Returning to Artazon once more, Liko, Roy, and Dot meet up with Hassel, Brassius, and Alex as they prepare for an upcoming arts festival. Roy is eager to start his Tera Training aptitude test against Brassius, but the Gym Leader is too busy, so Roy battles Nemona instead. After Roy loses, Brassius tells him he’s not ready for his test, so the young Trainers work on art projects in the meantime. The process leads Roy to realize what he’d been overlooking in battle, and Brassius finally accepts his challenge. Will Roy and Fuecoco be able to successfully use Terastallization to pass the test?
