For Livvi Weston, her goal of surpassing her older sister has led her to part ways with her old friends and set off to the Johto region by herself. But the path to success doesn't always have to be walked alone. Livvi is joined by Alicia Law, a rookie trainer with a mysterious past, who places herself in her care as they both aim to earn gym badges to compete in the Johto League.

To the south-west of Kanto and Johto lies the Hoenn region. For pokémon trainer James Burton, it's a place that offers fresh challenges and opportunities. Alongside him are his old friend, Richard Winter, his younger brother, Will, and a new resident of Hoenn, Nicola Hewitt, all with their own goals in mind. Ahead of them lies the long and difficult path to the Hoenn League.
