The Legend of Vivid

The artsy version, from the bottom's point of view:

Vedvitt, a mysterious family that appeared out of nowhere in the 16th century and vanished mysteriously in the 19th.

Vedvitt, a family that believes in profit, where the family's interests come before everything else.

Vedvitt, a family unafraid of death, yet always walking its edge.

Vedvitt, a family that made a pact with a witch and is known by the world as the guardians of the Golden Land.

Well, my name is Yaxiluo Gal Vedvitt, and I will lead my pathetic family to the status and prosperity it deserves.

The author's snarky version:

It's really just a gorgeous little pretty boy being used by the family's old, immortal bastards to reclaim its honor.

The boy was raised by an immortal old witch named Sarah Brightman, so he picked up a few bad habits = =. Gambling, drinking, cards, smoking: he loves them all. So that immortal old she-devil Sarah Brightman decided to lead my little Gal astray...

CP and all that is up in the air. For now, it's an NP relationship.

The Mafia families and so on are all American. Don Corleone from The Godfather is tentatively included.
