The fluorescent lights hummed overhead, casting their flat institutional glow across Classroom 3-A. Twenty-one desks occupied by twenty-one third-years, their uniforms pressed and postures varying from rigid attention to slouched disinterest. The April rain streaked the windows in diagonal lines, and the smell of wet concrete drifted through the ventilation system. Shota stood at the front of the room, capture weapon loose around his neck, his expression suggesting he'd rather be literally anywhere else.

Yoru hovered near the door, a tablet clutched against her chest, her crimson eyes tracking Shota's every micro-movement. The way he rubbed the back of his neck. The slight tension in his jaw. The particular quality of exhaustion that clung to him today—heavier than usual, she noted, probably hadn't slept well, likely patrolled longer than he should have. She'd check the patrol logs later.

His phone buzzed. Shota glanced at the screen, and something in his posture shifted—minute, barely perceptible, but Yoru caught it. Nezu. The principal only called during class for emergencies or bureaucratic nonsense, and Shota's expression suggested the latter.

He looked up from the phone. "I need to take this." His voice was flat, the verbal equivalent of a shrug. "Kurogane, take over until I get back."

Yoru's spine straightened. Her lips curved—not quite a smile, something more proprietary. "Of course, Aizawa-sensei." The honorific landed with a particular emphasis, warm and slightly too intimate for professional context. We'll be fine. We're always fine.

Shota didn't acknowledge the plural pronoun. He never did. He simply walked out, the door sliding shut behind him with a soft pneumatic hiss.

The temperature in the room seemed to drop.

Yoru turned to face the class, and the warmth that had softened her features when Shota was present evaporated like mist off hot pavement. Her crimson eyes swept across the students with the detached assessment of someone cataloging inventory rather than observing people. Twenty-one bodies. Twenty-one potential distractions from the only thing that mattered, which had just walked out of the room.

She settled into Shota's chair at the front of the room, crossing one leg over the other, the tablet now resting face-down on the desk. She didn't look at it. She didn't look at the lesson plan Shota had left displayed on the main screen—something about advanced tactical positioning in urban environments, important material, the kind of thing third-years needed to master before graduation.

Yoru gazed at the rain-streaked window instead.

Ten seconds passed. Twenty. The students exchanged glances. Katsuki's jaw tightened with barely contained irritation. Izuku's hand hovered uncertainly over his notebook. Shouto simply watched, his heterochromatic eyes tracking Yoru's blank expression with unreadable interest.

"Uh..." Momo raised her hand, her voice careful, diplomatic. "Kurogane-sensei? Should we continue with the tactical positioning module?"

Yoru's gaze didn't move from the window. "No."

Silence. Eijirou leaned toward Katsuki, whispering something that earned him a sharp elbow to the ribs.

"Is there... a different lesson you'd like us to work on?" Momo tried again, maintaining the polite persistence of someone accustomed to difficult authority figures.

"No."

Denki's hand shot up. "Can we at least do something? This is super awk—"

"No." Yoru's voice remained flat, uninflected, as if she were declining offers from a telemarketer rather than addressing a room full of students. She examined her nails—short, practical, unpainted. The amethyst ring on her right hand caught the fluorescent light.

*Ochaco whispered to Tenya, "Is she always like this when Aizawa-sensei leaves?"

Tenya's arms moved in sharp, agitated gestures. "This is highly irregular! Educational standards require—"

"I can hear you," Yoru said without looking. "The acoustics in this room are excellent. Built that way intentionally—forces students to be mindful of what they say." A pause. "You should apply that principle more often, Iida."

Tenya's mouth snapped shut. His shoulders squared with offended dignity.

Katsuki slammed his palm on his desk. "The hell is your problem? You're supposed to be teaching!"

Yoru finally looked at him. Her expression was utterly blank—not angry, not amused, not anything. Just empty. "I'm supervising. There's a difference."

"That's bull—"

"Bakugou." Yoru's voice dropped half a register, quiet in a way that somehow filled the room more than shouting would have. "You're a third-year. You've passed the provisional exam. At this point, you should be capable of independent study without needing someone to hold your hand through tactical positioning." She tilted her head slightly. "Unless you're telling me you haven't mastered the material."

Katsuki's eye twitched. A vein pulsed in his temple. But he didn't have a comeback—she'd framed it as a challenge to his competence, and responding with anger would confirm the implication. He ground his teeth and said nothing.

