Zhivago

is a Werefox who was a prisoner at the Aberdeen Prison, and the person who raised Ban in his youth and taught him how to steal.

Appearance
Zhivago in his human form, appears to be a young man with short spiky hair that's covered by a bandana. He wears an open shirt with a patterned collar above a dark V-neck shirt, a belt at the waist and dark trousers with a pair of light colored boots.

However, Zhivago is originally a Beastman, specifically a Werefox, having the features of a walking fox with a peculiarly large neck. He wears a simple hooded cloak.

Personality
Zhivago seems to be caring, sharing some food with a young Ban, despite not knowing who he is. This is further proven when he offers Ban to bust out of the prison with him. He also shows great moral and kindness as he was greatly pleasured when Ban told him that he trusts him. However, despite considering Ban a son of his, Zhivago knew his priorities and went to save his own son rather than Ban.

History
Sometime before Ban was imprisoned, Zhivago was as well and had apparently found a way to escape the Prison.

At Aberdeen Prison, Zhivago saw Ban in his same cell, where he offers the boy some food which Ban accepts gluttonously. He then asks Ban if he wants to bust out of the prison with him and comments on Ban's not so childish eyes. He asks the boy his name and when Ban returns the question, he states that his name is Zhivago. Successfully escaping the prison, Zhivago took Ban to his hideout where he offered him more food. He tells Ban that he has a son around his age and asks him his age, but Ban didn't know himself while Zhivago comments on his rude mouth then telling him to never speak of this hideout.

While Ban was kidnapped and being taken to Lord Roxanu to be sold for, Zhivago, being the bandit he is, robbed the cargo he was on. Ban busted out of the barrel and Zhivago was surprised to see him there, taking him away and again helping him with food while mocking him. Ban then asks Zhivago to teach him how to steal, but the latter warns him from its consequences and how his life will never be the same, Ban fell asleep soon after.

The next day, Zhivago was showing off his stealing to Ban. However, when Ban tries to steal he ends up getting caught and Zhivago snatches him back. At the hideout, Zhivago tells Ban about the Fountain of Youth and its guardian saint much to Ban's fancy who suggests they go drink it but Zhivago warns of the guardian again. Ban asks him about his son again and Zhivago responds that his name is Therion, and that he's a shy and sweet boy. He continues to say that he has another kid, a mean brat with a sulky look on his face and a foul mouth, and that his name is Ban. He then explains why he only visits his home at nighttime, and that his son knows of his theft habit. He asks Ban if he trusts humans and Ban replies that he trusts him, which caused Zhivago to force the boy into his embrace, telling him to get some sleep for the next day.

The following day however, Zhivago had overslept and rushed quickly to where he was supposed to meet Ban, but it was too late. He overheard that a Werefox offspring was sighted in the mountains, and saw Ban getting beaten severely. To save his son, or the kid whom in him he trusts? Zhivago discarded his human form and rushed to the mountains, crying for Ban to forgive him. By the time he got there, Therion was already at the verge of death, dying in his arms soon after.

Ten Commandments arc
Zhivago was blamed as the being who revived a dead person, and as soon as Ban heard that, he beat up the humans ganging up on him and took him to the inn. There, Zhivago had already stole Jericho's wallet which Ban retrieves for her. Ban asks him if he's really brought a dead person back to life and the Werefox replies that humans are stupid entities, blaming whatever they don't understand on Beastmen like him. However, as soon as he was leaving, he fell due to illness and was quickly put to bed. He then tells Ban that humans will never know how it feels to live only on stealing.

He then tells them that he didn't expect humans to sympathize with a Beastman, and that he can finally join his sons in the afterlife. Jericho questions again and he tells her that he had two wonderful sons before. He tells Ban that his eyes reminds him of one of them's, proceeding that had that kid been alive he'd be a man at the prime of his life. He tells Jericho that the boy is more than likely dead, and that he was too afraid to show his face in the village again, had he made a different choice he wouldn't have lost everything.

Ban interrupts and tells him that he made the right choice, Zhivago annoyed by his response hears Ban saying that had he abandoned his true son to come save him, he wouldn't have forgiven him which shocks him greatly. Ban continues to say that he never hated nor resented him, and he was his ideal father which puts the Werefox into tears who hugs the Deadly Sin.

Ban
Zhivago was the man who taught Ban how to steal, and made him into a bandit. He held him dearly and considered him his own son.
