Zai is an expert thief, a rogue agent who works for no one but himself. He is a short, thin man with a dark complexion, hair, and eyes, and easily forgettable features. He prefers his solitude and soft classical music, but his life changes one day when he becomes the victim of another master thief. Now he must associate with the other criminals who share his profession and use his skills to track down this rival thief. Zai’s talents include lock picking, hand-to-hand combat, throwing knives, and subtlety. He would much rather evade enemies altogether, but he is often forced to fight. It is eventually revealed that he was the son of rich parents and lived in a luxurious manor, but he was placed in one of the city’s worst orphanages when his parents died in a car crash. All of his thievery was only in a vain attempt to recreate the life he used to have.
