When asked how he knew Shion's mother, Rikiga states that Karan had turned him down when he asked her out. Rikiga offers himself to take care of Shion, but Shion himself gets angry on him when he asks Nezumi to work for him as a male prostitute and the two leave. While cleaning Dogkeeper's dogs, Shion is inquired by them about his relationship with Nezumi, and when an angry Nezumi appears before him, they realize he became attached to Shion. Believing Nezumi became soft because of Shion, Dogkeeper attacks Nezumi with their dogs, but their fight is interrupted when Shion arrives.
