The Professors' New Adventure! - S21.E12

Following their journey through the Ultra Wormhole, our heroes return to the Pokémon School, where Lillie thanks everyone for their help saving her mother. Later, during a walk on the beach, Professor Kukui asks Professor Burnet to marry him! They aren’t planning a wedding ceremony, but our heroes have other ideas...a surprise ceremony awaits!

Then, Lusamine asks the Pokémon School class to join the Ultra Guardians—a group that protects Alola from Ultra Beasts. And just after the bouquet toss, Solgaleo appears! Ash gets his wish and thanks the Legendary Pokémon for all its help, and he looks forward to seeing it again someday.
