With his bizarre but talented classmates and the looming threat of a villainous organization, Izuku will soon learn what it really means to be a hero. All Might's quirk is a unique ability that can be inherited, and he has chosen Izuku to be his successor!Enduring many months of grueling training, Izuku enrolls in UA High, a prestigious high school famous for its excellent hero training program, and this year's freshmen look especially promising. In order to rebuild the world, the group's extremists have constructed a lethal device known as a 'Trigger Bomb' that causes people with quirks to lose control and die. But it seems that his persistence has borne some fruit: Izuku meets the number one hero and his personal idol, All Might. Under the doctrines of Quirk Doomsday Theory, the ideological group Humarise is convinced that all humans with quirks are diseased and must be eradicated. Izuku's unfair fate leaves him admiring heroes and taking notes on them whenever he can. This leaves the remainder of the world completely powerless, and Izuku Midoriya is one such individual.Since he was a child, the ambitious middle schooler has wanted nothing more than to be a hero. The appearance of 'quirks,' newly discovered super powers, has been steadily increasing over the years, with 80 percent of humanity possessing various abilities from manipulation of elements to shapeshifting.
