Plot
In a world where hunters — human warriors who possess supernatural abilities — must battle deadly monsters to protect mankind from certain annihilation, a notoriously weak hunter named Sung Jinwoo finds himself in a seemingly endless struggle for survival. One day, after narrowly surviving an overwhelmingly powerful double dungeon that nearly wipes out his entire party, a mysterious program called the System chooses him as its sole player and in turn, gives him the unique ability to level up in strength. This is something no other hunter is able to do, as a hunter's abilities are set once they awaken. Jinwoo then sets out on a journey as he fights against all kinds of enemies, both man and monster, to discover the secrets of the dungeons and the true source of his powers. He soon discovers that he has been chosen to inherit the position of Shadow Monarch, essentially turning him into an immortal necromancer who has absolute rule over the dead. He is the only Monarch who fights to save humanity, as the other Monarchs are all trying to kill him and wipe out the humans.

Shadow Army
An immortal race that were resurrected by the power of the Shadow Monarch, which is an extraction of mana from both monsters and hunters. Unlike summons from other hunters, they are capable of growth, and speech, and have the highest amount of warriors, to the point that their sheer numbers surpass all the top guilds. There are multiple grades of shadow soldiers, including basic grade, normal grade, elite grade, knight grade, elite knight grade, commander/general grade, marshal/commander grade, and Grand Marshal grade. Only soldiers of commander/general grade can speak.


 * Igris
 * Igris, the Blood-Red Commander, is a high-ranking knight with exceptional swordsmanship and loyalty, holding the position of marshal that rivals Beru but overshadowed by Bellion. He kneels before his master after battles. Igris dislikes Iron’s foolish behavior in battle. Despitebeing a battle lover, Igris values education and argues with Bellion about Suho’s schooling. He is also one of the most powerful knights.


 * Beru
 * Beru is an ant shadow that has been extracted from the Ant King, a powerful S-Rank beast that overpowered all S-Rank hunters, which killed Goto Ryuji, and incapacitated Cha Hae-In, until Jinwoo managed to kill it. Beru is one of the most powerful shadows holding the position of marshal that rivals Igris but overshadowed by Bellion. He also has a very fond streak for Jinwoo's son, Suho.


 * Tusk
 * A high orc shaman shadow, previously known as Kargalgan, he is the boss an A-rank dungeon, as he nearly the defeated the Hunter Guild's strike team, he is also the first one to realized that Jinwoo was a Monarch. As an Elite Knight Grade shadow, his power is the same level of an S-Rank hunter.


 * Iron
 * Iron was the shadow of Kim Chul. During Jinwoo's fight with Baruka, a crazed Kim Chul attempted to kill Jinwoo only to be killed himself by Igris. Knowing that he would have a hard time defeating Baruka only with Igris' help, Jinwoo quickly extracted Kim Chul's shadow from his corpse and named him Iron. He is known for being an idiotic and dunced shadow, even copying Igris' habit of bringing a head to Jinwoo, much to the knight's annoyance.


 * Tank
 * Tank is the shadow of an ice bear that Jinwoo encountered during the Red Gate Incident. As a Knight Grade Shadow, Tank is about as powerful as an A-Rank Hunter. He was also strong enough to plow his way through a horde of demons like they were bowling pins and kill a Naga in one hit.


 * Kaisel
 * Kaisel is the shadow of Kaisellin, a wyvern that Baran used as his battle mount. After he killed Baran, Jinwoo extracted the shadow from Kaisellin's corpse and named it Kaisel, as he didn't remember the wyvern's original name. Unfortunately, due to the fact that Kaisel was only good for flying and not fighting, Jinwoo rarely ever used him as the story progressed and only ever summoned the wyvern whenever he needed to travel somewhere by air and couldn't use Shadow Exchange.


 * Bellion
 * Bellion is a servant of Ashborn and the strongest shadow in existence, holding the position of Grand Marshal. Bellion was born eons ago from the fruit of the World Tree, a mystical tree so large that it could blanket the entire sky with its branches alone. Following this, he became Ashborn's lieutenant, a position that he retained after his death, and was the first shadow soldier to ever be created from Ashborn's power.
