A Demon sword of the Empire, whose form is a flamberge.
Voiced by: Satsuki Yukino (Japanese); Clarine Harp (English) A Demon Sword of the Black Flame, who, like Aria, can take human form. In her human form, she is morose and taciturn. She was in Charlotte's possession but may have come from Siegfried. She transforms into a sword by chanting "Shake off your slumber, cloak yourself in darkness, bring yourself the end and kill God" (眠りを解け。闇をまとえ。結末をあなたに。-神を殺せ?).
