Loveless

Loveless takes place in a world where physical characteristics such as cat ears and tails serve as indicators of a person's sexual experience. In this context, fighting pairs consisting of a Sacrifice and a Fighter are the norm, with the Sacrifice taking damage while the Fighter delivers the attacks. Ritsuka Aoyagi, a 12-year-old boy with amnesia, is drawn into a fight pair with Agatsuma Soubi, whom he meets after his brother's death. As they investigate Ritsuka's brother's past and his involvement with the Seven Moons organization, Ritsuka and Agatsuma develop a complicated bond.
