Endless sky and infinite space, the cosmos isn’t some paradise waiting to be found, it is full of darkness and danger, death and terror of the great unknown.

The age of cosmos exploration!

What does it feel like to be hunted down by the whole just for being overpowered?___For centuries, the realms feared one thing, the birth of a child under the Blood Moon. A cursed child with the power to destroy everything.Every two hundred years, it happens. And every time, the realms unite to erase that child before their powers awaken.But this time, the Blood Moon didn’t rise. And yet, the child was born.Kaizen, 18 years old, was believed to be powerless, an ordinary hunter with no magic or magic core. What no one knew was that his abilities had been sealed since birth. Not just one, but all five elemental powers, water, fire, earth, ice, and shadow.The same power that once shattered the balance of the world.After a near-death encounter, the seal breaks. His powers begin to surface—unstable, dangerous, and impossible to ignore. Along with them comes a system that forces him to evolve and grow stronger.Now, Kaizen must hide the truth, survive among hunters, and face enemies far beyond anything he imagined. Because if the realms find out what he really is...They won’t hesitate to kill him.They promised this curse would never return.They were wrong.
