La spirale de la bouche d'égout

Whilst out shopping for some more cream, Kyōko and Yachiyo end up meeting Otoo's long lost wife, Haruna. As Yachiyo debates whether to tell Kyōko about her, she disappears again. As Yachiyo feels guilty about it, Mahiru learns about Jun's one-sided crush on Yachiyo and starts feeling sorry for him, leading Sōta to believe she has a crush on Jun. With some support from Jun, Yachiyo apologises to Otoo after he returns and cheers up.
