Hybrid x Heart Magias Academy Ataraxia

Twice in the span of 15 years, a mysterious alien race attacked Earth via extra-dimensional portals called Entrances using mecha-like entities called Magitech Weapons, destroying the planet's conventional military forces in the process. The second time around, humanity was forced to migrate to Megafloats in the ocean, as Entrances can only be opened above land masses of sufficient size. Only one weapon seems capable of successfully combating the threat, the HHGs, or Hybrid Heart Gears, which have been installed in select teenagers who show high compatibility. Kizuna Hida, as the son of the HHG's inventor, was among the earliest to be installed with such gear. Still, even though his gear Eros is weak in combat compared to the trio of girls who form the strike team Amaterasu, he is given captaincy of the team for one important reason, by bonding with the girls through lustful behavior, he can recharge their Hybrid Counts which allows them to use their Gear and even power up the girls.
