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!?

Beh, alla fine il risultato è sempre lo stesso.
Bem, de qualquer forma, eu vim.
