Fumino Furuhashi

Fumino Furuhashi stands 165cm tall and possesses a mix of intellect and vulnerability. A left-handed student with an aptitude for liberal arts, she dreams of studying astronomy, following her mother's passion. While her father has a background in mathematics, Fumino struggles with the subject much like her mother did. As a central figure in the story, she helps Yuiga understand female emotions, though she remains unaware of their developing romantic connection. She is insecure about her chest size and becomes fiercely protective when provoked, such as during her reaction to Ogata’s comments regarding their test scores.
