Not everyone needs a license to fight for justice! In a superpowered society, there is nothing ordinary about evil anymore. Heroes, trained and licensed to protect and defend the public against supervillains, stand above all the rest. Not everyone can be a hero, however, and there are those who would use their powers to serve the people without legal sanction. But do they fight for justice in the shadows, or for reasons known only to themselves? Whatever they fight for, they are called...vigilantes. With Pop possessed and wreaking havoc as Bee Pop, Koichi must push his Quirk to its limits to try to save her. The pressure is on, because if Pop won't fulfill the duplicitous Number 6's plans, the evil villain is more than willing to sacrifice her. The chaos downtown has also drawn the attention of Endeavor, the fiery number two hero, and his scorched-earth methods of dealing with trouble make no distinction between villain and vigilante!
