Majeh is a highly skilled swordsman and the main protagonist of the series. When evil spirits began escaping into the mortal world, the King of Hell restored Majeh's spirit to his perfectly preserved body, tasking him with hunting down these malevolent entities. Majeh bears the Mark of the Super Human Sealing Symbol, which significantly restrains his immense power. Upon revival, his adult form regressed to that of a teenager due to the effects of this seal. While searching for the escaped spirits, he meets Chung Poong and Dohwa Baik, who join him in his quest. As the story unfolds, more characters, both new and old, join Majeh on his journey. Alongside his extraordinary strength, swift speed, and superior swordsmanship, Majeh wields powerful techniques such as his renowned Pegasus Land Mines and Heavens Arrows of Judgment.
Majeh's true name is Ja Young Choi, revealed in volume 17 of the series.
