Jinu

As the years passed, the guilt and shame of Jinu's misdeed began to manifest. Patterns crept across his body from his pact with Gwi-Ma while he saw visions of the demon king, hearing his voice in his mind and amplifying his torment. The more he regretted, the more the patterns spread. Eventually, the curse completed its work and Jinu became a demon bound in servitude to the very demon who had seduced him. Jinu spent the next several centuries aiding Gwi-Ma, though only when it served his own interests and was still haunted by the memories of abandoning his family. In time, Jinu encountered others like him, once-human souls who had made their own dark bargains and bore the same infernal patterns of Gwi-Ma, and these fellow demons became his cronies/group mates of The Saja Boys
