KISSxDEATH(2014)

Alien prisoners exiled to Earth from a distant planet have hijacked the bodies of five girls in an attempt to escape their fates! To capture the prisoners now hiding inside the girls’ mouths, the alien in charge of transporting them named "Z" has taken control of the body of a high school boy, Shingo Tozu. However, Shingo has a terrible case of gynophobia, and this fear of women looks like it’ll make Z’s job a lot hard than it first appeared!
