I know manga loves to infantilize women, but... she's 16, Japanese, and just realized Santa isn't real? And the oh-so-convincing impression she has of Santa is her mom (who apparently also looks like she's a teenager) in a slutty dress with a plastic mask?
Yeah, yeah, I know this horse ceased to be a long time ago, this is not the work to go to for nuance but... at this point I'm really only here because I like the way the artist draws nipples and there aren't many full-nudity ecchi series. ><;
