17 Jul >Five years back, alien beings referred to as “Kiseichuu” invaded the planet.

with all the types jeopardized, the Kiseichuu are determined to dominate Earth via a plan that is deadly would slowly get rid of the human race: remove mankind's sexual drive making use of different techniques, permitting them to perish away. The HxEros device was developed—a powerful weapon that only those with high levels of erotic energy can utilize at its maximum capacity in response to the Kiseichuus' scheme.

Retto Enjou, a higher schooler harboring a tremendous hatred toward the Kiseichuu, joins a small grouping of HxEros users to fight against them and protect humankind.
