It is a hentai which contains mostly futanari, yuri, incest, virgin, blood and forced sex (I wouldn't call it rape since the valkyries start enjoying it midway). The story had some potential, but expecting a good plot from a two episode hentai is maybe, just too much. As such, the story becomes confusing and boring.If you don't care about the story, I'll sum up the hentai - It's about a valkyrie who goes on a rampage and fucks her sisters xD. Nearly all the characters are valkyries (atleast the victims are), so all the sex scenes are pretty much enjoyable. If the back stories were explained better, Iwould have given it a higher rating. Still, it's a good watch if you like futanari!
