Gee, it's getting dramatic. Evaluated as a stand-alone chapter, it's a pretty good one: more plot, more action, a devious trick by the villain, and the hero acts up once again.
In the overall scale of things though, this is pretty ridiculously trite: crazy weird school, teenagers with godlike powers and grand ambitions (what happens with the adult monsters?), harem girls getting beat up and spouting dramatic lines about friendship and cooperation...
