Two major things happen in this one and both center over their training sessions. The first pits MIdoriya against Bakugo, the former as a hero and the latter as a villain along with Uraraka and Ida. Bakugo goes completely out of control. I'm very surprised none of the teachers really do anything about this. He seems almost truly a villain.

The second, and more important thing is the training session at the rescue scenarios (flood, fire etc) when a huge cadre of villains attack the kids who have barely begun training and only have two professors there. Worse, the professor the villains want to kill, All Might, isn't there and the kids have to fight or die.

It is a fun manga but there are so many characters and several I don't like, such as Bakugo (who I suspect I'm not meant to like) and Mineta who is a bit of a pervert (thankfully he's toned down in the anime which otherwise follows pretty closely). I like it but I'm also glad I can get it from the library.
