Kiyoshi

Kiyoshi is a brave young boy who, despite his very understandable fear, managed to survive on his own in a house with three demons all trying to devour him. He is intelligent and crafty enough to use Kyogai's tsuzumi against him in order to survive. Tanjiro Kamado was impressed by Kiyoshi's will that allowed him to hold out for so long under these conditions.

Kiyoshi is a young man in his early teens, with black hair slightly longer than Shoichi's. He has hazel brown eyes just like his siblings and wears a persimmon colored haori over his green kimono.

As an ordinary human, he doesn't possess any additional powers or abilities. However, he is called a |marechi}} by the Tsuzumi Mansion demons since he has a rare blood type that is favored by them.
