1x57 - Pokémon Horizons: The Series

Liko and the others visit Clavel and Omodaka together with Friede, where they're given some information on Terapagos. However, it seems the two of them know nothing at all about the "Ancient Adventurer" or "Laqua". Instead, they introduce the group to Orange Academy's history teacher Raifort, who they think might know something.
