|First Appearance||Phase 1: For You, the Replaceable Ones|
She is currently serving time as a Class 1 Criminal (her crime is not public knowledge), but has been allowed to leave in exchange for volunteering as a research subject at the Geroy Level 4 Heavy Military Research Center.
That research center and the Russian government have not publicly released details concerning her mental capacity, so her talent and potential are unknown.
The range of her P3 level varies widely and is unstable. However, though it's unofficial and only happened once, she has supposedly surpassed the highest P3 level measurements of Miyao, the world record holder, by a considerable margin.
Koshka appears as an androgynous girl with long green hair. Her face is covered in scars and bandages and her eyes are never seen. She typically wears a brown dress along with a black jacket.
Koshka hates being near others. Her presence at the Public Bath meeting ground and friendship with other Gauntlet Knights is largely due to her love for the Selcom game WanyaDora and the advantages having friends would bring her in the game.
- Koshka (Кошка) is a Russian word referring to a female cat.
