Sherry is a turbo duelist from a rival team, hoping to recruit Yusei to her team. She belonged to a rich family until her parents were killed by Yliaster when she was young, and she is now under the care of her butler, Elsworth. She enters the WRGP to get closer to Yliaster and find out more about her parents' death. However, during a mission with Yusei and Bruno, she becomes separated from them in a wormhole and ends up in an alternate dimension where she meets Zone. Although she is mainly focused on Yusei, she also takes an interest in Akiza after being saved by her powers. She uses a Fleur Knight deck, her key monster being Fleur de Chevalier.
