Destined Hearts is about a cocky and carefree girl who has suffered a terrible past, along with her brother and her best friends, who all explore many worlds to defeat the Heartless, and save the hearts of their worlds. However...that all changes when Xehanort and his new Organization return to complete a new goal: To control every single world, and rain chaos and despair upon them. But is that really what Xehanort is planning? Or does his plan involve something...more? The girl and her friends will met new friends, new enemies, travel to different places, and discover a new power deep within them all. And what fun is an adventure...without the Paopu trio? Will these heroes become supreme? Or will they give into the Darkness and die?

Everybody knows the story of Sora, Donald, and Goofy. They know about the shady group known only as Organization XIII, but nobody has heard Takeo's story. Takeo was a normal boy, living in Traverse Town. He usually kept to himself, as he didn't like being in big crowds all that often, and he kept his distance from most people, meaning he didn't have a lot of friends. But Takeo's life changed forever once he made the biggest discovery of his life. The discovery that he could wield a legendary Keyblade.
