Leonel, 27 years old, son of the wealthiest man in Britain, found himself in the body of an abused, affinity-less, hybrid prince, demon-human of the demon Kingdom. His uncle, the demon king, sent him to the human kingdom under the pretense of protecting him, but it was all a ruse. Assassins were sent to kill him, as the king feared he was a threat to his throne. On the brink of death, Leonel discovered new powers within himself. A spirit companion, a dual affinity for Light and dark magic, and a demonic eye - all rare and coveted. With new power at his disposal, Leonel set out on a journey to reclaim the demon kingdom. Along the way, he'll face many challenges and will have to decide what kind of mage he wants to become. Will he use his powers for good, or will he succumb to the darkness within him?