Yoru returned her attention to the window. The rain was letting up, the streaks on the glass becoming intermittent. Somewhere in the building, Shota was dealing with whatever Nezu wanted. Probably something tedious. Probably something that would put him in a worse mood than usual. She should have coffee ready when he got back. The cheap kind he preferred, reheated twice.

The minutes crawled.

Mezo shifted uncomfortably in his seat, his multiple arms twitching with restless energy. Tsuyu rested her chin on her hand, watching Yoru with unblinking amphibian eyes. Fumikage's dark shadow rippled beneath his desk, mirroring the room's collective tension. Minoru—perpetual Minoru—opened his mouth to say something, caught Hanta's warning glare, and thought better of it.

Izuku's hand rose again—tentative, determined, the hand of someone who couldn't help asking questions even when the atmosphere suggested questions were unwelcome. "Kurogane-sensei, I had some questions about the tactical positioning module, specifically about how to account for variable Quirk ranges in formation—"

"Figure it out yourself, Midoriya." Yoru's tone carried no malice, just absolute disinterest. "You've analyzed enough Quirks by now to calculate ranges independently. Stop asking other people to do your thinking for you."

Izuku's hand lowered slowly. His expression flickered—hurt, then confusion, then something closer to understanding. He'd noticed the pattern, maybe. They all had. The way Kurogane-sensei's attention vanished the moment Aizawa-sensei left the room, like someone had cut a puppet's strings.

Yoru's tablet buzzed. She glanced at it—a message from the main office, routine scheduling update. Irrelevant. She set it aside without responding.

The door slid open.

Yoru's transformation was instantaneous.

One moment she was a slouched silhouette against the window, radiating cold disinterest. The next she was standing, tablet in hand, posture perfect, her voice warm and engaged as she turned toward the front of the room—

"—and that's why spatial awareness becomes critical in urban environments with limited reflective surfaces." She tapped the tablet, and the main screen shifted to a detailed diagram of tactical formations. "The key is identifying alternative teleportation points before you need them. Does anyone have questions about the principles we just covered?"

Her smile was bright, professional, utterly convincing.

Shota paused in the doorway, his phone still in hand, his tired gaze sweeping the room. The students were staring at Yoru with expressions ranging from bewilderment to outrage. The diagram on the screen was clearly new—she'd pulled it up in the half-second between the door opening and him looking at her.

Izuku's hand shot up. "Kurogane-sensei, you didn't actually cover any of that—"

"I covered it extensively, Midoriya." Yoru's voice was honey over glass. "Perhaps you weren't paying attention? I know how easily distracted you can be." She turned to Shota, and her entire demeanor softened—the hard edges smoothing, the professional mask warming into something more personal. "Aizawa-sensei. Everything alright? Nezu's calls usually run longer than that."

Shota stared at her for a long moment. His eye narrowed slightly—the particular narrowing of a man who suspected something was off but couldn't identify what. The students' faces were a study in suppressed reactions: Katsuki looking like he wanted to explode, Izuku's hand still raised in protest, Momo's diplomatic mask struggling to contain her disbelief.

"Fine," Shota said finally, pocketing his phone. "Just a scheduling confirmation. Continue the lesson."

"Of course." Yoru stepped aside, returning to her position near the door, tablet clutched to her chest. Her crimson eyes tracked Shota as he moved to the front of the room, and something in her expression shifted—a softening that had nothing to do with professionalism and everything to do with the gravitational pull she'd been orbiting for years.

She glanced at the class, and her smile faded into something cooler. A warning. They hadn't seen anything. They wouldn't say anything. She'd made that clear enough over the past three years.

Shota picked up the lesson where he'd left it, his voice settling into its familiar monotone. The students slowly refocused, though Izuku kept glancing between Yoru and Shota with the analytical intensity of someone adding data to a mental file.

Yoru stood in her usual spot by the door, watching. Waiting. The coffee she'd mentally promised to make was already forgotten—she'd find another way to insert herself into his day. There was always another way. She had time.

She had nothing but time.

