In the world of My Hero Academia, there is no need for a license to fight for justice. In this society full of superpowers, evil is no longer something ordinary. Licensed heroes are trained to protect people from supervillains, and they stand above everyone else. Likewise, not everyone is able to be an official hero. Still, some people choose to help others without holding the legal approval. Are they protecting justice from the shadows, or just following their personal motives? No matter what the reason, they are known as vigilantes.
Koichi Haimawari was unable to pass the screening test of a hero, so he uses his small Quirk to do something good. One day, a sudden meeting with local thugs pushes him to team up with two other unusual heroes. No one knows what they are doing, but they have the courage to move forward. Soon, they learn that bravery is not enough to defeat evil.
