Tsukiko believes her clinginess drove Tsukushi away, prompting a wish on a stony cat. Tsukushi reveals she created the cat to apologize after an argument. Tsukiko asks Yoto for costume shopping help, while later confessing she wants to sever sisterly ties with Tsukiko, dismissing the cat's influence. Fearing losing her connection to Yoto if she regains emotions, Tsukiko worries deeply. Yoto enlists Azusa to confront Tsukushi at the stony cat. Yoto trades his underwear to remove his urge to flee, declaring his love for Tsukiko as a sister. Tsukushi admits romantic feelings and a plan to marry in Massachusetts, which Tsukiko rejects. The cat returns Tsukiko's expressions in a meat bun, but she gives it to Tsukushi. Later, with the cat's power gone and Tsukiko cold, Yoto finds his house has vanished.
