Prince Pietro is the half-human, half-dragon prince of the kingdom of Popolocrois. After the evil GamiGami tries (unsuccessfuly, as ever) to take over the Kingdom, a mysterious girl named Hyuu appears in the forest near Popolocrois Castle, which is the beginning of an adventure for Pietro, his witch friend Narcia, and all their friends. Set following the events of the first Popolocrois game.

Pinon, the boy who flows within his body, the blood of the three races (the Dragons, the fairies and the humans), is actually the son of the Courageous One, Pietro. Pinon's encounter with a mysterious animal, Pap, opens up the door to an adventurous journey. He befriends Luna and Marco on the way. However, when he learns that his adventure will determine the fate of PoPoLoCrois, Pinon hardens his heart and leaves his friends. Unknown to him, this is an introductory chapter to a new adventure and Pinon will realise that he must resolve the bigger crisis present in PoPoLoCrois.
