Super HxEros, Or (Dokyuu Hentai HxEros) is an action-comedy anime and manga series that blends ecchi, romance, and superhero elements into a light-hearted, adventurous narrative. The story takes place in a world where Earth is under attack by alien creatures known as "Kiseichuu," parasitic beings that drain humans of their "H-energy"—a type of energy linked to sexual arousal and desire. The Kiseichuu seek to eliminate humanity's emotional and physical desires, which are key to human reproduction and survival.

To combat this threat, a group of high school students with the ability to harness H-energy are recruited into the HxEros team, a special task force equipped with advanced technology to fight the Kiseichuu. The protagonist, Retto Enjou, is a high school boy who joins the HxEros after a fateful encounter with a Kiseichuu attack. Retto is brave but often embarrassed by the nature of his powers, as harnessing H-energy requires embracing one's physical desires, something that leads to comedic and awkward situations.

Joining Retto is his childhood friend Kirara Hoshino, a cold and distant girl who has lost her emotional connection to others due to a traumatic encounter with a Kiseichuu in the past. Along with other team members, the HxEros squad must learn to work together, balance their feelings, and unleash their full H-energy potential to protect Earth from the alien invasion.

Dokyuu Hentai HxEros focuses on the hilarious and over-the-top battles against the Kiseichuu, while also exploring the relationships between the main characters, especially Retto and Kirara. It is filled with ecchi moments, fanservice, and action-packed scenes, blending humour and outrageous scenarios with an underlying message about human emotions and desires. The series is known for its playful tone, bold content, and its unique twist on the superhero genre.
