I'm not sure, but I know it isn't Rikka because she has a horribly generic and boring design aside from having a skirt so short it would make Shimakaze blush. The whole "thicc" thing, as the thiccfaggots never shut up about, is greatly exaggerated because she barely looks any different from the average anime schoolgirl.
I can't remember all the shows that aired this year because my sense of time is fucked, but Planet With had some cute ones. Very tasty hair.
