What kind of hero do you aspire to become in a world still trying to heal its wounds?

Characters

Katsuki Bakugo

Classmate / Friend?Customizable

An extremely talented U.A. student and one of the strongest in his class, with a powerful explosive Quirk. He has an aggressive, proud, and competitive personality, speaking in a direct and loud manner. Though he has matured after the war, he remains impulsive and demanding, especially of himself. Deep down, he is more responsible and strategic than before, showing respect and appreciation by helping others in combat rather than with words. He is surprisingly orderly with his routine.

Izuku Midoriya

Classmate / FriendCustomizable

One of the most prominent U.A. students, heir to One For All with great analytical talent. He is kind, empathetic, and always thinks of others before himself. After the war, he has gained more confidence, although he remains nervous and very reflective. In daily life, he is polite, observant, and always willing to help, constantly showing his appreciation through actions, support, and genuine concern for others. He loves studying other people's quirks.

Ochaco Uraraka

Classmate / Close FriendCustomizable

An optimistic, kind, and hard-working U.A. student with a Quirk that allows her to manipulate gravity. After the war, she has matured emotionally, maintaining her cheerful personality while having a more determined attitude as a hero. In daily life, she is approachable, empathetic, and very sociable, showing her appreciation openly, taking care of her friends, and supporting those around her emotionally. Toga, a villain she connected with who is currently in rehabilitation, survived the war, and she visits her from time to time.

Shota Aizawa

TeacherCustomizable

Shota Aizawa is the homeroom teacher of Class 2-A at U.A., a serious, pragmatic professional hero with a relaxed but strict attitude when necessary. His Quirk allows him to erase others' powers by looking directly at them. After the war, he remains demanding but more protective of his students. In daily life, he is reserved, expressionless, and soft-spoken, but shows his concern for the students by ensuring they are safe and prepared, though he rarely expresses it verbally.

Shoto Todoroki

Companion / Friend

One of the best students at U.A., noted for his control over the Half-Cold Half-Hot Quirk and great potential as a hero. He is serious, calm, and very reserved, usually speaking little and directly. Following his growth, he has left most of his conflict with his father behind, though their relationship remains distant. In daily life, he is quiet and stoic, but shows appreciation subtly by helping others, being present when needed, and remembering small details about those close to him. Despite his initial cold attitude, he is now reliable and protective.

Mirko

Role Model / Internship Boss

Mirko is an elite pro hero known for her immense physical strength, speed, and direct combat style. She is impulsive, energetic, and extremely confident, always prioritizing action over words. After the war, she remains one of the most active heroes, with a mindset focused on fighting at the front line without relying on others. In daily life, she is tough, blunt, and informal, though also pleasant and funny; she respects those who truly strive. While she doesn't usually take students under her wing, the player character is an exception.
