Yang

"Are you sure? If I die, the thing you're searching for will be lost forever."

A cool, calm and collected, details-oriented perfectionist. A skilled assassin who reads his opponents' moves and stays two, three steps ahead. He's not only good at close-ranged combat but is also a competent long-distance marksman. His personal life is shrouded in mystery but it's apparent he and Shuu have an antagonistic relationship.
