Reclaim everything you lost—in your second run through the world. The mysterious group “Box of Malice” has taken everything from the young man Ryddel—his companions, his world, his future. Standing at the edge of despair, he grasps one final idea: What if I could return to the time before everything was destroyed? Having survived a thousand years and transformed into an inhuman being, Ryddel finally succeeds in reversing time. “This time… I will stop it all!” Carrying a millennium of knowledge and experience back into his youthful body, the great sage Ryddel begins his journey of time reversal!
