any1 know where the image is from
and someone know other grotesque castration hentai/yaoi?

Giglio . You dont get to see it done but you see the result. Tbh given what the guy did I felt it was sort of humorous and deserved.

I remember there was a near-miss in Aki-Sora . . . Yandere sure are scary . . .

I think the image comes from a hentai game but I can't recall the name.

I believe you meant "castration".
