Chapter 4 (Manga)
Ekaterina "Katja" Kurae is a young but powerful Qwaser who controls the element of copper.
She was sent to St. Mihailov Academy as a transfer student from Russia; due to Miyuri Tsujidou wanting a foreign friend of her own to compete with the bond that Tomo and Mafuyu shared with Sasha.
Ekaterina is a very young girl, at the age of no more then eleven, she has a gothic Lolita look to her, as she has very small breasts, and is usually seen wearing a black maids outfit, having her hair tied in very long pig tails, which are held together by black tape, as well as long hair, covering all of her forehead, and her ears as well.
With Russian ethnicity and being no more than eleven years old, Ekaterina has the beauty of a doll and as such is admired and regarded with awe by other girls. Fully aware of this, she presents herself as extremely shy, innocent, and child-like in public and amongst strangers; adopting the habit of addressing herself in third person to further her "cuteness."
Her true colors, however, are of that of a domineering, arrogant, prideful, and almost malicious queen. She uses her "innocent" image to seduce other women, particularly those with a lolicon or lesbian fetish, and emotionally and sexually dominates them into being her devoted Maria's. Ekaterina also refers to the gynoid as "mother" for reasons currently unknown. Also when Anastasia is destroyed, she gave her a burial and cried over her grave so she seems to sincerely believe she is her mother.
Ekaterina is a powerful Qwaser who wields the element of copper, which usually makes her gain control and manipulate electrical wires and redirect their flow to electrocute and incinerate her foes. Due to her frailty as a little girl, she uses an archaic gynoid, Anastasia, to physically attack her opponents and defend herself. Ekaterina also refers to the gynoid as "mother" for reasons currently unknown.
