Cyan Vert, illegitimate son of the Duke and the empire's greatest assassin, is betrayed by the righteous brother whose shadow he's always lived in. But just before the fatal blow strikes his throat, Cyan awakes to find he's just a boy again. The young lord has been reborn, and this time, he's not going to live in anyone's shadow!

Cyan Vert, the best assassin of the continent, meets a pitiful death after having been betrayed by his own brother, whom he had trusted all his life.

"If I were given another chance at life, I would live it differently. I would only trust myself, and achieve all the things I want on my own without serving anyone else but myself."

That is how he was given a second chance at life. Cyan Vert, a shadow who lived for others, is no more. He will now pave a path on his own, for only him!
