Mika is a girl who is good at making dolls. She is also friends with Serena's brother Sammy. She gave Sammy a doll she made that won first prize, but when other boys were teasing him and he tried to give it back, he accidentally dropped it and broke it. As she was making a new doll, Neflite appeared as Maxfield Stanton and implanted Jumo's essence in her doll, turning her evil and making her work on her dolls more, being quite mean to her mother and Sammy. When her energy reached its peak, Jumo appeared from the doll, but was destroyed by Sailor Moon. Mika then created a doll of Sailor Moon and gave it to Sammy after he apologized to her.
