He is a college student who becomes a half-ghoul after an encounter with a ghoul.
Kaneki is short, scrawny, and prefers to read books. He has black hair.
Kaneki's hair changes color from black to white after he is tortured. The change in color is due to an increase in cellular tubes in his RC cells, which increases his RC cell count. The change in color also has a metaphorical meaning, representing the loss of his purity.
