Thunder must wrangle and lead the Hero Dragons in a desperate attempt to save Tom and the riders from a dangerous new dragon, The Glass Caster.

When Jun does a Tarot reading for the team, she interprets its meaning to be that the riders will disband! In an effort to defy this fate, Jun forces the group to stick together as they search for a dragon that has breached the Rakke Town eel barrier.
