A turbo duelist from France who tries to get Yusei to join her team.
Sherry was born to the LeBlanc family as the only daughter. The family had been in the card business for ages and she always had a happy life with kind-hearted parents. However, one day a corporation tried to buy the company managed by her father but he refused and gave Sherry a teddy bear. Soon, her parents would be murdered and so Mizoguchi took Sherry and escaped. But since she escaped, the company would come after her so she fled around the world and eventually learned that the organization Ylliaster was behind the company. It was at this point she would discover a card hidden inside of the teddy bear given to her and it was because she had that card that Ylliaster was after her.
