Prince Pietro of PopoloCrois Kingdom inherits dragon blood from his Ryu clan mother, Queen Sania, making him half-human and half-dragon. This unique lineage grants him special abilities tied to his draconic heritage, with the potential for significant power awakening. His dragon blood shapes his physical capabilities and his role in bridging races. At age ten, learning his mother believed dead is actually comatose, Pietro sets out with forest witch apprentice Narcia to rescue her soul from the underworld. This first quest introduces allies like the honorable White Knight and eccentric inventor GamiGami Devil. Pietro's defining traits are compassion and a strong sense of justice, prioritizing others' welfare. His bond with Narcia evolves into a central romance, marked by shared dates and her affectionate gestures. A crisis strikes at age twelve in "Poporogue" when PopoloCrois is transported to another dimension and his father, King Paulo, vanishes. Pietro embarks on a mission to find his father and restore the kingdom, navigating dream worlds and facing new threats, testing his resilience and leadership. By fifteen in "PopoloCrois Monogatari II," a matured Pietro confronts a goddess threatening the world with ancient tablets. His romance with Narcia deepens, their emotional connection becoming a core narrative pillar. The 1998 anime, set post-first game, tests Pietro's compassion. Hyuu, a Wind Kind girl arriving due to GamiGami Devil, and her companions steal Pietro's dragon powers. Allying with GamiGami Devil, they usurp the kingdom, forcing Pietro into exile. Reclaiming his throne requires personal growth, forging new alliances, and demonstrating forgiveness even towards his betrayers, emphasizing his commitment to understanding and racial unity. Later adventures include interdimensional travel to Galariland in "Return to PopoloCrois: A Story of Seasons Fairytale," balancing quests with farm life while seeking a way home. As an adult king, he marries Narcia and fathers a son, Pinon. Post-marriage, he undertakes diplomatic missions, like investigating disturbances in Necrosia at the Fairy Queen's behest, confronting adversaries such as the apostle Deimos. Pietro wields the Dragon Sword throughout his journey, a weapon evolving in power alongside him, often enhanced by collecting Dragon Orbs. His combat blends traditional swordsmanship with strategic positioning for back attacks or sacrificing turns for greater impact. His narrative consistently involves love, racial harmony, and the courage to protect others.
