This anime depicts what chuunibyou see when they are having their delusions of grandeur: main character is basically a god (he is literally all powerful, all knowing - at least for his followers - and all present), he has 500 elf waifus of all ethnic backgrounds and the whole late 2000's emo vibe to it thinking he is the last cookie of the package.
The show has this recurrent gag of having the main character in the main spot even though he says that he wants to be a background character. Sometimes it even feels like he is auto sabotaging, because how can he be so dumb?
In the end , this show is dumb fun, if you can look over this whole chuunibyou-esque behaviour, you might enjoy it, otherwise you can pass it, there is nothing new about this show.
