Chapter Text
The morning sun poured through the blinds in slanted gold beams as Rumi Usagiyama stood in front of the mirror inside her dorm. Her room was still mostly undecorated—only a few personal touches like her old school track medal and a framed photo of her and Kaine at last year's school festival had made it out of their moving boxes. She stared into her reflection, focused, dragging the straightener through her silver-white hair with mechanical precision. Her ears twitched lightly as the heat passed near them.
She set the straightener down, let out a breath, and gave herself a nod.
Rumi: Alright. First day. Don't screw it up.
She slung her backpack over her shoulder, checked the zippers twice—notes, notebooks, pencil case, water bottle—and gave one last look around the room before heading for the door.
Just as she opened it, the door to her right clicked open too.
Out stepped Kaine Parker, adjusting the collar of his uniform jacket. His hair had that usual messy volume that made it look like it styled itself. His eyes caught hers and the two froze for a beat, surprised and perfectly timed.
Rumi: We've got to stop meeting like this.
He looked her over, not shy about it. A soft smirk crept onto his face.
Kaine: Why stop now?
He took a step closer, reached over, and brushed a tiny strand of hair from her cheek.
Kaine: You look perfect.
Her face warmed as her ears dipped, and she glanced away with a small smile, kicking the floor with the tip of her shoe.
Rumi: Tch... you're so cheesy.
But she reached out her hand anyway. He took it without hesitation.
They walked together through the dorm hallway, their hands gently swinging in rhythm, the buzz of other students waking up and rustling through their own routines trailing in the distance.
Rumi: I'm glad he's here. He could've been at U.A. right now, in the fast lane to fame and big-name mentors... But he chose this. He chose me.
She turned her eyes up at him as they walked, but Kaine was just admiring the architecture of the school ahead—an elegant blend of tradition and modern design, with tiled rooftops sloping into sleek glass halls. The buildings loomed taller as they neared, not as pristine or flashy as U.A., but bold in their own right. A mural of Japan's greatest pro heroes stretched along one courtyard wall, paint still fresh from the summer renovation.
Rumi: I don't know if I'll ever be able to repay him for that choice... but I'll try.
Their feet clicked against the stone path, echoing faintly. Birds chirped overhead. A few upperclassmen passed them on their bikes, nodding politely. The moment felt like something out of a quiet movie—nothing too flashy, just the two of them, grounded in the morning calm.
Eventually, they stopped in front of a polished wooden door with the plaque: Class 1-A
They both stared at it for a second.
Rumi: Well... here it is.
He exhaled.
Kaine: It's finally here.
They stepped in.
The classroom was already partly filled. Sunlight poured through the tall windows, casting warm light across the clean rows of desks. The room smelled faintly of fresh wax and chalk. Students chatted quietly, some sitting in groups, others still standing and sizing each other up.
Near the back, Ryuko Tatsuma sat on top of a desk, legs crossed, tossing a pack of gum between her hands. She wore the uniform loose and carefree, like she owned the place.
Next to her stood Taishiro Toyomitsu, already halfway through a rice ball, and Keigo Takami, leaning back in his chair with his feet kicked up against another desk.
Ryuko: Did you guys see that clip of All Might's fight yesterday? Dude launched himself like fifty feet into the air.
Taishiro: And still made the catch!
Keigo: I don't really catch up on All Might's fights, to be honest.
Rumi and Kaine joined their friends at the back, sliding into the familiar dynamic like it never left.
Kaine: That's only cuz he's a diehard Endavor fan.
Keigo: Like you're one to talk.
Kaine: I know, but I don't slander All Might like you do.
Toyomitsu offered a warm grin.
Taishiro: Yo. You guys ready?
Kaine leaned on the desk beside Rumi, their hands still brushing lightly now and then.
Rumi: So what do we think? Training drills first on the day? Or some boring intro lectures?
Keigo: Place your bets, folks. I'm thinking a fake villain ambush to test our nerves.
Ryuko: My money's on boring intro lectures.
Taishiro: Maybe we're doing a campus tour?