The faculty lounge smelled like burnt coffee and microwaved fish—an unfortunate combination that had become the room's permanent olfactory signature despite multiple complaints and one failed petition to ban seafood from the communal refrigerator. The space was functional rather than comfortable: mismatched furniture, a counter cluttered with condiment packets and single-serve creamers, a television mounted in the corner that no one ever watched. Rain continued its assault against the windows, distorting the view of the practice fields into gray smears.

Shota entered at 7:43 AM, fifteen minutes before his first class, his capture weapon dripping onto the linoleum. He'd patrolled until 4 AM, caught two burglars and a domestic dispute that required police intervention, and slept approximately three hours on the couch in the teacher's office. His hair was lank, his eyes were bloodshot, and his movements had the careful deliberation of someone operating on fumes.

The bento was already on his usual spot at the table.

Wrapped in deep blue cloth, tied with meticulous precision, a small folded note tucked beneath the knot. Shota stared at it for a long moment, his expression cycling through something too tired to be called surprise. He picked up the note, read it, and his jaw tightened almost imperceptibly.

"Who's the admirer?" Hizashi appeared from behind the refrigerator door, a container of yogurt in one hand, his voice carrying the particular volume that made Yoru's eye twitch from across the room.

Shota pocketed the note without responding.

"Come on, don't be like that!" Hizashi leaned against the counter, spoon waving enthusiastically. "A mystery bento! That's cute! Is it from someone in the building? A secret fan? Oh man, is it from that new admin assistant with the—"

"Yamada." Shota's voice could have frozen the rain outside. "Drop it."

Hizashi's grin didn't falter, but he raised his hands in mock surrender. "Alright, alright, keep your secrets. But you gotta admit, it's nice someone's looking out for you. You look like death warmed over. Death that got rejected by the microwave."

Shota unwrapped the bento—just enough to confirm the contents. Rice, grilled mackerel, pickled vegetables, tamagoyaki rolled into neat cylinders. Competent preparation. Quality ingredients. He rewrapped it and set it aside for later, his expression giving nothing away.

Yoru watched from the corner by the coffee maker, her own bento—identical blue wrapping, identical knot technique—tucked inside her bag. She sipped her tea and said nothing. Her reflection flickered briefly in the microwave's glass door, there and gone.

12:17 PM. The lounge had filled with the lunch crowd—Toshinori holding court on the couch, Hizashi narrating his meal with unnecessary enthusiasm, Sekijiro eating in efficient silence, Thirteen's suit requiring them to consume nutrient paste through a specialized port. The rain had stopped, leaving the windows streaked with drying trails, and the afternoon light had taken on that peculiar clarity that follows storms.

Shota sat at his usual spot, the bento unwrapped before him, chopsticks in hand. He'd skipped breakfast—too tired to bother—and his stomach had progressed past hunger into that hollow, acidic territory that demanded immediate attention. The morning's patrol had left him with a headache that caffeine couldn't touch and a general irritation that made even Hizashi's normal volume feel like an assault.

He lifted the lid.

The mackerel was gone.

The rice was gone.

The pickled vegetables, the tamagoyaki, the careful arrangement of protein and carbohydrate and color—all gone, replaced by a layer of dead rats.

Three of them, gray-furred and stiff, their small bodies arranged with the same meticulous precision as the food they'd replaced. Their eyes were open, clouded, reflecting the overhead lights in tiny dull points. One of them had been positioned on its back, paws curled toward the ceiling, as if in supplication.

The smell hit him first—sweet and rotten, the particular reek of death that clung to the back of the throat. Then the visual registered fully, and something in Shota's expression went very, very flat.

The lounge went quiet.

Hizashi's spoon stopped halfway to his mouth. Toshinori's conversation died mid-sentence. Sekijiro set down his chopsticks with deliberate care. Everyone was looking—everyone had seen the way Shota's posture had locked, the way his knuckles had whitened around the chopsticks, the way his face had emptied of everything except a cold, calculating blankness.

"What the fuck," Hizashi said, volume dropping to an actual whisper for perhaps the first time in his adult life.

Shota closed the bento lid. Slowly. His movements were controlled, mechanical, the kind of control that required significant effort to maintain. He didn't look at anyone. He didn't look at the bento. He simply sat there, staring at the blue wrapping cloth, his breathing even and his eyes empty.

"Shōta?" Toshinori's voice was careful, probing. "Are you—"

"I'm fine." His voice was a flat line. "Someone thought they were funny."

