Musca is a supporting character and is the youngest child in the royal Noctitcus family. She appears to be bratty and snotty since she is used to getting whatever she wants whenever she wants. She also has an odd habit of talking in third person every once in a while. Musca used to look down on Belca with scorn and disliked him in the beginning of the series. However, as the series progresses, her opinion of him changes and she often refers to him as "Commoner's Child" or just Belca. She tries to make contact with him now since Orcelito appears to be ignoring her in her opinion and somewhat looks fondly to Belca. Earlier, Lagen had been poisoning Musca was a less harmful poison that only made her feel sick and feverish. Ossan, her self appointed "knight" realized this and told her the truth. Musca realizes this and runs away. (Source: Wikipedia)

Belca Noctircus is the third prince in the royal Noctirous family and is the main protagonist. He is not of pure royal blood like his two older brothers, Hector and Orcelito and younger sister, Musca. Since his father had an affair with a commoner woman, Belca is often looked down with scorn and pity. He is often insulted and made fun of and is disliked by his younger sister Musca. Belca hates the castle life and wishes to leave but he admires his elder brother Hector and hopes that if one day the kingdom is ruled by a "weird guy" (Hector) and a "serious guy" (Orcelito) he might just want to stay. However, before Hector's coronation ceremony, he is apparently killed by his chronic disease. A while later, Belca discovers the conspiracy behind his oldest brother's death and is now being pursued by the elders. He now travels with Eco and often has to cross-dress as a woman called Mariebelle to avoid being captured. Belca is also often confused and surprised by a lot of things such as warm food outside of the castle and how much his ring is worth. He is skilled with the sword and at the start of the story he hates the Amontel since he believes that they indirectly caused Hector's death. As the story goes we see that he is a kind and naive young man who loves his friends and siblings very much, and that he will never let them suffer for him. (Source: Wikipedia)
