Kamui Yato

As a child, Kamui was a loving and caring son and older brother for his family. He cared for his sick mother to the point of hiding his injuries from her so she wouldn't worry and always took care of Kagura as their parents couldn't. He used to be close with his father, often longed for his presence as Umibouzu seldom at home and aimed to become strong like him. At that time, child Kamui used to beat up anybody who insulted his family and attacked him, justifying his action as protection for his family until Umibouzu scolded him that as he is a Yato, what he did was no different than bullying the weak. Kamui took his father's scolding and since then refrained from fighting back, but the continuous beating he had to endure that led to Kagura got attacked and his mother's worsening health took a toll on the child Kamui, who began to question the point of holding back his power when it just cause harm to his family. Finding out about the true cause of his mother's illness was the final straw for Kamui, who began to blame himself and his entire family for causing his mother's suffering. When Kamui failed to kidnap his mother in attempt to save her, Kamui lost hope and buried his grief by focusing on his goal to become the strongest and surpass his father.

As Kamui grew up, like a Yato clan member in general, Kamui is a battle-loving individual, always looking forward to fighting strong people. He has a belief that the Yato members need to always stay on the battlefield, and this is why he disagrees with Housen staying in Yoshiwara as its ruler. He has no interest to romance viewing fights with more importance. The continuous battles he experienced developed a sadistic streak for Kamui, which he always shows in battle while smiling. Despite majoring excellently in the fighting field, Housen describes him as ignorant for being too young and not wise enough to understand the reason for his father and Housen's to settle down and appearing less on battlefields. Kamui has stated that he doesn't like to kill women, as they could give birth to strong children with high potential (to presumably fight him).

Losing his mother also caused Kamui to believe that having emotional ties to one's family is a weakness. He chided Gintoki that if one doesn't have the power to protect their loved ones, then they shouldn't have people they care for from the very beginning. In reality, this stems from the fact that Kamui hated himself for unable to save his mother and detach himself from his family or having someone to care for out of fear experiencing the same loss again. After fighting against Kagura and the others at Rakuyou, Kamui was finally able to reconcile with his past and his bond with his family.

Appearance: Like his sister, Kagura, Kamui has blue eyes and vermillion hair, albeit his hair reaches his lower back and is always tied in a braid. He also has a single lock of hair sticking out from the top of his head which he inherited from his mother. Kamui wears a traditional uniform used in Chinese martial arts, with a black and white top sporting elbow length sleeves, and gray pants that reaches the middle of his lower leg. Like all Yatos, he has smooth fair skin, and his body is well developed with strong, flexible toned muscles. He is almost always seen with a cheerful smile on his face.

It has been shown that women find Kamui very attractive (check out the sexy son hypothesis) considering how much attention he got when he walked on the streets of Yoshiwara alone.
