The only female member of Sleipnir, known as the "Spring of Life," Freya has distinctive cat-like ears atop her head. This feature initially puzzles Kazu before their match with Kogarasumaru. She also makes feline sounds and gets upset when Kogarasumaru inspects the planes, though Loki reprimands her for this behavior. Like Loki, she carries a sword, albeit a smaller one. During the match against Kogarasumaru, her plane runs out of fuel first. To escape, she transforms her sword into a special AT umbrella, allowing her to seemingly glide through the air.
Freya uses the umbrella both as a shield and an offensive tool, deflecting Agito's Fang barrage. Later, she attempts to fend off Onigiri on her new plane. Interestingly, she has her own fan club, mostly consisting of overweight otakus similar to Onigiri. After Onigiri is taken out by Ikki and Agito, Freya joins Loki on his plane. Standing beside him and over Ikki’s exhausted body, she sings: "Where did we come from? Who are we? Where are we going?" as Loki demands that Ikki answer these questions.
She teams up with Loki against Ikki and Buccha, primarily providing support. When Ikki activates his Null Wind technique, she falls victim to Onigiri’s trick and becomes unconscious, forcing Loki to save her and forfeit the match to Kogarasumaru. In the previous GST, her hair was notably much shorter than it is now.
As the sole female member of Sleipnir, Freya is the only known Wind Queen. Her R.E.A.D. battle level is 136, and as a Brain Charger, she possesses their innate abilities. Some of her tricks include:
Asgard’s Bifrost – Using her umbrella and a mechanism in her ATs, Freya can walk over smoke trails or even air itself, created by the planes during battles.
Dance of the Einherjar Sword – By rapidly twirling her umbrella above her head, Freya generates a powerful tornado capable of instantly tearing apart the plane they are fighting on.
Nibelheim Blizzard – This trick allows Freya to maintain her posture while performing "Dance of the Einherjar Sword," though its exact capabilities remain unknown.
