Adapted from the song "The Villainous Careers of the Young Lady and the Young Master," with some changes to the plot.
She is a cold-blooded, delicate young lady.
He is a proud young master who admires no one but himself.
Two years ago, a pair of siblings suddenly appeared in the martial world. Their names were known everywhere, but no one had ever seen them. They roamed the world, called no place home, and killed as if it were an art. People called them the "Twin Assassins."
But no one knew why they had come, why they drew their swords, or why...
they became both demon and Buddha.
