Our heroes are in Gardenia Town for May's next Pokémon Contest, and there are a few new faces to meet. Say hello to Mollie and Yuma: one's a beginning Coordinator, the other an experienced pro here as a spectator! Of course, Brock falls for Yuma on sight. And when she praises his skills as a Pokémon breeder and says that she takes on new Coordinators as students, he signs up for the Pokémon Contest in a flash. Now May has two competitors to look out for!

Even though it's their first time at a Contest, Brock and Bonsly do a great job in the appeals round. So great, in fact, that Yuma invites Brock to come study with her after the Contest is over! Brock defeats Mollie and then faces off against May in the final round, with his Marshtomp battling her Eevee. Eevee has learned a new move, Dig, but Marshtomp's can track Eevee's movements underground. Looks like May will have to come up with another strategy if she wants to win!

This match goes down to the wire, but after a hard-fought battle, May comes out the winner. That's no problem for Brock because Yuma said she'll take him on as a pupil whether he wins or loses. Except after the Contest, she tells him he's so good, he doesn't need her help. She's going to take Mollie as her pupil instead! Crushed, Brock gives up on the Contest world, but at least May has new hope for the future—and a new prize ribbon!
