When the player and Cain first reach Agate City, they will find Aya and Hardy asleep in the middle of the streets. Shortly later, the player will encounter Terra and is brought to the circus by her.
In the circus backstage, the player will meet the other two circus leaders, Samson and Ciel. They suggest that the player should go and look for Hardy while Cain and them will look after Aya. Before leaving, Samson tells the player that although they are gym leaders, they won't accept battles unless the challenger has a battle pass.
After finding Hardy and obtaining the Battle Pass - Fury, the player can return to the circus and Samson will accept the battle. Defeat Samson and grant access to using HM Surf outside of battle.
Later on, after Cal reveals that Terra is part of Team Meteor, the player returns to the circus. When the player goes back to the circus backstage, Terra will then be cornered and escapes into a computer. The player is then forced to hunt her down and fight her in the Glitch World. After the player defeats her and leaves the glitch world, Samson turns off and restarts the computer she was in while she was inside. The current state of Terra still remains unknown.
Later on, after helping Titania in the Water Treatment Center, the player returns to the circus and Ciel will give the player the final battle pass. Defeat Ciel and grant access to using HM Fly outside of battle.
There are many move tutors that will teach your Pokemon moves in exchange for some shards.
