Half-Beastman

Half-beastkin (半獣人) is a race of children of humans and beastkins. They look like demi-humans, but live longer and appear to have more of animal behavior characteristics, just like beastkins. During the Dark War, Tomonori helped them find a home, for which they were infinitely loyal to him.

The only known half-beastkin in the series is Kokonoe Mercury, daughter of Nine, a human, and Jūbei, a beastkin.

Beastkins, half-beastkins and demi-humans generally appear to possess excellent physical and sensory capabilities compared to humans, as well as extremely long lifespans – but even these advantages cannot save them from being treated by other people as second-class citizens, and even discriminated against and hated.
