What happens when you start your Pokémon journey with a rival? Do you feel happy that you have someone who can match you step for step? Or do you feel like your too far ahead to consider them a rival? Join Kana and Acelin on their Pokémon journey and read as they grow into fully capable trainers. But note how their relationship changes with them, from childhood friends to rivals...and maybe something more. But with each new change comes a new hardship. Will Kana and Acelin be able to stay with each other, or will one of them leave the other behind to become a hero...leaving the other to live in their shadow?
