Jason wonders if his luck has finally turned around when he discovers he will inherit a luxurious home infused with ancient magic and a sizable fortune from a relative he'd never known existed. Of course, there's a catch. His younger brother and his cousin will inherit equal parts of the inheritance and it is stipulated in the will that they must live together first before they gain possession of the estate. All three of them are potential White Knights with the rare ability to practice advanced white magic. They must learn to use their new power and defend themselves from a secret organization that is armed with potent, black magic.
