Ep. 4: Yoto mencari bantuan Azusa untuk mengatasi jarak emosional Tsukiko dan proposal pernikahan aneh Tsukushi.

4

Tsukiko explains that she feels her clingy behavior drove Tsukushi away from her, which led to her making the wish on the stony cat. As Yōto tries to ask Tsukushi about this, she tells him she was the one who made the stony cat as a way of apology to Tsukiko following an argument. The next day, Tsukiko asks Yōto to help her shop for costumes for her performances with the children. Later that night, Yōto encounters Tsukushi, who states that she wants to get rid of her sisterly bonds with Tsukiko and does not believe her lack of expressions to be related to the stony cat. Afterwards, Tsukiko expresses her concerns that if she were to get her expressions back, there would be nothing connecting her to Yōto. Earnestly wanting to help Tsukiko, Yōto gets Azusa's help and calls out Tsukushi to the stony cat. There, he asks the stony cat to take away his urge to run away in exchange for his underwear. He announces that he loves Tsukiko as his little sister, leading to Tsukushi to reveal that she does love Tsukiko, albeit in a romantic way and that she wants to cut off their sisterly bonds so that they can get married in Massachusetts, a dream that is quickly shot down by Tsukiko. Tsukushi then calls out to the stony cat, who returns the meat bun containing Tsukiko's expressions, but Tsukiko decides to give it to Tsukushi instead. Some time afterwards, as the stony cat's power has apparently disappeared and Tsukiko has been rather cold towards him, Yōto is shocked to discover his house has suddenly disappeared.
