Dokyuu Hentai HxEros

A group of mantis-like aliens called Kiseichuu invade Earth with the intent to destroy humanity by draining their H-energy, a form of sexual energy essential for human reproduction. In response, the government forms a team of superheroes who use technology to convert erotic energy into powers. Retto Enjou, a high school student, joins the team and works alongside four female members, including Kirara Hoshino, his childhood friend. Over time, Kirara became distant and cold after a past encounter with the Kiseichuu. The story explores Retto's efforts to combat the alien threat, maintain team cohesion, and possibly reconnect with Kirara.
