SUPER HXEROS

Alien invaders called Kiseichuu are plotting to gradually eradicate humanity by draining them of their H-energy, or libido, and undermining human reproduction. While this issue looms over society, Retto Enjo discovers that his childhood friend, Kirara Hoshino, has closed herself off from the world after a traumatic experience, and is worried about her. He speaks to her for the first time in many years, but their rocky relationship is unchanged. Retto is discouraged by this but encounters a Kiseichuu on the way home from school. He explodes with rage when he witnesses people being drained of their H-energy and losing their vitality, which causes him to…

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.

Kirara joins the team as Hxe Yellow but is unable to unleash her full potential in critical moments and allows the Kiseichuu to escape. The reason that Kirara keeps on failing is because of insufficient H-energy. Momoka Momozono, also known as Hxe Pink, scolds her by saying, “If you want to be a HERO, you have to think of erotic things every day!” But Kirara is unable to cast aside her shyness which makes Momoko even more irritated. Apparently, there is a reason why Momoka is getting so worked up about Kirara’s predicament…

Maihime Shirayuki has a laid-back personality and can’t play sports to save her life. She was chosen to be a member of HXEROS because of her hidden eros and became Hxe White, but she lacks confidence because she thinks she doesn’t have any strengths that set her apart. A Kiseichuu appears at the all-girls high school that Maihime goes to, but how will she fight this enemy and its menacing tentacles? Meanwhile, Sora Tenkuji, aka Hxe Blue, has a hobby that she can’t tell anybody about... Kirara finds out about Sora’s secret, and Sora makes Kirara take part in her antics.

Retto and others head to a nest of Kiseichuus to rescue Kirara who was abducted during a battle. Meanwhile, Kirara sets herself free from an enemy restraint and wanders alone in the nest. She comes across Chacha, a princess of Kiseichuus, who is considered different from the others due to her mutation and has been imprisoned. Chacha wants to stop her other comrades from destroying humanity and plans an escape with Kirara. Retto and others finally arrive at the nest and charge head-on, but...

Chacha joins HXEROS as a new member and starts living with the team in the same dormitory. Chacha enters Retto’s consciousness to find the source of his H-energy. While still merged with Retto’s consciousness, she visits the rooms of Maihime, Momoka, and Sora and stimulates their H-energy. She ends up taking a bath with Kirara, which makes Retto antsy. Chacha’s powers are too much for Kirara, who faints from the heat. Chacha realizes that Retto is in love with Kirara and takes control over his body while whispering to him that now is his chance.
