The show has it's funny momets and there is a little bit of romance but not much.
The rules of magic was not clear but they made the fight scenes work, some of them are actually enjoyable.
The art itself is good, I like this stlyle but I can see how some would say it's generic.
Some of the elements of the world seemed interesting, like the reincarnation, the demons vs humans stuff and the magic casltes.
There is a Ayanami Rei among the girls, so that's a plus if you are into that.
I recommend this if you like the powerfantasy trope.
