Choose your fate. Eight stories await.

Step into the shoes and live the stories of each of the eight travelers and freely explore the world of Orsterra. Then, carry your choices and adventure into the main game with save data transfer.
Use each character’s special abilities in and out of battle. Break through enemy defenses by discovering and targeting weaknesses.
