Ep. 11: Tsukiko and Yōto travel ten years back to meet younger Ponta, Mai, Azusa, and Yōto at the Tsutsukakushi mansion.

Tsukiko and Yōto are transported ten years into the past by a cat god, arriving at the Tsutsukakushi mansion where they encounter younger versions of Ponta, Mai, Azusa, and Yōto. They meet Tsukiko’s mother, Tsukasa, who is brash yet soft toward the younger Yōto, who simultaneously badmouths the older version. Invited for dinner, the pair discovers Tsukasa lives alone while the younger Yōto frequently visits to keep her company. Yōto recalls no such interactions and learns Tsukasa’s daughters reside in Italy following her husband’s death. The next morning, Yōto meets a young Tsukiko and Tsukushi, who is hurt by their mother’s abandonment. After Tsukushi runs off, Tsukiko reprimands Tsukasa for her poor mothering. Later, a drunk Tsukasa dresses the younger Yōto in girl’s clothes while a drunk Tsukiko lies atop him. Tsukasa is later found sewing for her daughters, lamenting her failures before passing out.
