Shadow Guard number six, whose name is akin to the master of infiltration, Wind Master. His nickname is Sixth.
He served the Emperor as his personal bodyguard, alongside their leader, Master Art. Sixth's duty alleviated to be the Imperial Prince's bodyguard as soon as the young prince learned to walk by himself. His coworkers teased him that the Emperor was angry with him and demoted his rank to supervise the hated and ill-bringer prince, The First Prince, Prince Danial. Initially, he also thought so.
The Emperor loathed his son and unceremoniously abandoned him to the farthest place within the palace. The palace was the Cold Palace. The young prince at that time was only five years old.
