Kuri no Haha

She is Kuri's biological mother. When she was alive, she got pregnant with Kuri, and her partner who has promised to marry her left her, which caused her to begin to resent Kuri. She ends up killing Kuri and ends up dead herself as Shiro ripped her throat out. However, even during death, she prevents Kuri from being able to go to heaven because of her resentment towards him. She still chases after him but is unable to reach him due to the barrier that surrounds the Youkai Apartment.
