Jin'you

The character is a jinyou, a human who has his origins from youkai, and thus partially is one.

They are humans, but with inhuman-like abilities and sometimes inhuman-like appearance. They are the descendants of youkai from long time ago who had decided to live on in the human society and thus had took human spouses. The special abilities the jinyou have are a result of their youkai blood that they had inherited from their youkai ancestors (thus the nature of the abilities are also determined by their ancestors).

The kanji for jinyou is 人妖, first one meaning "Man" and the second one meaning "Demon" (this kanji is the same as the one in 妖怪 "youkai", which is referring to the supernatural beings in Japanese and Chinese mythology and doesn't always mean "demon" literally). Putting the two kanji together, it'll roughly mean, "a human youkai".