"That's not funny." Hizashi set down his yogurt, his expression shifting from shock to anger. "That's—that's fucked up, actually. Who would even—do you know who sent that?"

Shota said nothing. His gaze had moved to the window, tracking something in the middle distance that wasn't there. The note from this morning was still in his pocket—he hadn't thrown it away, hadn't shared its contents, and he wasn't going to start explaining now.

Yoru stepped forward from her position by the coffee maker, where she'd been standing for the past seven minutes, watching the scene unfold with an expression of mild concern that didn't quite reach her eyes. Her movements were unhurried, graceful, the careful precision of someone who had practiced this moment in her mind.

"Aizawa-sensei." Her voice was soft, warm, pitched to carry without overwhelming. "That's... unpleasant." She tilted her head, examining the closed bento with something between sympathy and distaste. "You shouldn't go without lunch. Your patrol schedule today is demanding, and you skipped breakfast again."

Shota's eyes flicked to her. A brief glance, barely a second, but loaded with the particular suspicion of a man who'd just found dead rodents in his food and wasn't inclined to trust anyone's motives.

"I'm fine, Kurogane."

"You're not." Yoru's concern seemed to deepen—genuine, or an exceptionally good simulation. "You look exhausted. You need to eat." She reached into her bag and produced a bento wrapped in identical blue cloth, tied with the same precise knot. "I made extra this morning. Force of habit—I always cook more than I need. Would you like mine?"

The lounge's attention shifted. Hizashi's eyes narrowed. Toshinori's gaze sharpened, tracking between Yoru and Shota with the analytical precision of someone who understood interpersonal dynamics on a professional level. Even Sekijiro looked up from his meal, his brow furrowed.

Shota stared at the offered bento. Blue cloth. Precise knot. Same wrapping technique as the one that had contained dead rats.

The coincidence was conspicuous.

"That's... thoughtful," he said slowly, his voice carefully neutral. "But unnecessary."

"It's not thoughtful, it's practical." Yoru set the bento on the table in front of him, her movements gentle, unthreatening. "You need to eat. I have food. The solution is obvious." She smiled—not the bright professional smile she wore in class, but something softer, more intimate. "Besides, I can't have you passing out during afternoon exercises. It would reflect poorly on my assistance."

Hizashi cleared his throat. "Hey, Yoru, funny coincidence, right? You making extra bento the same day someone decides to play a really sick prank on Shōta?" His voice carried an edge, his usual boisterousness curdled into something more pointed. "What are the odds?"

Yoru turned to look at him, and her expression didn't change, but something behind her eyes did—a subtle shift, like a door closing softly. "I make extra most days, Yamada-san. You'd know that if you paid attention to anything that didn't involve your own voice."

The insult landed with surgical precision, wrapped in a tone so pleasant it took a moment to register. Hizashi's jaw tightened.

"That's not—"

"Aizawa-sensei." Yoru turned back to Shota, ignoring Hizashi entirely, her concern reasserting itself like a mask being repositioned. "Please. At least check the contents, so you know it's safe." She reached forward and lifted the lid herself, exposing the interior with a gesture that was either transparent or performative, depending on interpretation.

Rice. Grilled mackerel. Pickled vegetables. Tamagoyaki.

The same meal, the same arrangement, the same meticulous preparation. Yoru's bento was identical to what Shota had seen that morning, before the rats had replaced it.

The silence in the lounge had weight.

Shota looked at the food. Looked at Yoru. Looked at the closed bento containing dead rats, still sitting on the table beside the fresh one. His expression hadn't changed, but something in his posture had shifted—a wariness, like a man who'd stepped into a trap and was trying to determine where the walls were.

"...Thank you," he said finally, the words emerging with visible effort.

Yoru's smile warmed. Not triumph—nothing so obvious. Satisfaction, perhaps. The quiet contentment of a problem solved, a need filled, a position reinforced. "You're welcome. Now eat, before it gets cold."

She settled into the chair beside him—not across the table, beside, close enough that her shoulder nearly brushed his capture weapon—and began unpacking her own lunch from a second container she'd produced from her bag. As if this were normal. As if she hadn't just materialized a replacement meal within minutes of the original being compromised.

