Living in a superhuman society, it is hard to feel special. Even more so when
the spotlight only shines on professional heroes, those legally authorized to
use their special powers known as Quirks in public for the greater good.
Kouichi Haimawari grew up aspiring to be a hero, but with a mediocre Quirk
like "sliding" that ties him to the ground, he soon came to the conclusion that
he could only ever admire them from below. Despite this, Kouichi finds
contentment in using his Quirk to carry out day-to-day good deeds, such as
returning lost items and helping the elderly cross the street. However,
Kouichi's tame life takes a swing into the turbulent when he is rescued from a
back alley brawl by Vigilante, or illegal hero, Knuckleduster. Seeing hero
potential in Kouichi, Knuckleduster enlists his help in tracking down the source
of a dangerous drug known as Trigger that boosts the user's Quirk at the
expense of their rationality. Set in a time before the events of the original
story, Vigilante: Boku no Hero Academia Illegals follows Kouichi as he
chooses to don the reputation of a villain and become a Vigilante, operating in
the shadow of the law to prevent crimes from taking to the surface.
