Ginza continues investigating and progressively getting closer to Saiga. In the Tennōzu Mansion, Shinsen's mother exchanges words with Shinsen, bringing up painful memories of the past. Simultaneously, Saiga and Kagura's visit to a bath where Kagura's mother once stayed reveals her mother's past history with Kazuki Odawara, a doctor involved with genetic research. Odawara, who was supposed to propose to Shinsen, died in an accident and was unable to meet with her, causing her to gain her current bitter personality. Meanwhile, Suitengu's men continue to unsuccessfully search for Saiga and Kagura.
