Beginning of the series

Aware of Majeh's incredible power, the council of the Next World declared that he was too dangerous and placed 3 seal's on him, causing Majeh to revert to his teenage form and suppressing the vast majority of his powers. However, even in his teenage form, Majeh is still an incredible martial artists who has no trouble in defeating most of his opponents as well as any martial artists he may come across in the living world. Samhuk, A member of Hell's greatest inspection organization, is observing Majeh's movements as he was ordered to by the King of Hell. Early in the manhwa, Samhuk is caught by Majeh and forced to be his slave or die by his hand. Samhuk, being told of Majeh's power, reluctantly agrees and ends up as a slave and a punching bag for Majeh. It is soon discovered that a rift between the two worlds has opened letting demons crossover and Majeh is ordered to hunt them down.

While on his task to rid the world of the newly freed demons, Majeh is ordered to return to Hell where he learn of a new calamity has occurred and Hell's most wicked Demons, those who resided in Moorim, have escaped into the world of Mortals. However, because the escaped fiends are malignant spirits and evil they must find the body of a recently deceased martial artist to fully utilize their lethal martial arts. Majeh is tasked to arrest these formidable enemies to which He refuses.

The King of Hell, with not other choice, tricks Majeh into going back to his preserved body. Upon his return to the mortal world into his old body, Majeh reverts to his teenage form, due to the sealing spell that was placed on his spirit in the next world. Now back in the mortal world, Majeh has no choice but to complete his task, but is now severely disadvantaged due to his body being that of his teenage years.

Martial Arts Tournament Arc

Shortly after being returned to his body, Majeh meets Chung Poong, a skilled martial arts disciple who is constantly paralyzed with fear in battle, and Dohwa, a female fighter who specialized in the art of poisonous needles.

Just for fun, Majeh decides to accompany them to a martial arts contest which is for fighters under the age of 15. Dohwa, being older, is unable to participate due to the fact that the contest for martial artists over the age of 15 had already finished its registry a day earlier to their arrival. Majeh, his natural state being suppressed to that of a teenage boy, enters the contest with Chung Poong. Also entering the tournament are five martial arts prodigies.

These martial art prodigies are as follows: Crazy Dog (martial artist, no affiliation), Young (assassin, Mooyoung Moon Sect), Dohak (monk, Sorim sect), Poong Chun (Shaman, Shaman Sect), and Baby (?, Blood Sect). As the tournament progresses, Majeh meets and learns about some of the prodigies and somewhat of their backgrounds. Meanwhile, in the backgrounds of the tournament, it seems that there are people undermining the tournament to ultimately cause a rift between the light and dark sects to put into motion a possible war between the two factions. The tournament itself if being held by one of the light sects and one if it seminaries Mo Young, a good man who believes that there are forces that are trying to start a war in the world but is unsure to what end.

After two day of the tournament, two of the five prodigies, Poong Chun (defeated by Majeh) and Dohak (Defeated by Crazy Dog), and as well as Chung Poong were eliminated from the tournament. The next fights were Majeh versus Crazy Dog, and Young versus Baby. The fight between Young and Baby resulting in Young resigning stating "My senses are telling me it would be a mistake fighting you." The fight between Majeh and Crazy Dog does not finish as the tournament is interrupted by one of the Moorim demons. Crazy dog is killed by the demon when he attacks him for interfering in his and Majeh's fight.

The fight that ensues is the hardest that Majeh has had yet in the Manhwa. And it is soon realized the power gap between Majeh (in his current form) and the Moorim Demon. Mo Young attempts to intervene but is quickly out matched. Samhuk leaves and informs the King of Hell of the situation and the king informs Samhuk that hope is not lost, because as Majeh gets closer to the line between life and death, the special seal that limits his power weakens and Majeh is allowed to return to his adult form. The result is that the Moorim demon is no match for Majeh in his adult form.

Missing martial artists

After the martial arts tournament, the assassin prodigy, Young, tags along with Majeh to find missing martial artists while Dohwa and Chung Poong go on a side mission to find a magical tablet that will help make them stronger. Majeh and Young uncover the crimes and plans of an old group called the Sa Gok, a group thought to have been wiped out, this group plans to rule the world by eliminating both the White and Dark Sects, they were planning new plots to go on with their task. The Sa Gok had turned the missing martial artists into zombies and would use them to start a Great War between the "good" and "evil" sects in Korea.

