Miracle Assassins

Althea and Jameson are supposed to live in two separate worlds.
One a princess and daughter of a ghastly man while the other farms produce to feed the land.

But their worlds collide on troublesome days when they're separately visited by an alchemist that curses them to be under his control for the rest of their lives.

With the kingdom in a state of disarray from rebellions and citizens being murdered in broad daylight, the two struggle to keep their identities a secret as more and more aspects of their lives are revealed to each other.