Kaine: I'm with birdboy, villain ambush.
A few more students had entered, murmuring among themselves, exchanging nervous glances, clutching notebooks. The energy was a mixture of excitement and tension—like everyone was aware that this place was going to change them.
The bell rang.
Everyone hurried to their seats. Rumi and Kaine slid into the same ones they always had back in middle school—fifth row from the back, near the window. Rumi's chair squeaked faintly as she pulled it in. Outside, the wind stirred the trees, casting flickering shadows into the room.
She turned toward the front as the door opened, revealing their homeroom teacher stepping in with a stack of papers and a commanding aura.
She sat up straighter, her heart steady.
Rumi: Let's do this.
~~~
The heat clung to the skin, sunlight unfiltered and bright against the school's wide-open field. The turf was warm underfoot, the lines freshly painted, cones set, and every station lined with tools and tech meant to measure strength, speed, power, and control. No one spoke. The sound of effort carried more meaning—sneakers grinding against ground, labored breathing, the snap of movement against wind.
Rumi stood at the starting line. She rolled her shoulders once, crouched low, and launched forward. Her legs exploded beneath her, and the track flew past in a blur. Her hair streamed behind her, ears flat from the wind pressure, eyes focused dead ahead until the dash ended with a sharp, clean stop.
Not a second later, Kaine's run followed. His footfalls were quiet, calculated, his figure a streak across the lane. He cut through the air with a strange grace, clean and fast. He finished just ahead.
They reset for the next. Long jump. Rumi's legs coiled, and she sprang, soaring over the pit with tight form and a solid landing. She stepped out of the sand with a flick of her ear, gaze already tracking the next result. Kaine landed a few paces beyond hers, barely leaving a mark in the pit. No theatrics, just distance.
The rest of the class moved in waves. Keigo's wings flared wide during nearly every test, using momentum to carry himself through dashes and lifts. He skipped across the field like a hawk in open sky, all speed and instinct. Ryuko dug into the ground with every movement, her power showing in the depth of her landings and the way mats curled slightly under her feet. She didn't care for subtlety. It was all raw muscle and control.
Taishiro lagged during the sprints. Every run looked like he was dragging something behind him. But he planted himself firmly for the grip test. The metal protested in his grasp, veins visible across his forearms. During the ball throw, his stance barely shifted, but the ball vanished into the distance with a sound like thunder. He lifted weights as though they were props, simple extensions of his body.
Each student carved their strengths into the data without a word. The test kept moving.
Side-step dash. Kaine slipped between cones with almost no sound, movements barely there. Rumi's bursts were more direct, each push controlled, launching her from one point to the next. Her muscles strained, the burn of repetition creeping up her spine. She knew she was near the top, but not always at it.
Ryuko slammed through the course with speed and grit, boots dragging into the turf with loud, rough turns. Keigo dipped and fluttered, nearly skipping the exercise entirely with his quirk, but he kept within the parameters. Taishiro brought up the rear, his movements powerful but clumsy in tight maneuvers.
By the end of the day, the group stood in scattered silence along the field's edge. Some sat on the grass, chests rising and falling slowly. Others stood with hands on hips or knees, sweat clinging to brows and collars.
There were no speeches. No rankings. No explanations.
But everyone knew.
Who was fast.
Who was strong.
Who needed more time.
And it was only the first day.
~~~
The sky outside the dorm windows had shifted to a deep amber, casting a soft orange glow across the polished floors and high ceilings of Isamu Academy's dormitory. The hum of the elevator echoed for a moment before its doors slid open on the first floor. Taishiro stepped out, his shoulders slightly slouched with the weight of the day's exhaustion. The quiet of early evening wrapped around the building like a warm blanket.
He made his way toward the kitchen, his steps soft against the tile, and as he turned the corner, his eyes landed on Ryuko.
She sat at the kitchen countertop, back slightly hunched, pen tapping the side of a worksheet. Her earbuds were in, one leg bouncing slowly beneath her stool. A textbook lay open beside her tablet, screen dim but glowing faintly with an assignment prompt. Her hair fell loose down her back, catching the light of the setting sun in uneven streaks.
