The door to Class 1-A was massive, a heavy slab of reinforced metal that felt more like a fortress gate than a classroom entrance. Izaya Kurogane took a silent, centering breath. Behind this door was the beginning of everything. He could feel the hum of activity from within—a cacophony of overlapping voices, a kinetic signature of twenty young individuals brimming with power and personality. It was a complex, chaotic piece of music, and he was about to step onto the stage.
He slid the door open.
The room fell into a momentary hush as twenty pairs of eyes turned to him. He stood in the doorway, his posture relaxed but not slouching, his expression one of calm observation. He met their gazes for a second, taking them in—the vibrant colors, the unique physiques, the sheer potential radiating from each student.
A boy with neatly combated blue hair and glasses shot up from his seat, chopping the air with robotic precision. "Good morning! I am Tenya Iida from Somei Junior High! You are precisely on time! A commendable start to your U.A. career!" His voice was loud and formal, cutting through the lingering silence.
Izaya gave a slight, polite bow of his head. "Izaya Kurogane. It's good to meet you." His voice was quieter than Iida's, but it carried easily in the room. He moved towards the empty seat, which happened to be behind a boy with a familiar head of spiky, blond hair that smelled faintly of nitroglycerin—Bakugo. He remembered him from the exam. The human explosion.
As Izaya sat, the boy in front of him, a green-haired kid with a constellation of freckles, turned around with a nervous, but bright smile. "Oh! Uh, hello! I'm Izuku Midoriya! That was really amazing what you did in the entrance exam!"
Before Izaya could respond, a bubbly voice piped up from beside Midoriya. A girl with round, pink cheeks and a friendly smile leaned over. "Yeah! You were the one with the cool staff, right? And you made that giant robot trip! That was so brave! I'm Ochaco Uraraka!"
The mention of the exam seemed to open the floodgates.
"A staff, you say?" mused a tall, elegant boy with blonde hair and a peculiar navel laser. "A most noble and classic weapon. I am Yuga Aoyama! I, too, understand the importance of a dazzling presentation!" He struck a subtle sparkly pose.
From a few seats over, a redheaded boy with sharp teeth slammed his hands on his desk, a wide grin splitting his face. "That was so manly! Running right at that thing! I'm Eijiro Kirishima! Your quirk is like, total matter control, right? So hardcore!"
A girl with pink skin and hair bounced in her seat. "Whoa, for real? You can, like, make stuff out of other stuff? That's almost as awesome as my Acid! I'm Mina Ashido! We're gonna have so much fun!"
The chatter began to overlap, a lively, chaotic symphony.
"A logical application of a versatile quirk," noted a bespectacled girl with a black bob, adjusting her hair. "I am Momo Yaoyorozu. Your ability to deconstruct and reconstruct non-living matter on the fly is remarkably efficient, albeit on a different scale than my own Creation."
A boy with multiple, smaller arms emerging from his face gave a friendly wave. "It's super handy! I'm Mezo Shoji. Your control must be incredible."
A tiny, perky girl with large hands who seemed to be vibrating with energy popped up. "It's like super-advanced origami! But with, like, everything! I'm Toru Hagakure! You can't see me, but I'm waving!" A floating glove indeed waved enthusiastically from her desk.
Izaya found himself at the center of a whirlwind of introductions. He answered questions with simple, polite nods and short answers, carefully curating his responses.
"It's primarily tactile-based," he said to Yaoyorozu. "I need to be in contact with the base material to break it down."
"Thanks," he said to Kirishima, offering a small, genuine smile. "It's less about power and more about knowing where to apply pressure."
He noticed a boy with a raven's head, shrouded in a palpable aura of gloom, who simply muttered, "A power born of light, to weave the dust of a decaying world... intriguing." This was Fumikage Tokoyami.
A large, muscular boy with a stern face simply said, "Rikido Sato." before offering a quiet, "Your martial arts form was good."
