Description
Pietro is the prince of the kingdom of Popolocrois and the central character of the original anime series set in that world. He is the son of King Paulo and Queen Sania, and because his mother belongs to the dragon clan, dragon blood runs through his veins, making him part human and part dragon. He is usually shown as a boy of about ten years old with blond hair, though later chapters of his story depict him as an adolescent and eventually as an adult king and father.

At the beginning of his story, Pietro believes his mother has been dead for a long time and is startled to learn that she has been found in a coma. This event sets him on his first major journey, as he sets out with the apprentice forest witch Narcia to save his mother's soul from the underworld. His early adventures also involve the recurring antagonist GamiGami Devil, whose schemes open a dimensional portal and bring the mysterious girl Hyuu into the kingdom. Through his encounters with Hyuu and her guardians, Pietro learns more about his dragon heritage and the power he carries, and he must face those who wish to take that power for themselves.

Personality-wise, Pietro is caring, kind-hearted, and deeply values friendship. He is humble and unassuming despite his royal standing, and he is described as innocent, naive, and selfless, which makes him a natural role model within the kingdom. He is also loyal, fun-loving, and good-natured, with a personality that does not allow him to refuse when someone asks for help. His sense of justice and his love for his family and friends are the main forces that drive him forward, and while he starts off somewhat young and inexperienced, he becomes noticeably more courageous and confident as his adventures progress.

His closest relationship is with Narcia, the apprentice forest witch who accompanies him on his journey; the two share a strong bond, and Pietro develops romantic feelings for her that begin during their first adventure together. He is also supported by other allies, including the wandering White Knight and the forest witch Guilda. Even his relationship with the bumbling GamiGami Devil is notable, since the villain is more of a recurring troublemaker than a truly cruel enemy and at times becomes something closer to an ally. His parents, especially his mother Queen Sania, are central to his motivations, and in later parts of the story his role expands as he rescues his father from a dream world and confronts a mysterious force threatening the entire world.

In terms of abilities, Pietro carries the inherited power of the dragon clan through his mother, and in the original anime this dragon power is a significant part of his identity. He is a capable fighter who wields a dragon sword with consistent attack strength and resistance to special attacks, and he can also use magic, including healing spells and area-of-effect attacks, which makes him a versatile fighter among his companions. As he grows older, he matures from a young prince into a heroic leader, and in the later anime series, set years afterward, he appears as an adult figure remembered as the courageous hero whose son Pinon becomes the new protagonist and carries on his legacy.
