My Hero Academia Volume 6 by Kohei Horikoshi
Now that the sports competition is finished, the freshmen class is on to their next assignment: internships. Heroes draft the students based on what they saw at the competition; undrafted students wind up at superhero agencies. Midoriya is chosen by All Might's mentor, Gran Torino. Gran Torino at first seems like a crazy old man, but he has crazy Yoda moves too (you know, that light saber fight with Christopher Lee), so he gives Midoriya a better workout than expected. Meanwhile, the League of Villains tries to recruit the hero killer Stain, with mixed results. On the other hand, the results are completely bad for the civilians in the neighborhood.
The shift into mentoring with an older hero is interesting and gets the students some actual street experience. The ongoing plot against the heroes develops some nice changes and surprises. This book has a huge cliffhanger ending, so I may be reading Volume 7 sooner rather than later.
