The best friend of Yakumo Tsukamoto, Sarah stands out with her blonde hair styled in a bun. Raised in an orphanage in Britain, she is relatively new to Japan. Frequently seen with Yakumo, they are both classmates and members of the Tea Club. With her cheerful and positive demeanor, Sarah supports Yakumo, especially in navigating her relationship with Kenji Harima and dealing with unwanted attention from Haruki Hanai. She stayed over with Yakumo to keep her company while Tenma was away on the Kyoto trip.
Sarah holds several part-time jobs outside of school. She works as a nun at a local church, where she hears confessions, plays the organ, and looks after children. Despite her position as a nun potentially limiting her romantic prospects, she hinted to Akira Takano that she might have someone in mind. Additionally, at least one hopeful student has shown interest in her. Apart from her duties as a nun, Sarah also works at a Chinese restaurant with Hiroyoshi Asō from class 2-C, where she waits tables and cooks.
