Like the rest of his family, Rokuta has light skin and dark red eyes. He wears a bowl-cut and a blue kimono with white diamond patterns.

Personality
While not much of his personality is known, Rokuta seems to have a good relationship with his parents and siblings.

History
Rokuta grew up on a mountain alongside his older siblings and mother. He is the youngest son of the Kamado family.

It appears that Rokuta had a positive relationship with his father as Nezuko mentioned him to be lonely and clingy to Tanjiro after their father's death.

Final Selection Arc
As his father had recently passed away, Rokuta has trouble sleeping out of loneliness. Nezuko is seen carrying Rokuta on her back to lull him to sleep.

While Tanjiro is in the town, Rokuta and the rest of his family aside from Nezuko are attacked and killed by Muzan.

After Tanjiro gets knocked unconscious by Giyu Tomioka, Rokuta and his deceased siblings and mother are seen looking over Tanjiro with worried expressions.
