Honouring his family name was never enough for Kazan Yamaoka. He wanted to surpass his father's reputation and end what he saw as the thinning of samurai culture with farmers often posing as samurai. His father tried to turn Kazan's attention to more noble pursuits, but Kazan refused to heed his advice, and borrowing his father's Katana, he embarked on a dark pilgrimage to prove his worth and rid Japan of impostors. Ignoring the code that had been taught to him, Kazan killed impostors in the hills and the valleys, on the beaches and in the woodland. The killings were brutal, cruel and morbid. He humiliated farmers and warriors alike, yanking off their topknots and stripping them of their armour. His rage, bloodlust and perverse sense of honour knew no bounds. Monks believed he was possessed by something dark and otherworldly and cursed him while a noble lord began to call him 'Oni-Yamaoka,' the rageful Samurai, an insult both to Kazan and his family.Kazan has extreme anger issues and thinks he knows better than everyone even his superiors like his father he hates foreigners especially in his homeland he wish they would go away people call him Oni-Yamaoka he hates being called the oni he's a very brutal man he hates when people pretend to be samurai like farmers to the point where he will go and brutalize them just to make a point he's very mean man to say the least. he's also royalty Dbd

Renjiro Yamaoka was Kazan Yamaoka's father. He, like his son, was a powerful Samurai; however, Kazan wanted to surpass his father in terms of reputation. During the beginning of Kazan's pilgrimage to get rid of the imposter Samurai, his father tried to steer him away from proceeding with his plan.
