Story Role

Freya enters alongside Sleipnir shortly before its tournament battle with Kogarasumaru. Her unusual appearance catches Kazuma Mikura's attention before the match, while her equipment helps establish that Sleipnir's riders use highly specialized forms of A-T technology.

During the aerial match, Freya's aircraft is the first to exhaust its fuel. Rather than falling with it, she deploys her sword into its parasol form and uses it to remain mobile in the air. This turns the destruction of the planes from a straightforward elimination condition into another opportunity for Sleipnir's riders to demonstrate their specialized equipment.

Freya continues fighting after abandoning her original aircraft, using her wind techniques against Kogarasumaru and later confronting Onigiri as the match progresses.
