In a world where power is marked by glowing runes and monsters bleed through the fabric of reality, **Ryu** is nothing—an orphan with no name, no status, and no hope. Beaten down by nobles who wield their divine-given strength like a whip, he survives on scraps and stubborn defiance.But when a black rift—an anomaly unlike any ever recorded—appears in the dead of night, Ryu faces a choice: die a beggar, or risk everything by stepping into the unknown.Inside, he finds a nightmare. Kolasis, a legendary predator, hunts him through a twisted forest. The rules here are simple: kill or be killed. To survive, Ryu must forge himself into something sharper than the claws of monsters and crueler than the nobles who cast him aside.Yet the rift has its own secrets.
