Baby

Baby is one of the five child prodigies that attended the Martial Arts Tournament. Baby is affiliated with the Blood Sect, a group of fighters that masters the art of the Snake Hand Technique. He is the only character seen in the manhwa that has multiple personality’s residing within him. The personality of Baby is a kind hearted character that only cares for others and is not much of a fighter as his two counterparts are. When Baby is in danger or becomes injured Hyur come out in Baby’s place and handles all the dirty work. Hyur is more of an experienced fighter than Baby and doesn’t hesitate in killing his enemy’s when needed. Later in the manhwa another personality named Kwang is mentioned that comes out less often as the others do. Kwang is the strongest of the three personalities and only appears when Hyur gets into a situation or a fight that he has no chance of coming out alive.
