The Regressed Son of a Duke is an Assassin

Cyan Vert, the greatest assassin of the continent.

After having been betrayed by his own brother, whom he had trusted all his life, he meets an pitiful end.

If I were given another chance at life, I would live it differently.

A life where I would achieve all the things I want, and trust only myself, without serving anyone else.

That is how I was given a second chance at life.

The Cyan Vert, a shadow who lived for others, is no more.

I will now pave a path on my own, for myself!
