My Hero Academia volume 3 - Kohei Horikoshi

 All Might has arrived on the scene to save the students from an assault of the so-called League of Villains!

But will he be able to stand up to a special genetically engineered foe, made to kill him?

Initially trapped as he focusses first on saving the captives, the students come to his aid in the battle, especially Bakugo and Todoroki.  This results in him getting really fired up, and engaging the Nomu now, knowing what he is up against as the other students hold back the other villains.

Together with the students he bluffs his way to stall, in order for the other pro-heroes of the school to arrive with Ida after he defeats the Nomu.  Now, this whole fight sequence was far shorter then it was in the anime though.

But life at school must go on, and the biggest sports event in Japan is right around the corner.  During the UA Sports Festival, scouts of all the pro-hero agencies are present to watch the students and grade their potential.  During the first challenge, an obstacle course, Todoroki quickly takes the lead by making good use of his quirk.  But when Bakugo catches up, they start quarreling, allowing for Midoriya, using explosives from the course and a metal plate, to sail right by them and take the win!

And as such, the 42 entrants to the second test are known, and the world is seeing the potential of the students of class 1-A...
