As fanservice harem battle manga go I actually kinda like this one. I appreciate that the MC isn't overpowered and has to work together with the FMC to defeat enemies (indeed, she's actually stronger than him, with the MC serving as support). I read a few more chapters in the raw and remember also being impressed by how the class VP's arc went, though I can't remember now exactly what happened.
The biggest flaw is that none of the characters really have much personality. While the MC starts out the series planning to commit murder and sometimes has edgy "I can't trust anyone, I hold grudges" monologues, he still basically acts like your standard heroic shonen MC, and the FMC is basically just a generic nice girl. Still, it's at least good enough to hold my interest. Thanks for the translation!
