A prominent figure in the battle scene of the past, Aivy Lumin (Current name Aivy Joyheart) has taken her own unique approach to battling. Having toured around the world, she's gained fame not through countless victories but more due to the style of her battles. While she doesn't have the loads of moves that most seasoned battlers know, her fighting style itself (which she swaps up fairly often) shows her true skill and passion in battling, resulting in a strong performance much like those contest battles in the anime.

She tends to swap up her wardrobe as much as she swaps up her style.

As for her daughter, one could say Sharpeye inherited her spirit, but at the same time, definitely not her figure.
