Noa was at Dawn's house when Dawn returned home to Twinleaf Town with Ash and Brock for the Twinleaf Town Festival. Brock like all the girls he meets on his travels, instantly began flirting with her, but her overprotective Bellossom and his Croagunk quickly put a stop to that.
Noa is a Pokémon Coordinator that is studying with Dawn's mother Johanna to become better.
