Tenchi Musou! Munomaki Kansei Zenya (Tenchi Muyo!)

This one here is an example of japanese hentai manga as it is – a lot of funny faces, wild poses, strange mechanisms and ofcourse nudity and sexual domination! Probably there is some story behind all of this madness yet in order to undesrtand it you have to know the language obviously. Plus this is also a parody on “Tenchi Muyo” series so if you happen to be a fan then check it anyways.
