Dungeons are appearing all over the Earth. The skies are darkening as the dungeons emit more and more blackness that threatens to block out the sun entirely. Humanity is scrambling. Slayers race to close every dungeon that appears. Slayers were once normal people, but they have become special. At age 16, Rebirth unlocked their inner potential.Tad Harrington is an unlikely hero, and yet, the morning of his Rebirth has arrived. Bullied relentlessly in life and at school, he looks to his rebirth with both hope and dread in equal measures. His whole life could change in an instant - he could be gifted with fame, money, and power...Only one fact stands in his way - 99% of Rebirths are duds.And he's never been that lucky.He is right about one thing: his whole life is about to change, though not in the way he expects. In a world where everyone else has power gifted to them, Tad gains a unique ability that allows him to level up. He will have to climb through all the ranks, earning every shred of strength he can grasp, or die trying.

The Infinite World: ever-changing and ever growing. New nations and races rose and fell almost daily. New Classes were discovered, and old ways were lost.

Monsters and beasts roamed the earth and were slain by soldiers and adventurers who were, in turn, killed by stronger threats. Heroes and villains created new epics and were forgotten when their successors appeared. This was the way of the Infinite World.

Summoned into this chaotic place, a young boy with no name and no past must learn to survive. Bound to a master who doesn't care whether he lives or dies, he must become stronger. The question is: how? Do the people around him value him for who he is or merely for what he represents? The world holds endless possibilities, but only time will tell what the future holds for the boy.
