In a world divided between White and Dark, a desperate act of hope sparks the rise of something new.
White, a young man trained by three powerful masters, fails to defeat the overwhelming force of Dark.
Facing great loss, his masters use forbidden Arts to send his potential two hundred years into the past, sacrificing him to rewrite fate.
Unknown to each other, each master secretly embeds their personal wish into the transfer, forever altering the shape of destiny.
This is the story of Grey, a bastard born to a noble and raised as a commoner, a boy reincarnated in the world of White and Dark with White's potential.
On the eve of the annual monster hunt, everything will change for him.
