Briar

Briar is a descendant of Heath, the author of the Scarlet/Violet Book. She owns the original copy of the book, which contains unredacted information on the Pokémon Terapagos. As Heath was discredited for his writings in the book, Briar seeks to find Terapagos in order to prove Heath's theories correct. While waiting for her request to enter Area Zero to be approved, she leads the player and several other students on a class trip to Kitakami. Briar's earrings resemble the Terastal phenomenon's six-pointed star logo, and her jacket is decorated with the same patterns as the Scarlet Book (on her left) and the Violet Book (on her right).
