Mizuki sat in the front row. Posture perfect. Notebook open. Pen poised. She had already written the date and the subject heading in her neat, precise handwriting, complete with the tiny spiral flourish she'd been adding to her headers since middle school. Her blazer was buttoned. Her hair was immaculate, that silver clip still pinning back loose strands. She was the picture of academic readiness and had been since third grade, when she'd realized perfection was the only way to be seen in a house where both parents left before breakfast and came home after dinner. The silence of the house had taught her discipline. The absence of her parents had taught her self-reliance.

Sato had claimed his usual spot at the back, as far from the teacher's gaze as physically possible. He was still not wearing his uniform - just a wrinkled gray t-shirt with a cartoon cat and jeans. Iwamoto had either given up or was saving his energy for a more dramatic intervention later. The t-shirt might have been ironic or might have been laundry day ; even Sato wasn't sure anymore. He had his phone in his lap, hidden under his desk, scrolling with lazy disinterest. The screen cast a faint blue glow on his chin, illuminating the stubble he kept forgetting to shave. He hadn't slept more than two hours the night before, and the fatigue was a familiar weight behind his eyes.

Ezume sat near the left wall, close to the window and radiator. The radiator was off - too warm for it - but he liked the spot. It gave him a view of the street outside, where a single cherry tree was beginning to shed its blossoms. More importantly, it gave him a wall to lean against when lessons dragged on. His blazer hung open over a faded "Umbrella Man" t-shirt - a reference to a conspiracy theory about the Kennedy assassination. No one had ever asked him about it. The shirt was soft from years of washing, a gift from his mother that he'd never stopped wearing.

His mind was elsewhere. Specifically, on the photo. The photo he'd taken last night. Saved in three separate folders, backed up to the cloud, burned into his eyelids. Kama, fleeing through the street. Her face half-covered in that bone-white mask. Eyes blazing red. Teeth too long and too sharp. Her coat torn, her arm streaked with blood.

She's a boogeywoman. A real boogeywoman. And I have proof.

The teacher's voice was a distant hum, explaining the discriminant formula - b squared minus four a c. His fingers drummed against his thigh. His knee bounced under his desk, making it vibrate faintly. He was anxious. Excited. Terrified. Every possible emotion colliding in his chest. The photo was a physical weight in his pocket, a piece of evidence that could change everything. But what if Sato didn't believe him ? What if the photo was too blurry ? What if Kama had another explanation, just like she'd had explanations for everything else ? The fangs were prosthetics. The eyes were contacts. The window jump was acrobatics. What would she say about the mask ? That it was cosplay ? A Halloween costume?  That he'd imagined the whole thing ?

The door opened.

Iwamoto Monji stepped in, his massive frame filling the doorway. Indigo kimono immaculate. Moustache perfectly trimmed. Expression unreadable. He crossed to the teacher's desk with the slow, deliberate stride of a man who had never been hurried in his life, leaned down, and murmured something in her ear.

The teacher's eyebrows rose. She nodded once. Iwamoto straightened, turned, and left without a word. The door clicked shut behind him.

The teacher set down her chalk and dusted her hands. "Well. This is somewhat unexpected. It seems we'll be welcoming a new student today. She comes to us on special recommendation from a senior figure in the regional education board. She's joining us directly from Kyoto." She turned toward the door. "You may come in now, dear. Please introduce yourself to the class."

A murmur rippled through the room. A new student this late in the year ? That was unusual. Heads turned toward the door, curious. Mizuki's pen stopped moving. Sato glanced up from his phone. Ezume didn't move at all. His heart was suddenly pounding so hard he could hear it in his ears. A new student. From Kyoto. The timing was too perfect.

The door swung open. Kama walked in.

She was not what anyone expected.

Blonde hair tied back in a high ponytail that swished with every step. Pale pink off-the-shoulder sweater that left her collarbones bare and hugged her figure in a way the standard uniform definitely did not. Short white skirt. White sneakers. The outfit radiated a casual confidence that made the rest of the class, in their identical navy blazers and pleated skirts, look like they were attending a funeral.

She walked to the front with the easy stride of someone who had never felt out of place in her life. She turned to face the class, planted her hands on her hips, and smiled - a broad, open smile that showed teeth and didn't care.

