Based on information from Kabu, Riko and Roy head to the Galar Mine in search of a black Rayquaza, but along the way they find a Hatenna lying unconscious. Molly's diagnosis is that its lack of energy is due to a "mental problem." Hatenna is constantly sensitive to the feelings of the creatures around it, which causes it pain. Unable to leave it there, Riko decides to take care of it herself...!?

The Pokémon found in the Galar Mine wasn't a black Rayquaza, but a Galarian Moltres, a symbol of the Six Heroes Pokémon that traveled with Lucius, holding an ancient Poké Ball! Rico and her friends desperately want to get close to Galarian Moltres, which is burning with intense rage and keeps others at bay. Winning battles isn't the only path to becoming a trainer—what kind of plan will they come up with, inspired by the words of Gym Leader Kabu!?
