Aira in Wonder Girl

A mysterious girl appears saying that the city smells interesting. Aira seems to be too caught up with the prism show even when it is Uru and Eru's birthday. They manage to convince Aira, Rizumu, and Mion to go to Prism Land, an amusement park that Aira described that Uru and Eru wanted to go to. The twins end up running to the tallest tree in the park because Aira yelled at them not knowing their feelings. The Harune twins meet a girl named Kaname Chris who is also climbing the tree. Aira finds the twins but they don't forgive her. It turns out that they were lonely without their big sister and they don't actually hate the prism show. Aira and Kaname save the twins who were about to fall off the tall tree. Aira, Rizumu and Mion all do a prism show. At the end the twins decided that they want to be Pretty Top's manager.
