As Lala fixes up Nana's De-Dial, Momo tells to Nana grow up while looking at her chest, infuriating Nana. Lala brings out an item that grows Nana's breasts, but it only works for a few seconds and shrinks Momo's breasts. Momo sarcastically admits that she understood Nana's feeling. Later in Mikado-sensei's office, Rito and friends discuss about Lala's inventions and Oshizu asks about Lala's childhood. Momo recalls the frequent incidents with Lala's inventions; whenever she was fighting with Nana, Lala's inventions ran wild and they both cleaned up Lala's mess.
