Teiichi notices Yuuko 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 Yuuko's literal split personality. Soon Kirie, Teiichi, and Yuuko encounter the shadow ghost, who reveals to them she is the embodiment of Yuuko's hatred and the painful memories she wanted to forget. Denying the truth, Yuuko 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 Yuuko was offered as a living sacrifice to stop this plague. The shadow ghost makes a second appearance, unveiling that Yuuko was made as a sacrifice against her will. The next day, Yuuko continues to hang around with Teiichi, but is much more quiet. The shadow ghost possesses Yuuko and pushes Teiichi off a stairway, much to her horror. When a healed and bandaged Teiichi returns to the club room, he encounters Yuuko, who does not seem to recognize his face, much to his shock.
