The first confirmed Contractor, with her star's Messier code UB-001. She was originally a spy for MI6 with the codename February but later defected and joined the Syndicate, adopting "Amber" as her new name. She worked together with Hei and Bai in South America during the "Heaven's War", and founded her own organization, the Evening Primrose at that time. She went missing together with Bai and millions of other people when the Heaven's Gate disappeared, only to reappear later to fight the Syndicate with the rest of the strengthened Evening Primrose. Even after leaving the Syndicate, she chose to keep her codename "Amber," stating that she had grown attached to it.
