Roaring Muscles (うなれ (きん) (にく) Unare Kin'niku?) is the second chapter of Kohei Horikoshi's My Hero Academia.


The chapter begins where the previous chapter ended off, with Izuku crying in joy for having his dream acknowledged. All Might tells Izuku that he is worthy to inherit his strength, confusing Izuku. All Might says that his Quirk can be passed down and has selected Izuku as his successor. All Might tells him that the name of his power is "One For All". Izuku asks why All Might would give his Quirk to him, to which All Might replies that he doesn't mind giving it to him and because he shined more than any of the other so-called "heroes". All Might says that the decision is his to make and Izuku decides to accept All Might's proposal.

Izuku trains to inherit One For All.

All Might begins to train Izuku in order for his body to inherit One For All, saying that if he gave it to him now, his body would be blown to bits. All Might has Izuku clean the Takoba Municipal Beach Park of its trash as a great way to strengthen Izuku's body for the next ten months, as U.A. High School's Entrance Exam begins by then, wanting Izuku to become a vessel by then.

However, Izuku doesn't follow All Might's directions and overworks himself to the point of collapse. All Might scolds him but is moved by Izuku's motivation to become the strongest hero and modifies his plan to match Izuku's state.

After ten months of intense training, it is now the day of U.A.'s Entrance Exam. Izuku's body is now more refined and muscular, which causes All Might to say that he is now a genuine vessel. All Might decides to give Izuku his reward for having worked so hard for the last ten months, saying he has earned it fair and square: the One For All Quirk. All Might gives Izuku a piece of his hair to eat, much to Izuku's confusion. All Might says that it doesn't matter how he takes his DNA, but due to the Entrance Exam beginning in a few hours, he needs to inherit it immediately, because the DNA takes time to process.
