Rei

Rei is a teenage boy with short, tousled slate-gray hair and matching gray eyes. He wears the official Galaxy Team Survey Corps uniform, featuring a dark blue tunic with white and red accents, paired with a vibrant red scarf and a matching red headscarf bearing a Poké Ball insignia. His outfit is completed by white pants, protective gaiters, and traditional straw sandals.

Diligent, earnest, reserved, adventurous, and helpful.

Survey Corps member of the Galaxy Expedition Team

Originally a resident of the modern Pokémon world, Rei was transported back in time to the ancient Hisui region by the legendary Pokémon Arceus. Tasked with seeking out all Pokémon, he joins the Galaxy Expedition Team to assist Professor Laventon in compiling the land's first-ever Pokédex. As he explores the wilderness, he works to bridge the gap between humans and Pokémon while investigating mysterious space-time distortions.
