Vandread

Vandread (ヴァンドレッド, Vandoreddo) is an anime series directed by Takeshi Mori and created by Gonzo and Media Factory animation studios.

Plot
Set in a universe where humans have colonized the galaxy, and in one star system, men and women are completely segregated (on completely different planets: Mejere by the women, Taraak by the men) causing the gender war to be more than just a metaphor.
