In a future world where invaders from another dimension have driven humanity to live on floating islands in the sea, Hida Kizuna becomes a member of the elite Amaterasu squadron.  In order to power up the mech suits of this all-girls combat team, he has to... do lewd things to them!?
It's decided by how they live.
Sondern dadurch, wie sie leben.
Se decide por cómo vive.
Lo decide el cómo vive.
mais ce qu’il décide 
de faire de sa vie.
ma dal modo in cui vive.
É decidido pela forma que elas vivem.
