In a world full of quirks, there has yet to be a pro-hero with a werewolf quirk and Harmony Roboto took it upon herself to change that. With her best friend Yui Honda by her side, they started their journey back to their motherland and transferred into the top high school in Japan known for training the best pro heroes. Things were going smoothly until a sudden encounter with a villain changed their whole world upside down. In order to protect those she loves Harmony went beyond her limits to a point she completely lost control. As she stares at the man unconscious underneath her, she is consumed with fear of her own self. The last few words her parents told her before they abandoned her on the streets were starting to become all too real. Does Harmony have what it takes to overcome her fears and become the hero she wanted to be? Will she be able to control her quirk in time? Or will she let the villains win and take their prize?
