Yushiro (愈ゆ史し郎ろう, Yushirō?) is a major supporting character of Demon Slayer: Kimetsu no Yaiba. He is the traveling companion of Tamayo and a close ally of Tanjiro Kamado. Yushiro was turned into a demon by Tamayo when he had a terminal illness. He is shown to be overprotective of Tamayo, but still respects her, as he listens to anything she says. But Yushiro is quite rude to others, and is willing to harm them if they try going near Tamayo. But not to the point where he would kill them.