"Yo," she said. "Name's Satsu Kama. Just transferred from Kyoto. I'm eighteen, so yeah, you can totally try to hit on me, boys." She punctuated this with a wink, slow and deliberate. Someone in the back row - a boy named Tanaka who'd never spoken to a girl in his life - made a strangled noise. The teacher's eyebrows climbed toward her hairline.

"Don't have any family left. Don't have a house, either - been living in a hotel since I got to Toyama. Sold my old apartment in Kyoto to pay for it. Pretty sweet deal, honestly. Hotel life's not bad. Fresh towels every day." She shrugged, the pink sweater slipping a little further off her shoulder. "Don't remember much about my past. Just know my family's dead. Memory's a bit fried. But hey, clean slate, right ?"

She said this with a cheerful, almost teasing smile, as if discussing the weather. The class stared in stunned silence. Someone whispered, "Did she just say her family's dead ? Like, with a smile? "

"Anyway," Kama said, giving a little wave. "Looking forward to getting to know you all. Try not to be too boring."

Mizuki, in the front row, frowned. Something about this girl bothered her. The way she carried herself. The way she smiled. That absolute, unshakeable confidence. Mizuki had spent years cultivating that exact confidence, building it through perfect grades and perfect grooming. Seeing it worn so effortlessly by a stranger felt like an insult. The girl hadn't even buttoned her sweater properly, yet she stood there like she owned the room.

Sato, in the back, let out a low chuckle. He liked her already. She was exactly the kind of chaos this class needed—the kind that made mornings worth getting up for, even on two hours of sleep.

Ezume hadn't heard a word. He was staring at the girl who'd broken into his apartment. The girl with predator teeth and glowing eyes. The girl who'd fled into the night with blood on her arm. Now introducing herself like nothing had happened. The disconnect was so jarring he felt dizzy.

His heart pounded. The photo was right there in his pocket. He could stand up, point at her, show everyone - but his body wouldn't cooperate. He just sat frozen.

"Take a seat wherever you like, Miss Satsu. We'll find you a proper desk by tomorrow."

"Cool. Thanks."

Kama scanned the room. Her eyes passed over Mizuki without stopping, flicked past Sato with a tiny, almost imperceptible nod of recognition - a private greeting between two people who'd shared food and a Sunday afternoon. Then her gaze landed on Ezume.

Her smile widened.

She walked down the aisle past rows of staring students and jealous whispers. More than one boy felt his heart rate increase as she passed. She didn't seem to notice any of them. She had only one target.

She stopped directly in front of the empty seat to Ezume's left. There were empty seats all over the classroom. She had chosen this one. Deliberately. Obviously. She wanted everyone to see.

She dropped into the chair, shrugged off her bag, and leaned over until her bare shoulder pressed against Ezume's blazer-clad arm. He could feel the warmth of her skin through the fabric. Patchouli and green tea. The same scent as in his bedroom at midnight.

"Hey, amigo," she murmured, low enough that only he could hear. The word was casual, teasing, private. It sent a shiver down his spine. Then her tone switched satirically solemn "Might I borrow thou a pen ?"

Ezume's brain stopped working. "A what ?"

"A pen ?" She mimed scribbling on paper. "Need to take notes. For class. School. Education. Heard of it ?"

He fumbled in his pencil case and handed her the first pen he found - a cheap blue ballpoint with a chewed cap. She took it with a smile that was entirely too satisfied. Then, loudly enough for the entire class to hear: "Hey. Quit staring at my thighs."

Every head turned. The silence was immediate and absolute. Ezume's face went crimson. His hands flew up as if to defend himself, but he had no defense. He hadn't been staring at her thighs; he'd been staring at the floor, trying to process the fact that the girl who'd tried to bite him was now asking for a pen. No one would believe that.

The class erupted in snickers. A girl in the second row whispered to her friend, who covered her mouth. Sato made a low whistle that lasted far too long. The teacher rapped her knuckles on the desk.

Kama, utterly unbothered, opened her notebook and began writing. Her handwriting was messy, barely legible, but she was writing something, and that satisfied the teacher, who turned back to the board with a sigh.

