Who's the Flat One Now? Huh? Huh!? Huh!!?

Momiji uses an Ageing Box on Ichiko in an attempt to turn her into an old lady, but it instead turns her into a little kid. As Ichiko escapes from Momiji, she encounters one of Keita's sisters, Mika. As Ichiko spends time with Mika in order to avoid Momiji, she encounters Bob and Momou, who tell her she needs to find another Ageing Box to turn her back to her normal age, and manages to get them to search for it. Ichiko then goes over to Keita's home and requests to sleep over whilst trying to keep her identity a secret. The next day, Momiji follows Ichiko as she goes with Keita's family on a picnic and manages to capture her once she's seperated from the others. As Keita tries to search for her, he falls down a cliffside.
