Noguchi

Not much is known about his personality, but he is impressed by the Hashira's skills, although intimidated by their strength and believes that their intensity scares off any Tsuguko. Noguchi is also shown to take his duties seriously, as he and Shimamoto help kill a giant demon in the Infinity Castle in order to protect the Hashira and conserve their energy to take on Muzan.

Noguchi is a male with a long bob cut hairstyle, green eyes, and an x-shaped scar on his right shoulder.

Noguchi is presumed to have above average Demon Slayer abilities, as evidenced by him reaching the final stage of Hashira Training, and not quitting the grueling training like other Demon Slayers. In addition, he takes on and kills a giant demon with the strength of a Lower Rank with the help of Shimamoto.
