The story
One hundred years ago, Vampire King Duzell led a war against the humans and kingdom of Pheliosta, simply because he was bored. In the epic last battle, King Phelios defeated Duzell by using a powerful spell that uses the caster's life force as a weapon to destroy the enemy, but kills the caster in the process. As both lay dying, Duzell swore that they would be reborn in a century's time, and he would find Phelios' reincarnation and kill him.
Ninety-nine and a half years later, Duzell's spirit approaches a wildcat called a kyawl, offering a partnership, as the kyawl's kittens had been killed and the she-cat was seeking revenge on those who tormented them. Unfortunately, the kyawl killed an innocent man in the process, leaving a little boy, Roy, fatherless. The kyawl tells Duzell after she avenges her kittens, she would give birth to a son, and Duzell could take refuge in his body; however, she would sacrifice herself to stop the cycle of revenge.
