Hisa is an elderly lady who welcomes Demon Slayers to rest in her house. Tanjiro Kamado and his group visit her after they fight Kyogai at the Tsuzumi Mansion. Hisa is a short, old woman with wrinkled skin and thick eyebrows. Her bulky, gray hair is tied into a medium sized bun with two strands poking out behind her ears. In most of her appearances, Hisa is seen wearing a plain maroon kimono with a purple obi with black zōri and white tabi socks. Hisa comes off as a very kind and welcoming person, bringing in the injured Demon Slayers without hesitation and providing them with commodities for recovery. Despite Inosuke Hashibira's and Zenitsu Agatsuma impolite nature, she proved to be very patient with them and doesn't appear to be affected by their remarks. Inosuke noted that even with his enhanced perception, Hisa's kind demeanor made it impossible for him to detect her presence, because she bore no ounce of ill-will.