Taishiro paused at the entrance, then continued without a word. The fridge gave a quiet creak as he opened it. Ryuko glanced up, catching sight of him from the corner of her eye, but didn't stop writing. Her focus remained fixed, eyes flicking between notes and tablet screen.
He pulled out some sliced turkey, cheese, and a loaf of soft white bread, working methodically as he built a simple sandwich. The silence between them was easy, not awkward, filled with the ambient clicks of keys and the distant wind brushing the windows.
With the sandwich finished, he turned slightly, watching her still scribbling, focused. He blinked once, then turned back, rinsed two apples under the tap, and began slicing them on the cutting board. The crisp sound of blade meeting fruit was rhythmic, steady.
When the slices were neatly arranged, he placed them on a plate and slowly slid it across the counter, stopping just at the edge of her notebook. Her hand paused mid-word. She looked at the plate, then up at him.
Taishiro offered a small, genuine smile. Nothing more.
She pulled out one earbud and raised her brow slightly.
Ryuko: Thanks.
Taishiro nodded, then tilted his head a bit.
Taishiro: Is that Crimson Tides?
She blinked.
Ryuko: Yeah... they're not super big or anything, but I like them.
Taishiro: I've got their album upstairs. The red one with the white swirl cover.
Her expression shifted, amused. She leaned back a bit, arms crossing loosely as she rested one elbow on the counter.
Ryuko: Wait... you're into music like that?
He shrugged with a small grin.
Taishiro: Been listening to them since middle school. I like the way they blend synth and bass without overdoing it. Feels... grounded.
She nodded slowly, the corner of her mouth tugging up.
Ryuko: Huh. Thought you were more into, like, ambient study playlists or something.
He chuckled quietly, scratching behind his ear.
Taishiro: I do that too... but Crimson Tides helps me zone in. Especially their live sets. That raw energy?
Ryuko: The guitar solo on Autumn Static? It's ridiculous. Like, it builds up for nearly two minutes, then just lets loose.
Taishiro: That track got me through finals last year. Played it on loop while reviewing case law examples.
She gave a small laugh, more genuine now, her shoulders relaxing.
Ryuko: You're full of surprises, Toyomitsu.
He offered a calm nod, voice lower.
Taishiro: People don't usually ask.
They sat in that silence for a bit, not heavy, just shared. The apple slices slowly disappeared between them. The sun continued its slow descent, the kitchen lights overhead flickering on automatically as the natural light dimmed.
She adjusted the volume on her tablet and nudged the plate a little closer to him.
Ryuko: You ever go to any of their shows?
Taishiro: Not yet. But if they come to Hiroshima again... I'm there.
She smiled again, softer this time.
Ryuko: Might have to go with you. Be nice to know someone else shouting the lyrics.
The thought made him nod again, quietly pleased.
Taishiro: Yeah. I'd like that.
~~~
The light outside had turned amber, casting a warm glow against the walls of Rumi's dorm. The sky was layered with soft purples and golds, the kind of sky that made everything inside feel still and suspended. Her desk lamp was on, casting a circle of light over their homework. The rest of the room was dim and quiet. A breeze through the open window fluttered a page on her notebook.
Rumi sat forward, elbow resting on the desk, brow furrowed as she tapped her pencil against the margin of a worksheet. Kaine sat to her right, slightly leaned back in his chair, one leg resting over the other, posture relaxed but his eyes focused on her. He watched the way her hand moved as she wrote, the little flick her pencil made when she got stuck on a word.
Rumi: Wait... this part. The agency collaboration clause. Does it mean sidekicks can be loaned out?
Kaine shifted slightly, eyes flicking to the line of text.
Kaine: Sort of. It's more like a temporary merge between two agencies. Usually when there's a multi-district threat. Sidekicks, interns—anybody below lead rank—can be reassigned if both agencies agree.
Rumi nodded slowly and underlined the sentence in her notes. Her rabbit ears flicked once, reacting to the sound of his voice.
