Ash can’t contain his excitement as he arrives on Ula’ula Island for his next grand trial. But Nanu, the island kahuna, has other ideas and leads Ash to believe someone else is the kahuna. To Nanu’s dismay, Acerola blows his cover and convinces him to grant Ash a “pre-trial” battle. Nanu is convinced Ash isn’t ready, and after his Krookodile soundly defeats Ash’s Lycanroc, he seems to prove his point. But Ash never gives up, and he vows to stay on the island and train hard for a rematch!
