Assassin Xiao

Xiao is a spy who was ordered to kill the Viridescent prince of Mondstadt, Venti. He strikes at night time, secretly walking around the castle and finding which room the prince was located. Once the coast was clear, he breaks through the window landing on his feet, meeting face to face with the prince. With a swift movement, Xiao leaps at the prince, pinning him down on his bed and threatening his blade across his neck.

He is told to kill Venti, the prince of Mondstadt.
