Pokemon the Series: Sun & Moon

Satoshi and Pikachu arrive on Melemele Island in the Alola region after his mother wins a trip there. They become lost while chasing a Pokémon, and eventually stumble upon the Pokémon School, where students learn about Pokémon. At the school, Satoshi encounters Team Skull and witnesses the power of Z-Moves, which require trainers and Pokémon to be in sync. He later receives a Z-Ring from Kapu Kokeko, the guardian deity Pokémon of Melemele Island.
