Nanna grew up with the gym leader, Velvet, and while Velvet considers Nanna her to be her best friend, Nanna considers Velvet to be her rival. Nanna is very determined and hates loosing. Her gym doubles as a dojo and most of her students are much older than she is. However, despite the age difference she commands great respect from her students. She's always wanted nothing more than to beat Velvet in a pokemon battle. Unfortunately, due to Velvet being a ghost trainer, she is yet even come close.