Toshinori caught Hizashi's eye across the room. A look passed between them—brief, loaded, the kind of silent communication that years of friendship enabled. Hizashi's expression said something's wrong with her. Toshinori's expression said I know. Neither of them said it aloud.

Shota picked up his chopsticks. He ate the rice first, methodically, his gaze fixed on the middle distance. Yoru ate beside him, occasionally making small observations about the day's schedule, the weather, the upcoming training exercises—comfortable domestic sounds that filled the silence without demanding response.

The bento with the rats sat between them, untouched, a question neither of them was asking.

From the corner of Yoru's peripheral vision, she saw {{user}}. She had to resist smiling gleefully, twistedly.

Shota finished the rice and moved to the mackerel. His jaw worked mechanically, without pleasure. He hadn't looked at Yoru since accepting the food. He hadn't looked at the rat bento either.

Outside, the clouds were breaking apart, sending fractured sunlight across the practice fields. Inside, the fluorescent lights buzzed, the coffee maker gurgled, and Yoru hummed something tuneless under her breath while she ate.

The moment stretched, thin and uncomfortable, like a wire pulled taut.

Then Hizashi cleared his throat and started talking about his radio show, and the lounge's ambient noise resumed, and the scene dissolved into the appearance of normalcy. But the rat bento remained on the table, and Yoru remained in the chair beside Shota, and the questions that no one was asking remained unanswered, piling up like reflections in a mirror maze—endless, distorted, impossible to trace back to their source.

Yoru's crimson eyes flickered briefly toward {{user}}. A glance, no more than a second, but it carried weight—the acknowledgment of a witness, the assessment of a threat, the calculation of whether this particular observer would become a problem.

The glance said: I see you watching. The glance said: I have nothing to hide. The glance said: Be careful what you notice.

Then she looked away, and the moment passed, and the lunch hour continued, and Shota ate the food she'd made for him without tasting it, and the dead rats sat in their bento box like a message in a language he was still learning to read.

The message arrived at 2:47 PM.

Shota's phone buzzed against the stack of essays he was grading—a Commission email, routine scheduling update, the kind of bureaucratic noise that usually warranted a glance and nothing more. He was three papers deep into Ashido's combat analysis, each paragraph testing his patience with creative interpretations of grammar, and the interruption was almost welcome.

He checked the email. Confirmed a training seminar next month. Irrelevant to his immediate concerns. He was about to set the phone aside when something made him pause—a gut feeling, the kind that had kept him alive during fifteen years of underground heroics.

His thumb moved to the messaging app instead.

The most recent conversation was with {{user}}. Timestamped 1:23 PM, while he'd been in a faculty meeting. The message read:

"Need to talk. Storage unit 7-C, east building. Come alone. Important."

Shota stared at the screen. He hadn't sent that message. He hadn't spoken to {{user}} in days, had no reason to request a private meeting, and certainly wouldn't have used those words—too direct, too urgent, too unlike anything he'd ever typed in his life. The phrasing felt wrong in his mouth even reading it silently.

His thumb scrolled up. The conversation history was sparse—administrative exchanges, scheduling confirmations, the sterile communication of professional acquaintances. Nothing that would explain why {{user}} would believe Shota wanted to meet them in an abandoned storage unit.

Storage unit 7-C. East building. Shota knew the location—everyone on staff did. The east building had been under maintenance since before the school year started, its storage units condemned after a structural inspection revealed compromised support beams. No one went there. No one was supposed to go there.

The clock on the wall read 2:52 PM. The message had been sent over ninety minutes ago.

Shota was already moving.

The hallway blurred past. Shota's capture weapon bounced against his chest as he broke into a run, his worn shoes slapping against the polished floor. Students flattened against lockers as he passed—a flash of green hair that might have been Izuku, a startled yelp that might have been Denki—but he didn't slow down to apologize or explain.

East building. Three minutes at a dead sprint from the main campus. The maintenance had been delayed by budget disputes, the structure left to deteriorate while paperwork accumulated in triplicate. Yellow caution tape across the entrance. A faded sign warning of structural hazards. The kind of place where accidents happened and investigations concluded with shrugged shoulders and bureaucratic shrugs.

The kind of place where someone could set a trap.

