Shiemi's Mother is the owner and shopkeeper at the Exorcist Shop, which is located somewhere on the campus of the True Cross Academy.
Shiemi's Mother has dark blue eyes and chocolate brown hair that she wears in a loose bun near the nape of her neck; she has a small red and gold hair pin adorning the right side of her head, and a large turquoise hair pin on the left side. Similarly to her mother, she has pieces of her hair falling in front of her face and a large section of it, on the left side, is curled. She is a heavy-set woman who appears to be slightly taller than her daughter. Her usual attire consists of a purple, floral-print kimono with a black sash around the waist, as well as a pale red shawl and traditional Japanese footwear.
Shiemi's Mother is always worried about her daughter, but she doesn't know how to show it very well, as it usually comes out as demanding rather than caring.Because of this, and her constant fighting with Shiemi, she is quite down on herself, considering herself to be a failure as a mother and thinking that it is her fault for not spending enough time with Shiemi when she was a child.
True Cross Academy arc
Shiemi's Mother is smoking from her pipe as Yukio enters her shop and she greets him by saying good day. After purchasing some of her products Yukio asks her how Shiemi is doing. She replies that they are currently fighting, so Shiemi won't speak to her, and that Shiemi's legs get worse by the day. Later on Shiemi's Mother goes with Yukio into her mother's garden and demands that Shiemi let Yukio examine her legs, so that they can figure out what's wrong with them. Shiemi's Mother is shocked to hear that Shiemi's leg problems are the work of a demon and becomes concerned that Shiemi is possessed, but Yukio assures her that she isn't. When Yukio states that the demon is somewhere in the garden she orders Shiemi to leave the accursed garden at once; this causes Shiemi to tell her mother that she hates her before fainting on the ground. After putting Shiemi in her bed she begins to talk about how Shiemi's legs started to deteriorate after her grandmother passed away, she then sadly walks away claiming that she is a failure as a mother. After Yukio and Rin defeat the demon in the garden Shiemi shyly walks over to her mother to apologize, but before she can Shiemi's Mother hugs her tightly and cries while saying how worried she was.
