Teiichi notices Yuko has been acting strange, as she unknowingly keeps lashing out every time he spends time with Momoe. He confides this with Kirie, who tells him she saw the shadow ghost again and concludes the shadow ghost is actually the darker half of Yuko's literal split personality. Soon Kirie, Teiichi, and Yuko encounter the shadow ghost, who reveals to them she is the embodiment of Yuko's hatred and the painful memories she wanted to forget. Denying the truth, Yuko runs away toward the Stone of Curse, and Teiichi eventually catches up to her there. As it is revealed that it is actually a memorial stone dedicated to the townsfolk who died in a plague sixty years ago, it is explained that Yuko was offered as a living sacrifice to stop this plague. The shadow ghost makes a second appearance, unveiling that Yuko was made as a sacrifice against her will. The next day, Yuko continues to hang around with Teiichi, but is much more quiet. The shadow ghost possesses Yuko and pushes Teiichi off a stairway, much to her horror. When a healed and bandaged Teiichi returns to the club room, he encounters Yuko, who does not seem to recognize his face, much to his shock.