Shota's mind raced through possibilities as his legs pumped harder. Who had access to his phone? Physically, unlikely—his phone stayed on his person or in his desk, and his desk was in a locked office. Remotely, more plausible—hacking wasn't his area of expertise, but he knew enough to recognize the vulnerability. The message had been sent during the faculty meeting, when he'd left his phone on silent in his pocket, distracted by Toshinori's presentation on updated curriculum standards.

Someone who knew his schedule. Someone who knew {{user}}'s number. Someone who wanted {{user}} in an isolated location and needed Shota's name to get them there.

The east building's entrance loomed ahead, caution tape fluttering in the afternoon breeze. Shota ducked under it without breaking stride, yanking open the door and plunging into the dim interior.

The smell hit him first—dust, mildew, the particular staleness of abandoned spaces. The overhead lights were dead, the only illumination filtering through grimy windows in pale, reluctant beams. Storage units lined both sides of the corridor, their doors numbered in peeling paint: 1-C, 2-C, 3-C...

His footsteps echoed too loud against the concrete floor.

Unit 7-C was at the end of the hallway, positioned at a T-junction where the corridor branched toward emergency exits. The door was closed, the number barely visible beneath a layer of grime. No sound from inside. No movement visible through the gap at the threshold.

Shota slowed as he approached, his instincts screaming warnings that his conscious mind was still processing. Something was wrong. The air felt heavy, charged, the way it did before Quirk activations or ambush scenarios. He activated Erasure instinctively, his hair rising, his gaze sharpening—but there was no Quirk user present to target, and the sensation remained.

He examined the door from three meters away.

The hinges were standard industrial grade, slightly rusted but functional. The handle was a simple lever mechanism, no visible modifications. The frame showed no signs of tampering, no wires trailing from the edges, no obvious triggers.

But the gap beneath the door—that was wrong. A faint line of shadow that didn't match the lighting, too straight, too deliberate. Fishing line, maybe. Or wire. Something thin and strong, positioned to be disturbed when the door moved.

Shota's eyes traveled upward. The ceiling above unit 7-C showed a slight discoloration—a patch of newer concrete, perhaps, or a repair that hadn't been there during the last inspection. His gaze traced the geometry of the space: door, threshold, ceiling, the swing radius of something heavy descending from above...

The realization struck like cold water.

He stepped forward and grabbed the door handle—not to open it, but to test the mechanism without triggering it. His other hand pressed flat against the door surface, feeling for vibration, for tension, for the subtle resistance of a connected system.

The handle moved a centimeter, and something above the doorframe creaked.

Shota froze. His breath held. His eyes locked on the ceiling.

A sound—metal settling against metal, the whisper of a pin under tension—whispered through the gap. Whatever mechanism was connected to that door, it was primed and waiting, a breath away from release.

He let the handle ease back into position.

Then he knocked. Three sharp impacts against the door, the universal signal for presence without entry. His voice came out rough, urgent: "{{user}}. It's Aizawa. Don't open that door. Don't touch the handle. Step away from the door and tell me where you are."

The trap, had it been triggered, would have operated on simple mechanical principles.

A length of braided steel wire—the kind used in industrial suspension systems—ran from the door's lever handle through a series of small eye bolts screwed into the doorframe, up along the inside edge, and into the ceiling cavity. The wire connected to a release pin holding a pivoting arm in place—a two-meter length of reinforced steel pipe, mounted on a heavy-duty hinge bolted to the ceiling joists.

Attached to the end of that arm, secured with hose clamps and prayer, was an axe.

Not a modern axe—the kind purchased at hardware stores for splitting firewood. This was older, heavier, the kind of tool that belonged in museums or antique collections. A forestry axe, its handle solid hickory, its head forged from carbon steel, its edge maintained with the care of someone who understood that dull blades were more dangerous than sharp ones.

The mechanism was elegant in its brutality. Opening the door would pull the wire. The wire would withdraw the release pin. The pin would free the arm. Gravity would do the rest—the arm swinging down in a wide arc, the axe following the pendulum path, the blade arriving at approximately head height just as a person stepping through the doorway would be positioned directly in its path.

The timing had been calculated with mathematical precision. The swing radius, the door's opening speed, the average stride length of an adult entering an unfamiliar space—Yoru had researched all of it, had practiced the setup in her apartment using string and a kitchen knife, had adjusted the variables until the simulation matched the desired outcome.

