Der Katzengott kann grausame Streiche spielen, da er Tsukiko und Yoto in die Vergangenheit zurückschickt. Tsukiko trifft bekannte Gesichter aus ihrer Vergangenheit.
Tsukiko, who along with Yōto, has been brought back ten years in the past by the cat god. As they head to the Tsutsukakushi mansion, along the way they met the younger Ponta, Mai, Azusa, and eventually Yōto, much to Tsukiko's amazement. Shortly thereafter, they meet Tsukiko's mother, Tsukasa, who is brash yet somehow soft towards the younger Yōto, who at the same time badmouths him. Through the younger Yōto, Yōto and Tsukiko were invited for dinner at Tsukasa's mansion, which is at slight disarray. Here, Yōto and Tsukiko discover that Tsukasa's currently living alone and the younger Yōto constantly visiting her to keep Tsukasa company, much to the shock of Yōto and Tsukiko. Meanwhile, Yōto claims that he hasn't remember anything about interacting with Tsukasa, and later, learns that her daughters are currently living at Italy after the death of Tsukasa's husband. The following morning, Yōto stumbles on a young Tsukiko and later Tsukushi, who is deeply hurt of their mother's action of abandoning them. Tsukasa arrives, causing Tsukushi to harshly run off as Tsukiko then reprimands Tsukasa for being a horrible mother. Back in the mansion, a drunk Tsukasa dresses the younger Yōto with girl clothes as a drunk Tsukiko lies atop Yōto. Some time later, Tsukiko founds Tsukasa sewing clothes for her daughters. Tsukasa laments as the results of her inability to take care of her daughters has led her to her dwindling state as she ultimately passes out.
Yôto et Tsukiko semblent avoir été transportés dix ans en arrière par le dieu félin…
