Amber's ability is chronal manipulation, which includes temporal freezing of time and rewinding of events to an unknown degree. Elaborate usage of her power enables her to gain knowledge of future events, and then respond to them accordingly. Once time has been frozen around her, she can also pull other people out of the frozen time stream, while those still under her ability's effect will no longer detect her presence or movement. Her remuneration is aging backwards, making her appear frequently younger. Amagiri has warned her that she cannot use her ability flippantly, saying that she can only pay off her contract to a certain extent.[5] Her overall objective is to destroy the Hell's Gate in a way that doesn't erase every Contractor from existence. Amber cares deeply about and has feelings for Hei, in spite of him believing her to be a traitor. To emphasize this, she often goes as far as to order her subordinates to avoid fighting Hei, even though this usually veers close to compromising their given mission objective. She maintains the mysterious Meteor Fragment retrieved from PANDORA's Gate Research Facility in her care in a pouch slung across her shoulder. After showing him all that he would have if he used his power to close off the gate (her, his friends, and his sister), she reveals the true extent of her feelings for him by sacrificing herself so that Hei may pursue, instead, the option of shutting down the particle accelerator that would destroy the gate instead of sacrificing Japan or all Contractors. In the Ryuusei No Gemini arc, when Misaki acesses the "Files of the Future" she is seen behind her before disapearing when she turns around.