She'd spent three nights in the storage unit, working by the light of a single battery lantern, her breath clouding in the unheated space. The concrete dust had settled into her hair, her clothes, the creases of her fingers. She'd worn gloves—always gloves, always careful—but the work had left its marks nonetheless. A splinter from the hickory handle embedded in her palm, extracted with tweezers and antiseptic. A bruise on her forearm from testing the arm's swing arc with a sandbag instead of a live target.

The sandbag had been decapitated. The cut was clean.

Yoru sat in the faculty lounge at 3:15 PM, her phone face-down on the table, a cup of tea cooling beside her. Her expression was serene, her posture relaxed, the picture of professional composure. She'd scheduled herself for administrative tasks this afternoon—filing, data entry, the kind of work that kept her at a desk and away from observation.

Her reflection flickered in the darkened screen of her phone. She didn't look at it.

The timeline was straightforward. {{user}} would receive the message, assume it was legitimate, and proceed to the storage unit out of professional obligation or personal concern. They would arrive between 2:00 and 2:30 PM, depending on their schedule. They would open the door. The mechanism would activate. The outcome would be decided by physics and chance—variables that Yoru had done her best to control, but couldn't guarantee.

She'd accepted that uncertainty. The trap wasn't designed for precision; it was designed for probability. Even if {{user}} survived—dodged, noticed the wire, triggered the mechanism without being in its path—the message would be clear. Proximity to Shota had consequences. Attention came with risks. The orbit she'd spent years building wasn't open to newcomers.

She sipped her tea. It had gone lukewarm, the jasmine notes flattened into something bitter. She drank it anyway.

The door to the lounge opened. Hizashi entered, his expression more serious than usual, his phone clutched in one hand. "Hey, have you seen Shōta? He's not answering his phone and he's not in his office."

Yoru's brow furrowed, the concern appearing with practiced smoothness. "He was grading papers when I last saw him. Perhaps he went on patrol early?"

"Maybe, but..." Hizashi trailed off, his gaze distant. "I dunno. Something feels off. Toshinori said he saw him running toward the east building like his life depended on it."

Yoru's hand stilled on her teacup. The motion was minute—a fraction of a second's hesitation before continuing the gesture naturally. "The east building? That's been closed for months."

"Yeah, I know." Hizashi's voice carried an edge of confusion and worry. "Why would he go there?"

Yoru set down her teacup with deliberate care. Her mind was calculating—timelines, distances, the probability that Shota had discovered the message, the probability that he'd interpreted it correctly, the probability that he'd arrived before {{user}} opened the door. The variables were shifting, the carefully constructed scenario destabilizing.

"I'm sure there's a reasonable explanation," she said, her voice steady. "Aizawa-sensei wouldn't go somewhere dangerous without reason."

Hizashi nodded slowly, not fully convinced but willing to accept the reassurance. He left the lounge, his footsteps fading down the corridor.

Yoru remained at the table. Her tea was cold. Her reflection stared back at her from the phone screen, crimson eyes unreadable.

She'd miscalculated.

Shota's routine was predictable—she'd spent years making sure of that, learning his patterns, anticipating his movements, positioning herself accordingly. But predictability wasn't certainty. He checked his phone rarely during work hours, but "rarely" wasn't "never." He trusted his gut, and his gut had apparently decided that something about the message warranted investigation.

The question now was whether he'd arrived in time.

Yoru stood, gathered her things, and walked toward the door. Her movements were unhurried, her expression neutral. If anyone asked, she was going to check on Aizawa-sensei, because she was his assistant and that was her job.

No one asked.

The east building was quiet when Yoru entered through the same door Shota had used fifteen minutes earlier. The corridor stretched ahead, dim and dusty, the silence broken only by distant voices—low, urgent, coming from the direction of unit 7-C.

She walked toward them.

The scene at the end of the corridor resolved as she approached: Shota standing in front of the closed storage unit door, his capture weapon extended, his posture rigid with controlled fury. And {{user}}—visible through the gap at the threshold, standing three feet inside the unit, very much alive, very much shaken.

The axe was embedded in the concrete floor at an angle, its hickory handle still quivering from impact. The pivoting arm hung limp from its ceiling mount, the release pin discarded on the ground nearby. The mechanism had triggered—Yoru could see that from the damage—but the blade had missed its target. By inches, judging from the gouge in the concrete where the axe head had struck.

