One of the Valkyrie Servants. She has long brown hair and brown head wings. Her name is stylized as Geirskögul.
She was originally seen as part of the primary Valkyrie Lancer's Noble Phantasm. She is eventually given a name in the summer 2022 event, and functions as an alternate costume for Ortlinde Swimsuit Assassin, also given her own voice lines.
She was one of the Valkyries borrowed from Planet:Valkyrie, specifically Type-08.
