So there's basically nothing to this manga, and I don't think I've ever seen anything like it. There's no plot, there's no emotions, there's no story, there's no setting. Literally every single chapter consists of a few girls (predominantly the titular onee-san) who get worked up over games and flash the reader boobs. There's no emotional component to that either, no shame, or embarrassment, or even a sense of showing off. It's literally like they're alone and stripping to take a shower or something, but there's other people in the room.
So yeah, the entire series might as well just be an artist collection or something. Don't get me wrong, the art is hot, but there's no romance or anything even remotely approaching it. To be honest, none of the characters have any emotions at all. Just 'off mode - normal human', and then 'playing games - flash everyone mode'.
