When I first started reading this series, I was quickly intrigued by the art style and the humor. Even though KOH is more or less action/martial arts based it has a lot of funny parts and I wouldn't count them as "comic-relief" but more like one of the essential flavors of the plot itself.
Moving onto the plot although it has similar elements which have been used over time, they have been used to create a unique world with interesting characters. Majeh is a messenger of death/soul reaper who has been assigned the task of collecting dead people's souls and bringing them to hell. In reality his powers have been suppressed by a seal and his physical body is preserved in the real world. Anyways the the ruler of hell aka the king decides to trick him into going back into his preserved body by lying that he will remove the seal so that Majeh can regain all his powers and then capture and bring back the evil souls that have escaped from hell. Majeh's unsealed form is more mature and older which provides more action during intense battles. However since he was deceived in the first place, Majeh starts off in a teenage form.
Besides, Majeh there are several other interesting, sometimes eccentric characters. Some of the important ones include Dohwa who is a good fighter that uses poisoned needles techniques and the other one is Chung Poong who belongs to a famed martial arts family and wants to redeem his honor (even though he is a scaredy-cat) by participating in a martial arts tournament. Majeh decides to join them both and more incidents and characters unfold.
The action scenes for this series are very good and it is a shame that it is not an anime. You can still enjoy them with the lack of animation because of the different techniques and the art itself.
Bottom line, this is a very good manhwa series that I hope to follow till the end. I hope others enjoy it as well :D
