Being called out by his sister, Hida Kizuna visited the Strategic Defense School Ataraxia. He met with the girl manipulating the magic conducting armour (Zeros), Chidorifuchi Aine. All of sudden, in front of his eyes, Aine was removing her clothes. “Don’t look, you pe*vert!” “No, it was your fault right!?” To the unfortunately sharp tongued Aine, Kizuna couldn’t help but be confused. However, there, a critical mission’s communication arrived. And its contents――to massage Aine’s breasts!? In fact, ecchi acts from Kizuna have the power to power up the girls. With that power the future of the fight with another world was at stake!!
