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!?
But is it really okay
for me to come to Ataraxia?
Aber ist es wirklich in Ordnung,
dass ich nach Ataraxia komme?
Pero ¿está bien que venga a Ataraxia?
Pero ¿de verdad puedo venir a Ataraxia?
Tu es vraiment sûre de toi ?
Ma sei proprio sicura
 di volermi qui ad Ataraxia?
Não tem problema algum eu ficar em Ataraxia?
