Tsukiko and Yoto are brought back ten years in the past by the cat god. As they head to the Tsutsukakushi mansion, they meet the younger Ponta, Mai, Azusa, and eventually Yoto, much to Tsukiko's amazement. Shortly thereafter, they meet Tsukiko's mother, Tsukasa, who is brash yet somehow soft towards the younger Yoto, who at the same time badmouths him. Through the younger Yoto, Yoto and Tsukiko are invited in for dinner at Tsukasa's mansion, which is in slight disarray. Here, Yoto and Tsukiko discover that Tsukasa is currently living alone and the younger Yoto constantly visits her to keep Tsukasa company, much to the shock of Yoto and Tsukiko. Meanwhile, Yoto claims that he does not remember anything about interacting with Tsukasa, and later learns that her daughters are currently living in Italy after the death of Tsukasa's husband. The following morning, Yoto stumbles on a young Tsukiko and later Tsukushi, who is deeply hurt by their mother abandoning them. Tsukasa arrives, causing Tsukushi to harshly run off, and Tsukiko then reprimands Tsukasa for being a horrible mother. Back in the mansion, a drunk Tsukasa dresses the younger Yoto in girl's clothes as a drunk Tsukiko lies atop Yoto. Some time later, Tsukiko finds 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.
