Prince Pietro (ピエトロ王子, Pietoro-Ōji) is the protagonist of Return to PoPoLoCrois: A Story of Seasons Fairytale.
The prince of PoPoLoCrois. He's beginning a new adventure into the foreign land of Galariland. 
Prince of PopoloCrois, with the blood of dragons running through his veins. Innocent, naive and selfless, he's seen as a role model throughout the kingdom. Has gone on adventures before with GamiGami, the White Knight and Narcia, and saved PopoloCrois (and possibly the world) on numerous occasions. Although he sees GamiGami as having a secret heart of gold, and considers the White Knight a role model and confidant, it's Narcia whose company he truly wishes to keep, having developed a significant crush on her over the years and always wishing he could work up the nerve to get closer to her.
