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!?

2 - Renewed Connections -HEART HYBRID-

6 - World Splitter -GLADIUS-

Himekawa needs more power to fight against the tri-headed dragon that caused her so much trauma in her past.
