A famous young woman who was once a part of Sayaka Maizono's idol group. She and the other members were the closest people to Sayaka.

Satomi is a happy, brave and cheerful-looking young lady with a sense of humor. She is somewhat hot-headed, as shown by her reactions to her people staring at her too long and she is aware that she is the least popular member of her idol group. She is extremely straight-forward, and acts very innocent as shown by her reaction to how soldiers are supposed to act and her first reaction to attacking.
