Man... this series started like a trope-filled harem with lolis and very quickly devolved into edgy overpowered bullshit fights. Why kill the father? Why have all of the heroes turn into demons just because? So strange, and it's not like this was an axe, this has been a long time coming.
Also, I do have to say it's pretty funny that almost every single spell that is used strips the female characters completely naked no matter what. Anytime a guy gets hit, clothes stay on, except for the old guy, all that remained was his cloak...
