Boy meets adorable tsundere loli with amazing zettai ryouiki.
Picked this up thanks to the loli anime thread. I liked the mixture of mundane romance conflicts with the main plot, even if it was a little contrived that Yuji, Yoshida, Shana, and Margery's two henchmen are all in the same classroom. Many opportunities for girls to get flustered and jealous, which is always fun to watch. The villains, on the other hand, were boring, a series of edgy faggots each of who overstayed their welcome. They don't seem to have motivations beyond "I sacrifice mundane humans so that my special self can be immortal", except for that doll guy at the beginning, whose difference is that he wanted immortality for the doll girl he loved instead of for himself.
I haven't yet committed to watching the seasons after the first but I quite enjoyed the first season especially the ending with its cheesy montage. I think I'll give the light novels a read.
