Madoka Kyono lives a busy life as the proud, and only, member of the Kamogawa Girls' High School Jersey Club, a school club dedicated to helping those in need. When a mysterious girl named Lan shows interest in joining the Jersey Club, Madoka is at first thrilled at the thought of having a new club member.
Madoka's excitement over her triumphant victory is short-lived when she is told by Pharos officials to be ready for the next battle. Feeling like she's been tricked into becoming a Vox pilot, a furious Madoka plans an escape.
Madoka, Lan, and Muginami spend a peaceful day at the Kamo Girls' High Oraga Festival, enjoying all the events they helped put together. Meanwhile, Villagiulio is readying his forces to launch a full-scale attack on Earth to destroy the Vox and Pharos.
