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!?
If we don't hurry,
 Ataraxia will be wiped out.
Wenn wir uns nicht beeilen,
wird Ataraxia vernichtet werden.
Si no nos apresuramos,
acabarán con Ataraxia.
Si no nos damos prisa,
acabarán con Ataraxia.
Dépêchons-nous 
avant qu’Ataraxia ne soit rasée.
Se non ci sbrighiamo,
 Ataraxia finirà per essere distrutta.
Se não nos apressarmos, 
Ataraxia será aniquilada.
