Owner of the Souma Hot Springs and mother to Ritsu Souma, the monkey spirit. Like her child, she has visibly bad constitution and apologizes profusely for almost any minor mishap.

Unlike many parents of cursed Soumas, Ookami is found of her child and asks Tooru to think fondly of him. She is also fond of the other cursed Soumas who com to visit the hot springs.

In the 2001 anime, Ookami plays a larger role, narrating Yuki and Tooru's visit to Ayame's dress shop, constantly making errors and subsequently apologizing for them.
