Hyunckel's parents were killed in a monster attack, but one of the monsters took him in and raised him like a son. When Avan killed Hadlar and Hyunkel finds his adoptive father dead, he secretly holds a grudge against Avan, who he believes killed his father. Hyunkel then becomes Avan's first pupil but, after graduating, unsuccessfully tried to kill his teacher with a technique he invented himself, Bloody Scraid. He was then taken in by Myst-Vearn who brought him up to be General of the Immortal Army, one of the six main armies under Hadlar and Vearn's control. After discovering that Hadlar had killed his adopted father instead of Avan, he joins Dai's party. Hyunkel originally used a demon magic sword that could transform into armor (Amudo), but Dai broke it when he was fighting Baran. Ever since then, Hyunkel has been using a spear with the same properties and created by the same person. Hyunkel can use all the basic Avan techniques also in addition to Demon Puppet Grab (He learned it from Myst-Vearn). Due to changing his weapon from a sword to a spear, he had to learn Avan's elemental techniques for spears (Avan developed techniques for all sorts of weapons). The new spear techniques he learned are called Thundering Ground Flash (equilavent to the Earth Slash), Echoing Sea Flash (equilavent to the Sea Slash), Sky Flash (equilavent to the Sky Slash). His strongest attack is the Grand Cross (a huge cross shaped attack that utilizes the user's entire life energy storage into 1 massive attack).