A girl with earphone jacks hanging from her lobes gave him a lazy, appraising look. "Kyoka Jiro. Nice moves. The music during that fight would've had a great rhythm." She tapped her jack against her desk lightly.
A boy with a long, lightning-bolt streak in his hair vibrated with energy. "Denki Kaminari! Dude, that extending staff thing is epic! Way cooler than just shooting electricity!"
A girl who seemed to be half-human, half-animal with feline features smiled shyly. "I'm Tsuyu Asui. But you can call me Tsu. Ribbit. It was very clever, how you used the environment."
A boy with a tall, stiff collar covering most of his face bowed his head slightly. "Koji Koda." he whispered, almost inaudibly.
Momo Yaoyorozu then said with a warm, confident smile. "Looks like we've got another strategist in the class. Looking forward to working with you."
The only one who remained completely silent was a boy with heterochromatic eyes and a red-and-white split of hair, Shoto Todoroki. He didn't turn around. He didn't speak. He simply stared ahead, a glacier of quiet intensity, completely detached from the social current flowing around him.
Midoriya, meanwhile, had descended into a familiar muttering storm, his notebook seemingly materializing out of nowhere. "The staff's composition is clearly particulate matter held in a forced cohesion, which suggests incredible fine control over molecular kinetic energy, or perhaps a form of telekinesis specific to inanimate matter? But the redirection of the zero-pointer's foot... that was a macroscopic kinetic transfer, which is a completely different order of magnitude! Could it be that his 'Matter Manipulation' is actually a subset of a broader energy manipulation quirk? The potential applications are—"
"Will you shut up, you damn nerd!" Bakugo suddenly snarled, not even turning around, but his voice cracking through the room like a whip. "He's not some specimen for you to drool over! He just got lucky with a flashy trick!"
The room quieted for a beat. Izaya looked at the back of Bakugo's head. There was no anger in his gaze, only analysis. Bakugo's aggression was a form of motion, predictable and volatile.
"He wasn't lucky, Bakugo," Uraraka said, frowning. "He saved that girl."
"Tch. Whatever. He still didn't beat the thing. Just made it look stupid," Bakugo grumbled, slouching lower in his seat.
Kirishima laughed, breaking the tension. "Come on, man, don't be like that! It was seriously manly!"
The conversation began to flow again, shifting to other topics—the size of the classroom, who the homeroom teacher might be, speculations about the other students from the exam. Izaya listened, a quiet island in the stream of chatter. He was mapping them. Iida was order and structure. Midoriya was analysis and passion. Uraraka was warmth and empathy. Bakugo was raw, unchecked power. Yaoyorozu was intellect and grace. They were all individual instruments, and he was learning their unique sounds.
He felt a strange sense of belonging, yet remained apart. These were his classmates, his future colleagues. But he couldn't share his true self with them. Not yet. Perhaps not ever.
Just as Ashido was asking Aoyama if he could cook with his navel laser, the door slid open again with a quiet shhhhk.
A disheveled man in a black jumpsuit, wrapped head to toe in a dirty yellow sleeping bag, crawled into the room. He stood up, unzipping the bag to reveal a gaunt face with tired eyes and a capture weapon looped around his neck.
"It took eight seconds for you all to shut up. That's eight seconds too long. Time is a precious resource. You lot are not rational enough." His voice was a flat, dry monotone that instantly sucked the energy from the room. "I'm your homeroom teacher, Shota Aizawa. Pleased to meet you."
He pulled a blue and white gym uniform from his sleeping bag. "Right. Change into these and meet me on the P.E. grounds in five minutes. We're starting a Quirk Apprehension Test."
A stunned silence followed. A Quirk Apprehension Test? On the first day? What about the entrance ceremony? Guidance sessions?
As the class erupted in confused murmurs, Izaya's calm exterior didn't flicker, but internally, his senses sharpened. This was it. The first real test of his deception. Aizawa's tired eyes scanned the room, and for a fleeting moment, they seemed to linger on Izaya.
The symphony was over. It was time for the solo performance.
