Yōto is on his way to school, still bothered by Emi's wishes and Tsukiko's cold behavior towards him, and along the way he meets Ponta, who informs him that his rabbit has gone missing. Yōto realizes that Emi's wish of being Ponta's sister has been cancelled. He makes up with Azusa at school and asks her to help him find Ponta's lost rabbit. Emi and Tsukiko have a swimming contest in which the result is a draw, and after the contest Emi cancels her wish for all the girls in the school to wear swimsuits. Ponta later reclaims his lost rabbit thanks to Azusa's efforts and remembers Emi's and Yōto's close relationship, much to Yōto's bewilderment.
