Imagine Obanai, before becoming a Hashira, getting accused of murder after being caught by some police when he still had his katana out. Some demon had been killing frequently in the village, the same demon Obanai had just killed, but since it had disappeared, inevitably the police figured Obanai was some cannibal or something. They arrested him, putting him in a jail cell unless he was proven innocent.
When he was thrown in, Obanai began panicking. Which was normal, of course. Because this (so-called)criminal had just been caught and incarcerated! There was no worry of his sporadic breathing. Except—
Except now he was clawing at the bars and hyperventilating to the point he seemed unable to breath, tears streaking down his cheeks and staining that peculiar mask of his. One of the police—a woman—walked towards him, concerned.
One of the other police warned her to leave because, despite the fact that they had taken his sword, he could still be very dangerous. But she assured him that this was only a child, that there was no way he could do anything; he was scared, she needed to console him so he could calm down and answer their questions. And so she knelt by the cell, not quite in arm rage of Obanai if he thought to reach out. But instead, he did the opposite, recoiling at her presence. A small whimper escaped him and he curled up in a ball, a hand reaching up and clawing at his mask subconsciously, an overwhelming amount of terror written in his eyes.
“No…” Obanai whispered. His voice was raspy, scratching against the walls. The diminutive word was small but seemed to hold so much emotion that the police approaching him physically stumbled back, worry rising.
“It’s okay… We just need to talk to you,” she murmured, trying on a gentle tone. She had been amongst the ones who didn’t believe he had done anything. After all, there were no traces of blood on his katana. He could’ve wiped it, of course, but then why had he been holding it out in such a stance? “It’s… It’s safe here.”
The words had the opposite effect intended; Obanai scampered back, pressing against the far wall. He shook his head quickly, his hair spinning around him, covering his bicolored eyes. He was shaking, and a quiet sob wrecked his body. He could barely breathe now, memories returning in flashes and overwhelming him. He was stiff, gasping pleads muffled by his bandages. He was sorry, he was sorry, he promised not to run away again, he promised, he would stay, he would stay, he would—
But then he was in familiar arms, a Demon Slayer he’d worked with recently carrying him. They were outside, the sky bright and blue and the air blissfully fresh and cool. The Demon Slayer glanced down, his eyebrows furrowed in concern but relaxing slightly when he noticed that Obanai had awoken.
“It’s okay. I got you out. The Master is taking care of everything, I think,” he reassured him. Slowly, carefully, he set Obanai down, helping him sit. “Maybe we shouldn’t go into cities too often, hm?” he remarked, a tired sort of amusement quirking his lips.
Obanai nodded numbly. He was outside. He was safe.
The Demon Slayer sat beside him, resting a comforting hand on his back. “It’s okay,” he repeated quietly. “You’re okay.”
