Yamanai Ame, Akenai Yoru [English], an hentai doujinshi parodying the Kantai Collection game, by Usubeni Sakurako
I could have done a better job on that Moses photoshop, back in 2014, but it still properly conveys the point, right? ^^
Although, there’s a difference in this volume: the male MC is a douchebag who deserved it. His mistake is to have toyed with a yandere, of all girls.
If I were to sum it up, I’d say that, after several good times with her admiral, Shigure doesn’t take well when she understands she has been used, and thrown away like an old handkerchief. She should have taken a hint when her admiral would always discard her love confessions and make sure to have sex with her when nobody could hear or see them…
And as always with my yandere shares, it’s disturbing that there’s such good art at the same time, huhu.
Thanks to Cgrascal for this one!

Once in a while, it feels good to see a douchebag character come face to face with THIS:

Personally, I believe you should treat all human beings with kindness and respect until they act like assholes. But I’ll add that you should probably be especially gentle with anyone strong enough to carry heavy artillery alone, i.e. strong enough to tear your freakin’ arms off, should they be so inclined. Kind of like crossing the Golden Rule with basic Darwinism.
More than yandere, it looks to me that she just broke under the pressure.
Both perspectives aren’t mutually exclusive, to say it like that.
Cute girl having awful sex.
