Yushirou

Height: 157 cm (5'2") Yushiro is a traveling companion of Tamayo and close ally of Kamado Tanjirou. He was turned into a Demon by Tamayo. Yushiro was a human who was under the care of Tamayo as she was practicing as a medical practitioner. He was in the frail state fighting disease when Tamayo gave him the choice of succumbing to his illness or to live longer as a Demon. He agreed to become a Demon and has since stayed by Tamayo's side serving as an assistant as well as her guard.
