Leveling Up with Monsters: Shadow Sovereign

Half a century ago, Earth was swallowed by a colossal tower, trapping humanity in a brutal struggle for survival. For the desperate, the only escape lies in awakening as a Hunter and conquering the 100th floor. Yushi, born into the lowest strata of the first floor, has spent his life as the weakest of the weak, unable to unlock any powers. That is, until a forbidden entity known as the Shadow fuses with his soul, granting him a terrifying, otherworldly strength. However, this gift carries a twisted mandate: he must ally with the monsters he was meant to hunt. Now, hunted by ruthless nobles who crave his unique power, Yushi must navigate a treacherous path of betrayal and evolution. Will he become the tower's ultimate savior or its most feared nightmare?