Ezume stared straight ahead, face burning, heart hammering. This is going to be a very long day.

The bell rang for break. The classroom dissolved into the usual chaos of shuffling papers and scraping chairs. Students clustered into groups, comparing notes, complaining about homework, making lunch plans. The teacher gathered her materials and escaped with the relieved haste of someone who'd been through an ordeal.

Kama stretched her arms over her head, spine cracking audibly. She'd been doodling in her notebook for the past twenty minutes - small, intricate patterns of teeth and claws that would have been unsettling if anyone had looked closely. No one had. She stood, smoothed down her skirt, and turned toward the front of the room.

"Hey," she said, sliding up to Mizuki's desk with a grin. "You're Mizuki, right ? Sato told me about you. Class president. Future doctor. Super smart. I'm Kama."

Mizuki looked up from her notebook. Her expression was perfectly neutral. She studied Kama's face for a long moment, taking in the sharp cheekbones, the blue eyes, the confident smile, the way the pink sweater sat on her shoulders. Then her gaze dropped, very deliberately, to Kama's chest. She stared for three full seconds. Her eyes lifted back to Kama's face. Her expression did not change.

She stood, pushed her chair in with a precise, controlled motion, and walked around her desk. She positioned herself directly behind Sato, who was still scrolling through his phone with the relaxed posture of someone who had no idea what was about to happen. Mizuki pressed her mouth against his shoulder, as if whispering a deeply personal secret, but her voice was perfectly audible.

"I don't like her," she said, her tone flat and matter-of-fact. "We need to find a vat of acid and make her disappear."

Sato's phone slipped from his fingers and clattered onto his desk.

Kama's jaw dropped. Genuine, unfiltered shock. She had been threatened by Sunakake. Dragged by the ears by Tamonten. Insulted by Urazuki in ways that would make a sailor blush. But never, not once, had she been told that someone needed a vat of acid to dissolve her, delivered with the calm, measured precision of a class president. The sheer absurdity was staggering.

"Hey ! I heard that ! What the hell is wrong with you people ? You're all crazier than the last one !"

Sato started laughing so hard he had to brace himself against a desk. His shoulders shook. Tears formed at the corners of his eyes. This was, without question, the funniest thing he'd ever witnessed in a classroom.

Mizuki stepped out from behind him, arms crossed. Her posture was perfect. She was the picture of righteous indignation. "I'm not crazy. I'm just honest."

"Honest about wanting to dissolve me in acid ?"

"Hyperbolic expression of personal discomfort. I'm allowed to have feelings."

"You're allowed to have feelings about murdering me ?"

"I didn't say murder. I said disappear. There's a difference." Her voice was calm, measured, as if explaining a point of grammar. "Disappearance implies a lack of evidence. Murder implies a body. I was very clear about my phrasing. If I had meant murder, I would have said murder. I didn't. You're the one who jumped to murder. What does that say about you ?"

Kama stared at her. The room was silent. Then Kama threw her hands in the air. "You're insane. I've met a lot of people, and you're in the top three."

Mizuki's expression didn't change, but something flickered in her eyes - a tiny spark of satisfaction. "I'll take that as a compliment."

"It wasn't one !"

Mizuki smiled, a tight, knowing smile, and returned to her desk with the poise of a queen retreating to her throne.

Sato wiped tears from his eyes. "This is the best first day of school I've ever seen. I need to lie down. I'm already sitting down. I need to lie down more."

Kama shook her head slowly, watching Mizuki return to her notebook. "I don't know whether to slap her or offer her a job. She'd make a terrifying enforcer."

Sato, still wheezing, managed, "Welcome to our group. This is normal. Well, not normal. But it happens. When she's feeling feisty."

Kama turned back to him, one eyebrow raised. "Feisty ? She threatened to dissolve me in acid."

"That's feisty for Mizuki."

And somewhere in the chaos, Ezume sat at his desk, watching Kama with haunted eyes. The photo was still in his pocket. The truth was still waiting. Lunch was only two hours away. Despite everything - the mask, the claws, the evidence burning a hole in his pocket - he found himself smiling.

Maybe today wasn't going to be so bad after all.
