Blue Wolf (青いおおかみ, Aoi Ookami) is a character in Return to PoPoLoCrois: A Story of Seasons Fairytale. A mysterious wolf that came to Prince Pietro's aid in his time of need, and just never stopped helping him since. Fiercely loyal, and answers to the name "Blue." No one knows where it came from, but one thing is for certain: it is absolutely a friend, and somehow seems as dedicated to Prince Pietro's cause as any human would be. And the feeling is mutual: when Pietro was on the verge of despair, Blue was the rock that helped him keep a cool head, reminding him that there's always hope, and that hope can sometimes take on some very unusual forms.
