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. 
The final showdown in the streets of Naruhata reaches its climax as the monstrous Number 6 goes all out to destroy Koichi. All his life, Koichi dreamed of being a hero. When he realized that wasn't going to happen, he moved on. But now, fighting against the terrifying Number 6, his dream is all he's got to hold on to. If Koichi can tap into the real source of his power, he may at last become the hero he always wanted to be.
