Imagine living your entire life as a hidden blade, a lethal shadow in the service of a family that barely acknowledges your existence. Meet Cyan Vert, the illegitimate scion of a powerful duke, and the empire's most formidable assassin. His loyalty was absolute, his skills unparalleled, yet he was nothing more than a tool, constantly overshadowed by the "righteous" brother who ultimately orchestrated his brutal demise. Betrayal stings, but a cold blade to the throat? That's unforgivable.

But fate, it seems, has a twisted sense of humor. Just as death's icy embrace tightens around him, Cyan isn't gone; he's back! Reborn as a boy, granted a miraculous second chance at life, he awakens with all the memories, all the searing pain, and all the deadly skills of his previous existence. This isn't just a do-over; it's an awakening. No more shadows, no more subservience. This time, Cyan will forge his own destiny, carve out his own legend, and make his former tormentors — and the entire empire — tremble. Get ready for an electrifying journey of vengeance, power, and ultimate self-determination in a world brimming with danger and dark fantasy. Cyan Vert is no longer just an assassin; he's a force of nature reborn, and his retribution will be absolute.
