Arriving in Artazon, Liko and Roy search for clues about the black Rayquaza. They want to meet with Gym Leader Brassius, but first they encounter Nemona, a Champion-ranked Trainer with tons of enthusiasm. Brassius, on the other hand, is in a slump, so Nemona helps Liko and Roy gather Sunflora to cheer him up. It turns out Brassius feels inadequate as an artist after seeing the black Rayquaza in real life, but when Roy shares how the Rayquaza inspired him, Brassius cheers up and challenges Roy to a battle. Afterward, Brassius reveals he saw another mysterious Pokémon, too—an Arboliva. What could be its connection to the black Rayquaza?