Majeh then dragged Young out to Devil Mountain to investigate rumors of a tomb recently found there. This is where the title King of Pa Chun first comes up, a legendary swordsman from 300 years before who rocked the martial arts world. The funny thing is that Majeh happens to know exactly where the King of Pa Chun and his legendary sword was buried and it is not in Devil Mountain. Majeh eventually reveals to all of his fellow treasure hunters, including Chung Poong and Dohwa, that the rumors of a tomb and treasure were an elaborate trap.

Majeh was able to stop the Great War cold then left to continue hunting down the remaining six escaped fiends. The first one he encounters is the old man that interrupts the young dragon tournament. He encounters another fiend while on a side errand for the martial arts leader and helps the monk it was trying to possess destroy the fiend completely. He encounters two more on Raven Ghost Ilse leaving only three (the second one was defeated by the "heaven sage" monk at his death) more for him to find. The only problem is that to get enough power to defeat them he has to die.

Main characters

• Majeh (마제)

The main character of the story, Majeh is a very skilled swordsman and an extremely powerful warrior. Majeh is the emissary to the next world and is charged with ferrying souls from the mortal realm to the land of the dead, be that heaven or hell.

Originally, Majeh was fated to go to the Morim, a place where swordsmen of the mortal world who cannot be judged are placed - swordsmen who honed their skills through unorthodox means. Once a swordsman reaches the pinnacle of their art, they can no longer be judged and are placed in the Morim. When word of Majeh's arrival reached the other residents of the Morim, they targeted him. However, Majeh dispatched every resident, except for one, of the Morim that challenged him that day. He was finally challenged by Murin himself, and an epic battle ensured, where both fighters used Heven Slayer Ki, each believing themselves to be the only possessor of such ability. Murin quickly defeated Majeh. Before Murin could kill Majeh, the King of Hell swoops in and ends the fight, and majeh becomes his envoy, as to keep Majeh and Murin apart. As such, the King of Hell deemed him as threat to the Kingdom of Hell and Majeh was made the ferryman of souls between the mortal world and land of the dead ever since.

Majeh bears the Mark of the Super Human Seling bol, a strength sealing gold mark which seals away a great deal of Majeh's incredible power and changes him back into a young boy. The method to outright remove the seal is for Majeh to die; thus, the closer Majeh comes to death, the weaker the seal becomes.

When evil spirits started escaping into the mortal world, the King of Hell had Majeh hunt them down. However, during the confusion, the seven strongest members of the Moorim escaped to the real world and so the King of Hell returned Majeh to life to hunt them down. During his travels Majeh became entangled in a second plot to overthrow the martial arts world masterminded by a long thought dead enemy known as the Sa Gok.

After beating the Sa Gok, Majeh loses his memories and becomes a courier called Yong. He works as a protector for the courier goods. He is later found by Samhuk whom majeh can no longer sense or can no longer recognise. Samhuk sends Majeh off to speak to the trade demon. He encounters her, and after trying to exchange his soul for his memories, but as Majeh's soul is owned by the king of hell, she can not possess it, and thus hires men to kill majeh, when he is in a dream, gain his past memories.

As Majeh regains his memories and awakens, he encounters Chung Poong, Dohwa and young all protecting his unconscious body. He kills the trade demon easily, and then beings to hunt down the remaining demons. Little does he know that Murin, the strongest fights from the Murim level of hell, has escaped, and is hunting down artifacts to make him the strongest. He is posing as a reincarnation of the Dalai Lama.

Joined in his travels by novice martial artists Chung Poong, Dohwa Baik Majeh, and later Young a prodigy of the Mooyoung Moon martial artists. Majeh hopes to stop the Sa Gok, and defeat the escaped souls of the Moorim.

Later on in the manhwa we learn that Cerberus himself is also a demon when he had to transform back to his original form to defeat his enemy on Raven Ghost Isle.
