Leveling Up with Monsters: Shadow Sovereign

About Leveling Up with Monsters: Shadow Sovereign

Fifty years after a colossal, monster-infested tower appears on Earth and traps humanity within its walls, a powerless young man merges with a forbidden creature and gains an unprecedented power that binds him to a secret mission. Cut off from the outside world for five decades, all of humankind lives confined inside this towering structure, surrounded by dangerous beasts at every turn. For those trapped within, there is only one path to freedom: awakening the abilities of a hunter and fighting all the way up to conquer the hundredth floor. Yushi is born on the first floor of the tower, knowing no other life than the enclosed world inside it. Determined to survive and move forward, he puts in more effort and works harder than anyone else around him. Yet despite his relentless dedication, he remains completely unawakened and utterly powerless in a society where strength as a hunter is the sole means of escape. His stagnant existence takes a sudden turn when an unexpected encounter alters his fate. A forbidden monster known as the Shadow comes fleeing down from the upper levels of the tower, and Yushi merges with the creature. Through this fusion, the once-powerless boy awakens to an extraordinary and unprecedented power that sets him apart from ordinary hunters. This newfound strength, however, comes at a steep and complicated price. Alongside his abilities, Yushi is bound by a secret quest that turns the fundamental duty of a hunter upside down. Instead of slaying the creatures that populate the tower, his hidden directive orders him to fight alongside monsters rather than destroy them. Word of this rare power soon draws unwanted eyes from high places. Coveting the abilities of the Shadow for themselves, members of the nobility mark Yushi as a target and send deadly pursuers after him. Forced on the defensive, he can neither rely on normal allies nor openly reveal the nature of what he has become. Caught between the hunter mandate to clear the floors and the secret order to ally with monsters, Yushi must carefully navigate conflicting missions while evading the lethal forces hunting him down. As he fights to stay alive against relentless pursuers and climbs into greater danger, his journey pulls him closer to uncovering the hidden truth behind the tower itself.
