It's hard to say much about Watashi ni Tenshi ga Maiorita!
It's a story about an otaku female lolicon that ends up surrounded by little girls. It would be a pretty cute and wholesome anime, if it weren't for the fact that there are clear moments when the protagonist has one hell of a female boner for the little girls, and it gets a bit uncomfortable.

I give it a 6/10, since there's not much that happens noteworthy. If you're a bit of a lolicon yourself, and what to see them in cosplay outfits, you should give it a watch.
