Present Wa Santa-san De Onegaishimasu!
Zetsubou ni Nake
I'm not too entirely sure how to feel about the rape-revenge stuff, as raping someone whilst drunk isn't entirely excusable, we can't find any semblance of proof why Akamine did such a thing, character wise and context wise, Saeki is the only excuse I can think why he'd possibly do it.. Maybe I shouldn't be too hung up on it, but it is weirdly intriguing! We don't get reason for the rape and at some point I didn't even believe he did it because of how indifferent his character was about it. Who knows if it was a psychological reaction Utsumi had, (and I'd rather not assume because we were given explicit context that yes, he was raped) Either way, a pretty good manga! Was interested in the dynamics, the art was great (though still uncensored terrifies me) and the psychology was hitting. Top tier, but not that top tier since it still confused me. Should've answered
