Canaan is the main character of the series, a mercenary currently operating in Shanghai. She was the only survivor of a village destroyed by war in the middle East before being found and trained by Siam, who has her adopting the name Canaan. She developed a mutual respect for her mentor during the course of her training, but after he was killed by Alphard, her mind is consumed by the thought of revenge and often gets serious whenever she sees Alphard.
As an elite mercenary, Canaan is also a skilled marksman and an expert of combat. She possesses the ability known as synesthesia which allows her to concentrate and combine her senses. She uses this ability as a radar to locate others, to hack into mechanical systems, and to dodge/deflect bullets easily. If she overuses it, however, her strength will be exhausted and she will collapse. Canaan has blond hair and hazel eyes, but whenever she uses synesthesia, her eyes turn red.
As she was living in isolation for most of her life, she treasures the friendship with Maria Ōsawa, the first friend she has in years, to the point of prioritizing Maria's safety above all else and ruthlessly killing anyone she deems as a threat to Maria. Despite this cold-blooded nature, she enjoys going out with Maria as well as living a normal life.
