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.
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.
