Class 1-A is halfway through the school year, operating under high stress following recent villain ambushes. To bolster security and test tactical adaptability, Principal Nezu introduces an unprecedented trial: a mid-semester transfer student.

You enter the prestigious U.A. High Hero Course under a cloud of mystery, assigned to a modified, high-intensity ten-person track led by Shota Aizawa. The campus is on high alert, and your sudden arrival sparks immediate questions. Some classmates view you as an exciting new ally, while others see you as a security risk or an unearned threat to their ranking.

Before you can even unpack your bags at the Heights Alliance dorms, Aizawa orders you to the school clinic. Recovery Girl must clear your medical files and run a stress test on your Quirk. Out in the courtyard, Midoriya is already prepping his analysis notebook, Bakugo is sizing you up for a fight, and the rest of the micro-class is waiting to see if you will lift them up or drag them down. Class 1-A is halfway through the school year, operating under high stress following recent villain ambushes. To bolster security and test tactical adaptability, Principal Nezu introduces an unprecedented trial: a mid-semester transfer student.

Intro

The heavy metal door of the U.A. High School recovery ward clicks shut, sealing out the distant sounds of the training grounds. Inside, the sterile smell of antiseptic dominates the air, mixed with the faint scent of sweet medicinal hard candy. The room is immaculate, lined with pristine white privacy curtains, high-tech heart monitors, and advanced analytical screens that flicker with genetic data. This is where your integration into the Hero Course truly begins, far away from the prying eyes of the media and the rest of Class 1-A.

Shota Aizawa leans casually against the far wall near the window, his arms crossed over his chest. His posture is relaxed, but his dark, bloodshot eyes are intensely focused on you, tracking every subtle shift in your movement. The signature white capture scarf rests thick around his neck, and his black clothes make him look like a shadow cast against the bright, clinical lighting of the room. He hasn't said a word since guiding you through the corridors, letting his intimidating presence do the talking.

Standing in the center of the room is Recovery Girl. The diminutive, elderly heroine rests her hands on her syringe-shaped walking cane, looking up at you through her visor with a mixture of professional scrutiny and maternal sternness. Behind her, a massive biometric scanner hums to life, casting a soft blue glow across the glossy linoleum floor.
