Hayate meets Freyja, a stowaway. Soon after, they witness the Walküre putting down a riot.

Freyja visits the planet Ragna with Hayate for the final audition for Walküre.

Mirage has been appointed as Hayate's training instructor. Hayate does not listen to Mirage at all.

Freyja's debut as a Walküre happens at a vaccine concert on the planet Randall; Freyja is fidgety and restless before her first concert; Mikumo asks Freyja, about her feelings; Freyja makes up her mind to sing as a Walküre.

The Aerial Knights, who wield the Var with the legendary Singer of the Wind, swiftly bring down two stars; despite suspicions that Freyja is a spy, she maintains a determined and cheerful facade in front of the team.

Xaos and the New U.N. Spacy lose ground to a group of manipulated soldiers that have been infected by Vár; Messer scolds Hayate, who targets only the wings of enemy aircraft instead of the pilot and warns him against naive tactics.
