Kitani Kouhei

Kitani (Kitani Kōhei, 姫谷浩平) is an ex-yakuza living with the Okinagas and acts as a butler/parental figure to Zenya.

As a child, Kitani had it very rough, living under the care of his abusive parents. He grew to be bitter and careless, nearly getting himself killed in his mid teens in a scuffle with some other boys presumably around his age.

He was taken in by Kunihito and recruited into his gang as an underling and eventually worked his way up in status, becoming his right hand man. Now, with Kunihito excommunicated from the group, Kitani remains loyal and at his old boss's side, despite the circumstances.

Personality
Kitani, despite the grizzled exterior and hard appearance, is a very kind and goodhearted man who only wants what's best for Kunihito and his son, Zenya. He has much patience and only good intentions, even when pressed to more extreme methods.

Kitani is obedient, respectful and knows how to act around his superiors.

Relationships
Kunihito Okinaga- Kitani's former boss, though the man is still referred to as such. Kitani deeply respects and cares for the old man and has been at his side for an estimated twenty years, since before Zenya was even born. Their bond, while strictly boss-and-follower, is strong and long lasting even after all the drama among the Okinaga Family gang. Kitani does consider Kunihito family, despite this.

Zenya Okinaga- Kitani's ward, and Kunihito's son. Kitani has acted both paternal and maternal roles for the boy from a very young age, even more so after Zenya's mother died. Kitani does not view Zenya much as a son or sibling, but family all the same. His high patience level is what gets him through the day at Zenya's side, as the teen is very problematic and stressful with his behavior. While Kitani considers their relationship to be strictly platonic, there are elements to it that seem to point toward something more intimate.
