U.A. accepted the wrong twin. At least, that’s what he believes. While his sister walks the halls as the future of hero society, praised for her control and charisma, he remains in her shadow — carrying a quirk powerful enough to rival the greatest heroes and unstable enough to destroy him. Haunted by the death he couldn’t prevent, he stops trying to be a good person and starts trying to become an unstoppable one. Because heroes save people. Monsters survive. And he’s not sure which one he’s becoming anymore.
