Overview
Happy Around! requires a surefire hit to even compete with Photon Maiden. Unfortunately for Rei, her friends insist her new song will give them just the edge they need.

Summary
Rinku walks in on Rei singing her song and encourages her to perform it at the Battle Mix Party. While Rei is initially hesitant as she fears the song does not match the unit's image, she agrees upon receiving the others' blessings.
