Hereos and demons.

The story starts with a scene involving Virulent and his servant, Vicious and their monsters, against Commander Regret,Nawe and their own army. A gruesome battle ensues, and a child is left in the middle of the warfield. Commander Regret picks him up and decides to raise him as his own child, much to the dismay of his subordinates and the citizens.

In the small town of Ayles, Regret - who changed his name to Val- raised Regret (the child he picked up earlier) but was killed by a demon. This, Marden doesn't know, but the villagers do. Since day the child had been brought to their village, all the people already harbored hatred or at least annoyance in him. If not for Val, they would have never wanted his presence in their place. After Regret's death, Marden is forced to leave and head to the city of Adonis. He meets Sun, a girl searching the lands for his father, who had been missing since she was a baby.
