My Hero Academia Vol. 20 (manga)

With All Might in retirement, Endeavor takes up the mantle of the number one hero, a position he's coveted for years. But now that he has it, he's not entirely comfortable with the responsibilities and risks that come with it--both heroes and villains are always gunning for number one. What does the future hold for Midoriya, and what do his dreams about One For All mean?
