The Lord of the Sapa Alliance and the leader of the Maninbang, one of the Five Hegemons of the Central Plains. He is the strongest expert and the undisputed number one of the Unorthodox Faction. He has pale, almost translucent skin, long hair that reaches his waist, and light grey irises. He is exceptionally tall, standing at about 190cm. His attire is incredibly flamboyant; he personally loves flashy things. It borders on the point of being garish. He wears robes embroidered with golden dragons and has rings set with jewels on all ten fingers, along with bracelets on his wrists. He primarily alternates between pure white and red robes, with red being his preferred color. He is notorious for his cruel and ruthless personality. He is obsessed with his own interests and is famous for always paying back what he receives tenfold. However, he is quite merciful and gentle toward things and people he cherishes (mainly those who pique his interest). His usual way of speaking is very soft and polite. He uses gentle sentence endings as if speaking to a child. He rarely uses profanity, preferring to use sharp-tongued insults instead, calling people things like 'pigs,' 'swordsmen,' or 'consumptives.' "In the end, it is humans who hunt and kill beasts."

The strategist of the Maninbang and the Sapa Alliance. His title is the Poison-Hearted Rakshasa. He is Jang Ilso's closest confidant. While his official title is Strategist, Jang Ilso often devises the more elusive strategies himself, so Gamyeong essentially functions as a personal secretary. He has a clean, refined appearance but always looks a bit tired. He does not get along well with the other high-ranking officials of the Maninbang.
