Our heroes’ Alola region education continues when they learn about the sleeping habits of the Pokémon School’s resident Komala and take a trip to Mt. Lanakila to see where Snowy’s Egg was found. School life is soon interrupted when they are called to action as the Ultra Guardians, sworn to protect the people of Alola and help guide lost Ultra Beasts! What will their first mission have in store? Meanwhile, Team Rocket encounters someone from Mareanie’s past, and a cunning Alolan Meowth threatens to upset the balance of this bad bunch. Finally, Ash and Litten take on a superstar of Alola’s Battle Royal, a popular Pokémon School graduate returns to Alola, and a brand-new friend appears from beyond the Ultra Wormhole!
