When he was still alive, he was picked up by Kohina. He knows everything about Kohina from the things she likes and dislikes, to her weight and height etc. He dislikes Kokkuri-san and thinks he is trying to interfere with Inugami's and Kohina's relationship.
Since he never knew his gender when he became a spirit he can switch between being a Male or Female, his mindset can be of either gender, in others words, while in female form he can have the mind of a woman.
He is masochist, the thought of Kohina hating or punishing him gets him excited. He dislikes everyone including himself, except Kohina.He criticizes everything Kokkuri-san does. He does like having quiet time to himself, when he does he make coffee. Loyal. [Source: wikia]
