Loveless

In the Loveless universe, where the theme of Boy Love meets mystery and the supernatural, it is believed that everyone is born with cat ears and tails. These characteristics will disappear once they have sex.

Ritsuka Aoyagi is a 12-year-old boy who suffers from amnesia. All he remembers is the death of his brother Seimei, who died mysteriously two years ago. On his first day of school, Ritsuka is visited by Agatsuma Soubi, who claims to know his brother.

Agatsuma explains that he and Seimei used to be a fighting couple who could use spells in battle. However, only one of them can use spells, while the other charges up power through lip contact.

Knowing that Seimei's death is linked to the Seven Moons organization, Ritsuka asks for Agatsuma's help to uncover the truth.
