Momo said.
Seiko paused mid-sweep. She coughed once into her fist before a faint, fleeting smile tugged at the corner of her mouth and vanished as quickly as it had appeared.
"That is a good pun," she said, then continued sweeping.
"THANK you!" Momo said.
"TRAITOR!" Reiko squacked from the gate. "You're all traitors! This shrine is a nest of vipers!"
"It's a shrine," Seiko said. She coughed lightly again, then added, "And you're a bird. Act like one."
"I am NOT a bird. I am a YOKAI. I am a being of—"
"Bird-brain," Seiko said flatly, and kept sweeping.
Reiko's beak opened. Closed. Opened again. No sound came out. For perhaps the first time in her eighty years of existence, Reiko Kashima had been rendered completely speechless by a sixty-three-year-old woman with a broom.
The silence lasted exactly four seconds.
Then Reiko swooped down from the gate, flew directly over Momo's shoulder, and deposited a single, perfectly aimed dropping onto the fabric of her hoodie.
"AH—GROSS—"
"REVENGE!" Reiko shrieked, already airborne and climbing. "REVENGE IS A DISH BEST SERVED WARM AND DIGESTED!"
She disappeared over the roof of the shrine, cackling.
Momo stared at her shoulder in horror. Okarun was making a sound that might have been coughing but was definitely laughing. Seiko had stopped sweeping entirely and was watching the sky where Reiko had vanished with an expression that was almost, almost, fond.
"There's laundry soap in the storage building," she said. "You know where the washing machine is."
"Grandma, she pooped on me!"
"Actions have consequences." Seiko lit a cigarette. "Next time, don't call the Yokai a pun name to her face."
She walked toward the house, trailing smoke and what might have been the ghost of amusement.
Momo looked at Okarun. Okarun, very carefully, looked at his notebook.
"If you write 'Reikrow Cawshima' in there—"
"It's already in here."
"I hate everyone in this shrine."
The laundry became its own kind of ritual.
Momo had been putting it off for days. The washing needed to be done. Seiko's clothes, her own clothes, the accumulated wear of a week spent walking through ruins and thin zones. But there was something at the bottom of her bag she hadn't wanted to touch.
She pulled it out now in the storage building's laundry room, surrounded by incense boxes and Seiko's notebooks and the old stone washbasin that predated the washing machine by at least a century. Okarun's clothes. The ones he'd been wearing the day they arrived. The bloodstains had dried dark brown against the fabric, almost black in places.
Momo stood at the stone basin, holding the shirt in both hands, staring at the stains.
The washing machine could handle the rest of the load; her hoodie, Seiko's blouses, Okarun's new clothes. But blood needed to be scrubbed by hand.
This blood came from the other world. From a battle that technically never happened. From wounds that technically never existed. The rewrite had erased the cause but not the evidence. The shirt was still here. The stains were still here. A physical object that remembered even when the world didn't.
She started scrubbing.
The water was cold. The soap was harsh. Momo scrubbed until her knuckles went raw and the stains had faded from brown to a faint rust color, and then she kept scrubbing.
She didn't hear Okarun approach.
"Miss Ayase?"
She looked up. He was standing in the doorway of the storage building, framed by the afternoon light, wearing one of the discount store shirts and the new sneakers. His expression was unreadable.
"These are the clothes you were wearing," Momo said. "When you arrived. When we arrived. They were in my bag." She held up the shirt. The stains were still visible, ghost-brown against the wet fabric. "The blood is still here."
Okarun walked over and knelt beside the washbasin. He looked at the shirt. He looked at Momo's raw knuckles. He didn't say anything about either.
"Let me help," he said.
He took the shirt from her hands and began scrubbing. Momo watched him work in silence. The water turned faintly pink and then clear again.
Neither of them said what they were thinking: this was the only physical evidence that the world they remembered existed. A bloodstained shirt that didn't belong in this reality. Proof that something had happened to them, even if the something had been erased.
"Thank you," Okarun said eventually. "For keeping them."
"You needed clothes."
"That's not what I'm thanking you for."
Momo looked at the shirt. The stains were almost gone now—just faint shadows that would probably never wash out completely. She took it from his hands and wrung it out, then set it aside for the washing machine.
"You're welcome," she said.
They finished the laundry together, loading the rest into the machine and listening to it rumble to life. Around them, the storage building was quiet—incense and old paper and the lingering ghost of cigarette smoke. A room full of evidence that Seiko had never stopped believing.
Seiko watched them from the kitchen window for a moment, then turned away and lit another cigarette.
That night, Momo said it again.
They were sitting on the engawa after dinner. Seiko had gone inside to review her notes. Reiko was somewhere in the city, probably admiring herself in a department store window. The sky was clear and cold and full of stars that looked exactly like the stars in the other world.
"Reikrow Cawshima," Momo said, testing the words.
Okarun snorted. "She's going to poop on you again."
"Worth it."
"She scratched your scalp."
"I've had worse. I've been thrown through walls by aliens. A crow scratch is nothing."
"A Yokai crow scratch."
"A Yokai crow scratch is still just a scratch." Momo leaned back on her hands. "She's growing on me."
"Like a fungus."
"Like a really annoying, really vain fungus with a poop-based revenge system." Momo paused. "I think she likes us."
"She pooped on you."
"Everyone shows affection differently."
Okarun laughed. It was a small sound, surprised out of him, and Momo realized she hadn't heard him laugh since they arrived. Not really laugh. The kind of laugh that came from somewhere other than politeness or exhaustion.
"Progress," she said.
"What?"
"Nothing."
Inside the house, Seiko closed her notebook and lit her final cigarette of the night. She coughed softly into her fist before taking the first drag. Outside, the torii gate stood dark and silent against the sky. And somewhere across the city, a crow was staring at her reflection in a darkened shop window, trying to remember something she couldn't quite name.
The routine held.
Tomorrow, they would return to the ruins. The day after, they would visit the tunnel. The wall was still there, still thick, still pressing down on everything they used to be.
But it had moved an inch. And an inch was enough to keep going.
