In My Hero Academia, there is no legal and official way to fight for justice. This world is full of superpowers, and evil is no longer ordinary or simple. Professional heroes have a license and are trained to protect common people from strong villains, and this places them above others in society. Likewise, many people can’t become official heroes, still some use their abilities to help others without holding a license. Are they real defenders of justice, or do it for their personal reasons? Still, they are known as vigilantes.
Koichi Haimawari can’t pass the test of being a licensed hero, so he uses his quirk to help people by doing small good things. One day, a sudden encounter with nearby thugs makes him pair up with two unlikely fighters. None of them knows how to become a hero, but they are courageous and reckless enough to move forward. Soon, they learn that bravery is not enough to fight evil.
