I’ll be honest, I don’t remember Yuasa Shoko from the Hyouka anime and I’ve watched it several times (I really like the art style). But it’s still an awesome book.
Basically, “Vagina Research Club” is a synonym for “Rape Club”. Yuasa and Irisu do all sorts of fucked up things in the name of “research”, and just when she thinks she’s about to graduate and get out they get her knocked up. Nice.
Half of the book is pretty pictures of the girls in lingeries (editing note: you might have to redraw these). The other half is RAPE TIME, because photographers can’t be expected to watch teenagers in underpants and not get a rape boner.
Also, apparently being raped five times definitely gets you pregnant. I think I’m going to start up my own fertility clinic.
If you like girls getting their eyes cut out and skull fucked, then this is the book for you. Hard guro warning.
The friends have a secret clubhouse but they get shut out, so they go use the abandoned factory instead. And nobody ever saw them again. Because they had (at minimum) an eye removed and got raped until they didn’t know which way was up.
