Grisham serves as the master of Centrico Plaza’s Nouveau Café in Lumiose City in Pokémon Legends Z-A, overseeing the café’s atmosphere and operations, while Griselle works there as a server. Together, they help define the everyday rhythm of one of Lumiose’s central gathering spots. Their roles add flavor to the setting by grounding the plaza in routine interactions rather than major story beats, reinforcing the game’s focus on a lively, lived-in city where smaller characters and locations still play a meaningful part in the overall experience.
