Knuckleduster is an individual with a strong sense of justice and drive to do the right thing. He prefers to punch first and ask questions later, as he is willing to beat up people he deems to look suspicious on the slim chance that they may be villains, forcing his teammates to hold him back before he goes too far. Despite this, he has proven to be more intelligent and smart than he seems to be at first.

His costume consists of a simple wrap-around mask tied over the top of his head, a tight-fitting dark shirt, jeans, boots and a long trench coat. On his hands he wears a pair of gloves topped with a pair of brass knuckles, or knuckledusters, from which he derives his name.

In the world of My Hero Academia, 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. 
 
Koichi Haimawari couldn’t make the cut to become an official hero, so he uses his modest Quirk to do good deeds in his spare time. Then one day a fateful encounter with some local thugs leads him to team up with two other unlikely heroes. None of them really know what they’re doing, but they’ve got the courage—or foolishness—to try. But they soon discover fighting evil takes more than just being brave…

Note: Includes 7 extra chapters.

Kouichi Haimawari is a dull college student who aspires to be a hero but has given up on his dream. Although 80% of the world’s population has superhuman powers called Quirks, few are chosen to become heroes and protect people. Everything changes for Kouichi when he and Pop☆Step are saved by the vigilante Knuckleduster and get recruited to become vigilantes themselves!

"Vigilante" has returned to Jump+! Back when Koichi, Pop, and Knuckleduster were still active in Naruhata, they receive a consultation from a girl about a certain problem. Could the existence of the illegal drug "Trigger" be connected to what lies ahead!?
