For the last four years, humanity has been facing its greatest challenge yet—a trial known as the Crucible. This harrowing ordeal has tested the mettle and determination of individuals, weeding out the weak and transforming the survivors into warriors.

They have been forced to conquer dungeons and battle horrific creatures with magical powers so they can gain abilities of their own.

However, the Crucible was merely the beginning.

As the trial concludes, the survivors find themselves on the precipice of an entirely new realm—the Endless Planes. Here, magic thrives, and ancient forces shape the destiny of worlds. The Endless Planes, a vast and diverse realm, is home to countless kingdoms, mythical creatures, and formidable challenges.

Among the survivors is Kaito Bao, who has been marked by the scars of the Crucible. Once a loving father and husband, he has lost everything dear to him. And now, all that drives him is his unending desire to hunt down more monsters and punish them for ripping his family away from him.

In his obsession, he has acquired powerful abilities, accomplished incredible Feats, and gained rare Titles.

Join Kaito as he explores Serpent's Way, the bottommost world of the Endless Planes, where all people must begin their climb to the top.

For mature listeners.
