Canaan

Canaan is the titular character and protagonist 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 respect for her mentor during the course of her training, and later to Alphard as well (Siam's former student who she saw as an older sister figure). But when Alphard betrayed both her and Siam during a mission and left Siam to die, Canaan was consumed by the quest for revenge. Canaan gets serious whenever she sees Alphard. As an elite mercenary, Canaan is also a skilled marksman and an expert of combat, her weapon of choice most of the time being a Beretta Px4 Type G 9 mm semi-automatic pistol. She has the ability to use synesthesia to aid her in combat, viewing the world in different colors to tell enemies from civilians.[2] She is always seen with a red halterneck shirt and brown pants. On her left wrist, she wears a black tattoo that possibly completes a whole picture of a snake with the tattoo on Alphard's arm. She covers this tattoo with a layered red armband, which repeatedly gets ripped off during her fights.