That was when Kaine's gaze lingered again. He'd seen them twitch before, usually when she was focused or annoyed. But now, sitting this close, with the soft lamp light catching their outline... he couldn't help but watch them. Not in a mocking way, not with any plan. Just curiosity.
Kaine: They look so soft...Would they feel like a cat's ear? Or something different? She'd kick me in the jaw if I just reached out without asking.
So he didn't. He just stared.
A moment passed.
Then another.
He didn't notice how quiet he'd gotten, how still—until her fingers brushed his hand. It was a gentle tap, enough to snap him out of it.
She turned slightly, brow raised.
Rumi: You good?
He blinked, shifting upright in his chair.
Kaine: Yeah—sorry. Zoned out.
She tilted her head, eyes narrowing just a little.
Rumi: You never zone out. What were you thinking about?
He hesitated. His hand went to the back of his neck.
Kaine: ...Nothing. Let's just finish the—
She leaned in, not letting him off the hook.
Rumi: Kaine.
He looked at her. The way she stared made it impossible to lie.
Kaine: I was wondering what your ears feel like.
That made her pause. Really pause.
One ear tilted sideways. Her expression shifted from confusion to realization.
Rumi: ...Huh.
She reached up and brushed her fingers against one ear, casually, like someone tugging a sleeve.
Rumi: I guess not everybody would know.
She looked away, chewing her lip for a second, clearly thinking something over. Then her voice dropped a little, quiet, hesitant.
Rumi: You can touch them. If you want.
His eyes widened slightly. He turned his body to face her more directly, reading her expression carefully.
Kaine: Are you sure?
She nodded, not meeting his eyes this time.
Rumi: Just... be gentle.
He reached out slowly, lifting his hand like he was approaching something sacred. His fingers touched the edge of her ear—just barely brushing it—and it was like nothing he expected. Softer than anything. Warmer too. Like the fur of a newborn animal, or the inside of a brand-new hoodie, but somehow... better. Real.
He moved along the curve, tracing its length with care.
Her breath caught. Her body tensed—not in fear, but anticipation.
Rumi didn't say a word. She didn't need to. Her eyes were wide and locked ahead, not on him. Her lips parted just slightly, trying to keep a sound from escaping.
He pulled back for a moment.
Kaine: ...Can I try the inside?
Her blush deepened. She hesitated. Then gave a small nod.
He reached again, slower this time, and brushed his fingers inside, barely grazing the inner fold. The reaction was instant. Rumi's whole body jolted slightly, a quiet, restrained noise caught in her throat. Her hand gripped the edge of the desk.
She turned suddenly, red-faced.
Rumi: Okay, that's enough!
He pulled back immediately, blinking in surprise. His heart was still racing from the intensity of it. But before he could apologize—
She stood. And then, without a word, climbed into his lap, straddling him, knees settling against the sides of his chair.
His breath caught. Her arms went around his neck, and now she was so close—so close he could see every line of her expression. Her eyes didn't waver.
Rumi: You can't be the only one who gets to enjoy himself.
Kaine: ...What do you mean?
Her voice was lower now. Barely above a whisper.
Rumi: I want to kiss you. For as long as I can.
And then she leaned in.
Her lips found his in a rush—no pause, no testing the waters. Just warmth and motion. Her kiss wasn't slow or cautious like the others had been. It was deep. Fierce. Her mouth moved with hunger, like every ounce of tension from the last few minutes had exploded all at once.
He responded in kind.
Kaine's arms wrapped around her waist, pulling her closer, tilting his head to meet her rhythm. Their bodies pressed together, heat rising between them. Her hands tangled into his hair. Their noses bumped briefly before they found a better angle.
It was messy. Breathless. But neither of them stopped.
Rumi leaned in harder, kissing him like she couldn't get enough. His hands held her tighter, his lips moving just as eagerly. When her tongue finally brushed his, the sensation sent a spark straight down his spine.
She moaned against his mouth—quiet, but real. Honest.
Time didn't matter.
The only sound was the soft, breathy rhythm of their mouths, the creak of the chair under their weight, and the fading wind outside the window.
