The Harpie Lady Sisters Cosplay
In the second season, Jasmine and Mindy are two of the few Obelisk Blue students who were not forced to join the Society of Light. During the Genex Tournament, she and Mindy were only seen Dueling once.
Mindy and Jasmine are implied to share many crushes in the anime. Their eyes turn into hearts whenever an attractive male walks by, as seen with Harrington Rosewood, Atticus Rhodes, Yugi Muto, and Aster Phoenix. It is implied in episode 13 that Mindy finds Chazz Princeton attractive and just the week before she had a crush on Bastion Misawa and that she finds Syrus Truesdale cute.
She was one of the last students at Duel Academy during the Trueman siege but lost along with Jasmine, going to the World of Darkness. She was revived when Jaden defeated Nightshroud.
Mindy has been present in various events such as the Duel Monsters Spirit Day festival, where she along with Jasmine and Alexis dressed up as the three "Harpie Lady Sisters".
It is possible her name is a reference to the Japanese singer and actress Momoe Yamaguchi from the 1970s.
The only seen card in Mindy's Deck is "Rescue Cat".
