Fai Xie's Links
Sees him as a younger sibling. It was against his mercenary code to lie to his client about Enki's death and he feels he was too merciful, but he has grown attached to Enki. Xie cares deeply about Enki and only wants to make him at least content with life. Though Enki does not see it, Xie struggles with feelings of inadequacy in his care and support of the young demon.
Looks up to him a bit. Xie is powerful and emotionally stable where Enki is impulsive and troubled. Though, both of them have similar pasts, leaving at a young age. Enki was once caught by Xie for a contract killing, and after Xie listened to his story and emotional rant, he granted him a pass. Most of the world presumes Enki dead as Xie lied to his client about killing him. Xie now offers to teach Enki more combat skills and provide strong emotional support. Enki considers him a big brother, but also may or may not have a crush on him.
