Ep. 2: Hitagi Senjogahara confronts her traumatic past and regains lost memories with Koyomi's help.

Koyomi waits at Hitagi Senjogahara's home while she showers, recalling Meme Oshino's instruction to meet at midnight. After an argument during dressing, they join Oshino, who advises praying to the crab god rather than attacking it. At an altar, Oshino's questions trigger Hitagi's confession about her mother joining a cult. When Hitagi was sick, her mother brought a cult member home who attempted to assault her; Hitagi injured him while her mother watched, leading to her family's destruction. Hitagi blames herself. She sees a glowing red crab that Koyomi and Oshino cannot perceive. During an attack, Oshino intervenes, allowing Hitagi to beg for her feelings and memories, which are restored. Flashbacks reveal the crab took her emotional weight and memories of her mother. Hitagi regains these, accepts her loss, and values her friendship with Koyomi. The next morning, Koyomi discovers his weight has increased due to the crab god's error.