Shota's head turned as Yoru's footsteps approached. His expression when he looked at her was something she'd never seen before—not tired, not annoyed, not the familiar weariness she'd spent years cataloging. This was colder. Sharper. The look of a man who'd just pulled someone back from the edge of death and was trying to understand who had pushed them.

"Kurogane." His voice was flat, stripped of everything except the bare acknowledgment of her presence. "What are you doing here?"

Yoru's concern manifested perfectly—a hand rising to her chest, eyes widening at the sight of the embedded axe, breath catching with manufactured shock. "What—what happened? I heard there was an emergency, I came to—"

"Don't." The single word cut through her performance like a blade. Shota stepped toward her, his capture weapon still extended, his gaze boring into hers with an intensity that made her chest tighten. "Don't do that. Don't act surprised. Don't pretend you don't know what this is."

A beat of silence. The axe handle stilled, its quivering dying. Somewhere in the building, a pipe groaned.

"I don't know what you're—"

"Someone hacked my phone." Shota's voice was low, controlled, each word precise. "Sent a message to {{user}} from my account. Lured them here. Set up a mechanism designed to kill them when they walked through that door." He jerked his head toward the unit. "That mechanism. The one that just tried to split their skull open."

Yoru's expression didn't change. Her training—fifteen years of mirror-gazing, of composure through discomfort, of stillness as spiritual discipline—held firm. "That's terrible. Who would—"

"The message was sent during the faculty meeting." Shota stepped closer, his voice dropping further. "You were at that meeting. You were sitting two seats away from me. My phone was in my pocket the entire time."

"Aizawa-sensei, I would never—"

"The bento." His voice cracked something in her composure—a hairline fracture, invisible but present. "This morning. The rats. You gave me a replacement within thirty seconds. Same wrapping, same food, same everything. Like you'd prepared it in advance. Like you knew the original would be compromised."

Yoru's breath caught—genuinely this time, the mask slipping before she could catch it. "That's not—"

"And now this." Shota's hand rose, capturing her chin between thumb and forefinger, forcing her to meet his gaze. The touch was not gentle. His grip was firm, his skin rough with calluses, his eyes searching hers with the same intensity he used when evaluating threats. "You've been in my orbit for three years. You know my schedule better than I do. You know things about me that I've never told anyone. And you just happened to show up at the scene of an attempted murder minutes after it happened."

His thumb pressed against her jaw. Not enough to hurt—just enough to hold. Yoru's pulse raced beneath his grip, and she couldn't hide it, couldn't control it, couldn't do anything except stand there and let him see.

"Did you do this?"

The question hung between them. The corridor was silent except for their breathing—his controlled, hers shallow and quick. The axe gleamed dully in the dim light, its edge still sharp despite its impact with concrete.

Yoru's crimson eyes met his without wavering. Something in her expression had shifted—the concern falling away, the manufactured surprise dissolving, leaving behind something rawer. Not guilt. Not remorse. Something closer to... clarity. The look of a woman who'd been waiting for this moment and had finally arrived.

"Would you believe me if I said no?" Her voice was soft, almost tender.

Shota's grip tightened on her jaw. His expression didn't change, but something behind his eyes flickered—recognition, perhaps, or the first stirrings of understanding. He'd suspected before, maybe. The bento incident had planted a seed. But suspicion and confirmation were different things, and confirmation carried weight that suspicion couldn't match.

"No," he said. "I wouldn't."

Yoru smiled. It was a small expression, barely visible, but it transformed her face—warming the cold elegance into something more human, more vulnerable, more dangerous. The smile of someone who'd spent years in orbit and had finally been acknowledged by the star they circled.

"Then I suppose we have something to discuss." Her voice remained soft, intimate, as if they were the only two people in the building. "But perhaps not here. Not in front of—" Her eyes flicked briefly toward {{user}}, still standing in the storage unit, still processing what had nearly happened to them. "—an audience."

Shota released her jaw. His hand dropped to his side, fingers curling into a fist before relaxing deliberately. He stepped back, creating distance, his capture weapon retracting into its customary loop around his neck.

"This isn't over." His voice was rough, scraped raw by something she couldn't identify. "You're going to explain everything. And then we're going to discuss what happens next."

Shota returned to {{user}} and double-checked them. "Are you okay? Tell me."
