(Synopsis from the back cover):
«“May all that you wish to protect burn to ashes…”. Having witnessed the staggering power of the Shadow Monarch, Jinwoo can’t wait to level up and reach those heights, and what better way to do so than to mobilize his army of soldiers against an S-rank dungeon’s worth of giants? Saving a country abandoned by the rest of the world has its benefits—international renown, the expansion of his guild, an invitation to the most prestigious hunter conference in the world—but perhaps the most unexpected bonus is a run-in with another Monarch who brings not-so-welcome tidings. If he’s to be believed, a war is coming that not even Jinwoo is strong enough to stop…».
The attack of the giants is quite reminiscent of the anime Attack on Titan.
Jinwoo sometimes uses violence and threats to test whether someone is telling the truth. He is also extremely violent when seeking revenge (he brutally beats someone for kidnapping his friend).
"I will protect my family even if it means becoming an enemy of all the Hunters." Loyalty to family and close friends, to his country, and to people he respects.
Fast-paced and addictive, very easy to read.
When Jinwoo kills a human opponent to exact revenge, he does use his Soul Extraction ability to create an obedient and loyal shadow. But he then orders the new shadow soldier to sit or lie in complicated, difficult, exhausting, and sometimes painful positions. All for revenge. You could say he tortures him even after death.
There is a torture scene. They dedicate themselves to punching the unfortunate man and then healing him with magic so they can punch him again.
