The premise is absurd on purpose: parasites that feed on sexual energy, fought by teenagers who have to get horny to power up their abilities. The show commits completely to this ridiculous logic and never winks at the camera about it. You're watching a genuine action series that treats "H-energy" as seriously as any other power system, which means the comedy lands because it's never about the show being self-aware. The ecchi exists to actually matter to the plot, not as window dressing. It's built for people who want their anime stupid in exactly the way it intends to be stupid, where the group dynamic matters more than any single joke landing.
Parasitic aliens called Kiseichuu have begun siphoning humanity's sexual energy, leaving entire populations drained and defenseless. High school student Retto Enjou discovers he's one of the few people capable of fighting back when he joins HXEROS, a secret organization of young warriors who combine their desires and willpower into devastating attacks against the invaders. Operating in the shadows of everyday school life, Retto and his team must balance their mission to protect Earth with the awkwardness of channeling intimate emotions into combat. The battles are intense and absurd in equal measure, mixing supernatural action with the fumbling uncertainty of adolescence. Every confrontation demands that the heroes tap into their most genuine feelings, making victory as emotionally raw as it is visually explosive. The show walks a deliberate line between comedy and genuine stakes. Saving the world requires vulnerability, and these teenage fighters learn that strength isn't about hiding who they are. It's about facing threats head-on while growing into themselves, one weird battle at a time.
