Reiko showed up in "The Purr-fect Hero" as a character of the day. She's basically a sweet person, though the kids at her school sometimes find her a bit strict. She'd made a promise to let the children see some Pokémon for Kids Day, but the three trainers she'd lined up bailed on her. That's when Ash and his friends stepped in and offered to show off their own Pokémon instead, saving the day.
