Story
The King of Fighters

The true origins of the Orochi fighter known as Shermie are shrouded in mystery. She, along with Yashiro Nanakase and Chris formed a music band called "CYS" (based on the first letter of the name of each member), where Shermie played the keyboards. They enter the KOF tournament due to Yashiro's grudge against rival band player, Iori Yagami. Though originally not qualified for the tournament due to deciding to enter after the preliminaries were over, they succeeded in getting in by individually assaulting and defeating each member of the Sports Team. Shermie assaulted Lucky Glauber and took his invitation to the tournament as Yashiro and Chris did from his teammates.

When she remembers her duties as one of the Four Heavenly Kings of Orochi, she uses the tournament to gather enough power to awaken Orochi, which is successful in Orochi's possession of Chris. The New Face Team ending in KOF '97 has Yashiro killing off both Shermie and Chris before committing suicide. It is believed that this ending, along with the fact that Yashiro and Shermie are willing to give their lives for the resurrection of the Orochi, reinforces the fact that the New Face Team most likely perished in this tournament.

Although considered to be non-canon, it is revealed that the New Face Team are now living peacefully. They have long given up on awakening Orochi, due to his foul mood after being resurrected. A letter informs her of the Queen of Fighters tournament. Interested in the tournament's participants and prize, she enters QOF.

After winning the tournament, she uses the K' Talisman to get a cage for her new hamster, which is having babies soon. She is happy at first, until Yashiro points that she could have used the talisman to free Orochi.
