Before his betrayal, Enki was close to Samon, often training together when they were younger. Enki did not seem to mind Samon's presence as he was training He used pat Samon on the head when Samon was still a child. As they grew older, Enki became a prison guard, with Samon working under him. They remained close till Enki betrayed Nanba Prison and killed an inmate. Enki then acted coldly to Samon, calling him weak and not even hesitating to brutally beat him up to get Samon out of his way.
