In a realm ravaged by formidable monsters and extraordinary powers, the land is fragmented into disparate kingdoms and villages. Among them, the Kingdom of Noor once thrived, defended by the powerful Shadow Clan. However, their might bred resentment, leading to a treacherous betrayal. The benevolent former King of Noor was overthrown and murdered by his exiled, malevolent brother, who, with the aid of enemy forces, seized the throne. He ruthlessly subjugated all families, but the loyal Shadow Clan resisted. Taking advantage of their dispersed state, the new king orchestrated a brutal four-year genocide against them, wiping out the clan with the help of allied kingdoms.
In a desperate act, two surviving members of the Shadow Clan entrust their infant son, Rox, along with a family heirloom bracelet, to a majestic bird, hoping to save him from the king's wrath. The parents are captured, but the bird escapes with Rox, carrying him to a remote, monster-infested island. The bird becomes Rox's guardian, raising him in its secluded nest. At five years old, Rox discovers and activates the mysterious bracelet, which projects a message from his deceased parents, revealing their agonizing fate and his true identity. Consumed by rage and surrounded by a burgeoning dark aura, Rox makes a solemn vow: he will unleash the same suffering his family endured upon the entire world.
