This character is the long-term partner of Asakura, whose relationship took a dark turn when she was exchanged for a single night with Okubo to resolve a demonic issue. Instead of the agreed-upon arrangement, Okubo and his associates used her for blackmail, taking compromising photos. Fearing for Asakura's safety, she stayed with Okubo, but upon learning the truth about the exchange, she attempted suicide until she was miraculously saved by Eikichi.
