Plot

In the observation deck of the Brave Olivine, Liko and Roy are trying to get Uruto to clean the room since it's a shared space, but Uruto doesn't see the problem. Roy ends up exploding at Uruto, telling him to leave if he doesn't clean up properly. Rather than clean his room, Uruto leaves the airship, thoroughly annoyed with Roy. Meanwhile, in Manpūku Town, a boy named Rayu is trying to sell some paintings while watching his Grafaiai make one. Unable to sell any, Rayu leaves his place and passes by some Trainers talking about Strong Spheres, making Rayu interested in one to help his Pokémon. At that time, a hungry Uruto arrives in Manpūku and spots some Nanab Berry trees. He tries to pluck one berry but is stopped by Rayu, who claims the tree is his, leading to the two arguing until the trees' true owner comes out and his Mabosstiff chases the two boys. The two are able to get away from the Boss Pokémon and rest for a while. When Rayu gets up to leave, he and Uruto see their Pokémon getting along very well, making Rayu much more willing to be friends with Uruto to the point of sharing his food with the hungry boy. It turns out because of Grafaiai's picky nature, it's difficult for Grafaiai to interact with anything new, hence why seeing Grafaiai getting along with Sableye made Rayu really happy. Uruto notes the close bond Rayu has with Grafaiai, and he doesn't deny it. Upon seeing Grafaiai trying to eat Sableye's gems, Uruto suggests having Grafaiai eat something that Sableye can also eat, resulting in the Toxic Monkey Pokémon successfully eating an Oran Berry for the first time. After plucking more berries, Rayu brings Uruto to his place and they begin talking. Uruto brings out his Dusk Ball, telling Rayu there's an amazing Pokémon that hasn't acknowledged him yet. The two boys then talk about Rayu's desire to help Grafaiai become a better artist, and Rayu almost asks Uruto something but backs out at the last second.

The next morning, Roy finds Uruto gone. Liko and Dot come to find out what's going on, and the latter notes the random rocks laying around. Roy initially agrees, but realizes the rocks are simply memories of the journey Uruto had been on and that he acted wrong when talking with Uruto the day before. Wanting to apologize to Uruto, Roy leaves to find him despite having no leads to do so. Meanwhile, Uruto wakes up to find not only Rayu gone but also his Dusk Ball. Seeing the blue saliva left on his bag, Uruto tracks down Rayu with the saliva that Grafaiai left behind. In Manpūku Town, a store owner is in the middle of completing a transaction when Rayu arrives with the Dusk Ball he stole from Uruto, hoping to trade it for a Strong Sphere. Indy and Rubella hear the exchange and agrees to the trade just as Uruto comes demanding for his Poké Ball back. Upon seeing Uruto, Rubella stows away the Dusk Ball in her pocket, Uruto then engages the two Explorers in a battle, with the latter using the Strong Spheres on both their Darmanitan. Despite landing the first hit, Sableye is quickly overwhelmed by their strength. Grafaiai steps up to help its friend by dealing damage with Sludge Bomb, but a Fire Punch from Rubella's Darmanitan sends it flying. Rayu tearfully apologizes to everyone for causing this mess as he holds his weakened partner. Uruto Mega Evolves Sableye into Mega Sableye while Rayu watches the two Darmanitan attack fearfully. He even tells Uruto to abandon him for his mistakes when he sees Mega Sableye struggling, but he refuses to, saying that there's no reason to fight for someone's sake. Unseen to the others, Uruto's Dusk Ball begins shaking in Rubella's pocket. Uruto has Sableye press on, but when it is nearly defeated, the Dusk Ball opens to save Mega Sableye, revealing a Dragonite in the process. Dragonite is able to take on and defeat the two Laquium-enhanced opponents singlehandedly, forcing the Explorers to retreat. Uruto chases after the truck that the two Explorers are in as Rayu thanks him.

Afterwards, Roy arrives in Manpūku Town, having just missed Uruto. He asks Rayu, who is suspicious of Roy. Upon hearing his intention with his friend, Rayu tells Roy where Uruto went and finds Roy to be a good person too when he compliments the painting on his back. At their usual place, Rayu happily watches Grafaiai paint with a new color.
