Belca Noctircus is the son of a commoner and the King of Noctircus. He is the third prince in the royal Noctircus family and stands third in line for the throne. Shortly after returning from abroad, his brother and the crown prince of Noctircus, Hector, reveals his ambition to establish peace with the Amonel, a race regarded as monsters, but mysteriously dies from a chronic disease. Belca and his other older brother, Orcelito, uncover the conspiracy behind Hector's death, and Belca is nearly killed as a result. However, he is saved by a wandering bard and scholar named Eco. Meanwhile, Orcelito is taken by Lagen, whose son, a young nobleman, locks him up and manipulates him to carry out Lagen's bidding and wishes.
