Neza is not just a King's Assassin, but she is also a demi-wolf - one of the most despised races in Talion. When a failed assassination attempt on the king leads to 3,000 Rebel Assassins escaping to Realm 397, on a planet called Earth, Neza is chosen to chase after them, take them all down, and bring back the King's Assassins who were taken as hostage. If she doesn't complete her mission before the High Mages gather enough power to simply obliterate Earth, she will be destroyed with the entire planet. To make matters worse, her only aid is the king's baker - an air-headed girl who only seems to hold Neza back - and twin brothers whose only power is to grant "opposite wishes" once a year.

This is a piece I was working on several years ago as a teen and just rediscovered it.
