Earth faces an unprecedented threat from an invasion by the mysterious Kiseichuu. The Kiseichuu feed on human sexual energy, also known as “H-energy”, and weaken the human population. High school student Retto Enjo is a member of the hero group HXEROS, who fight together to save the earth from the Kiseichuu.
...if we hadn't encountered
a Kiseichuu that day...
Wären wir damals nicht
diesem Zensorenkäfer begegnet, …
Si no nos hubiéramos topado
con una Kiseichuu ese día…
Si on était pas tombés
sur cette Pas-rasite,
que se não tivéssemos encontrado
um deles naquele dia,
что, если бы…
мы не встретили цензуросекомое.
