Yes. The main characters are all school students. The first two don't have the same time related element and the later ones though, so it's more a part of their character than a game aspect.

Just try to remember to not get cocky when playing, it's very difficult to actually be overpowered because of the way the battle system is made. And this is a good thing until you forget, get cocky, and some enemy group wipes the floor with you XD
