In Shahal City on the planet Al Shahal, Hayate Immelman discovers a stowaway named Freyja Wion in the shipping docks. Freyja stowed away to run away from an arranged marriage and to audition for the idol group Walküre on the planet Ragna, but Hayate informs her that she is on the wrong planet. When a Vár outbreak suddenly causes Zentradi soldiers to go rogue and attack the city, Walküre and Delta Flight scramble to contain the threat, but are later on met by the Aerial Knights in a fierce dogfight. During the battle, Freyja sings along with Walküre and assists with suppressing the Vár while Hayate commandeers an abandoned Valkyrie and uses it to protect Freyja.
