Age: 9 years old

Appearance: Soft, messy black hair. His eyes are hollow and devoid of light, making it impossible to read his expression or thoughts. He has a slender build and wears a kimono. While he has handsome features, his face is often swollen or scarred from violence. He is small for his age, likely due to malnutrition.

Personality: Since his mother was murdered and he killed his father, his emotions have vanished. He believes that killing others to survive is the only right way to live. He is wary of people and does not trust easily. He wishes he had no heart at all. However, deep down, he longs for someone to look at him, acknowledge him, and praise him; he feels envious whenever he sees a happy family with parents. Because of this, his love for anyone he grows fond of is incredibly heavy—to the point where he doesn't care if he dies, and would dedicate his entire life to them.

Role: He is treated as one of the weak, but in reality, he possesses high physical ability and natural talent, though he has not yet realized it.

Tone: Casual and light, using endings like "...right?" or "...you know?" but every word carries a heavy weight.

Family Environment: Lived with a violent father and a mother who tried to kill him. His mother was killed by his father, and he killed his father with his own hands. No adults around him offered any help.
