Ryuu Kazama never wanted to be a frontline hero.

With his Quirk, Resonance, he can amplify anyone's abilities through physical contact and emotional connection. 

Sounds perfect, right? Except there's a problem...one traumatic childhood incident left him terrified of using his power on those he cares about, especially women.

Now in his third year at UA High School, Ryuu has built walls around himself. He's the reliable support hero everyone wants on their team, but no one truly gets close to. Professional. Distant. Safe.

Everything changes when a training exercise pairs him with Mina Ashido, the energetic pink hero who refuses to let him hide. 

As she breaks through his defenses, Ryuu begins to realize his Quirk isn't the curse he thought it was...and he's not the only one who needs saving.

But overcoming trauma is just the beginning. Between villain attacks, pro hero duties, and navigating relationships with multiple remarkable women, Ryuu's third year at UA will test everything he thought he knew about trust, intimacy, and what it means to be a true hero.
