Toyo

The owner of the udon shop in Asakusa where Tanjirou Kamado stopped by. He served Tanjirou yamakake udon, but Tanjirou, who caught the scent of Muzan, did not eat it, which infuriated the owner. Later, when Tanjirou returned, the owner insisted that he eat the yamakake udon, and was satisfied and sent him off happily after Tanjirou ate it.
