Shigeru is young boy with light complexion and dark, red eyes, just like the rest of his family. His black hair is worn as a buzz cut. Shigeru also wears a light green and black patterned kimono and a light green kimono jacket.
Shigeru appears to be very fond of his brother, Tanjiro Kamado, wanting to follow him wherever he goes and do whatever he does. Like his siblings, he is upset when Tanjiro and his mother tells him he cannot go to town with him.
Shigeru grew up on a mountain alongside his siblings and mother. He is the second youngest son of the Kamado family.
Shigeru and his sister, Hanako Kamado, want to follow Tanjiro into the city to sell charcoal with him. However, their mother stops them and says they would only slow Tanjiro down.
While Tanjiro is in the town, Shigeru and the rest of his family aside from Nezuko are attacked and killed by Muzan.
After Tanjiro gets knocked unconscious by Giyu Tomioka, Shigeru and his deceased siblings and mother are seen looking over Tanjiro with worried expressions.
