Some info:

  He has a strong sense of duty and can't stand acts of injustice, and will act in consecuency.

  He turned into a inugami by his last owners will, but killed they after he realized that they performed the rite on his childs when he was away on a mission.

  In the last time gained the taste to cultivate. The kind of agriculture works helps him to calm his mind, and obtain a profit.

  He's bad at words, but try his best to demonstrate his feelings at least with actions. But it's not that he doesn't talk at all. It's just that sentimental things are hard to put in to words.

  Totally bottom.

Afilliations

Aliosha	Sonjya	Vladya	Oni
Actual partner. Although they're very different in personalities, they complement each other. He strived a lot to demonstrate Aliosha that's he's not alone, and that some things needs to be done with the help of others. Even when Sacha is not very expressive and is difficult for him to show his emotions. He love's him very much, and that's why.	His adoptive elder daughter. Their relationship is somewhat close. He likes to pamper her in some things she demands, but is also strict in some others and doesn't aprove at all her interest in Oni. Both of them have a strong personality, so this causes loud arguments when they don't think the same.	His adoptive younger son. Their relationship is somewhat close. Vladya is affectionate towards him (and in general, with close people) and very talkative. But it wasnt always like this. Vladya was very afraid of him when he was a little child, and to gain his trust, Sacha had to learn to be patient and attentive, 2 things that he never dreamed to be at that time.	He can't stand the sight of him. Anyway, is a one sided hatred. Sacha can't forgive him for having a neutral position in almost everything, (to be continued later)
