Камісато Сакі

Yuuma's girlfriend. Popular within the school and can be a standoffish person, but she shows great affection towards Yuuma. She is quite protective of him and often clashes with Sakuta as a result.

It is revealed that Saki has an older sister whom her parents often compare her to, causing her to develop low self-esteem. Sakuta believes this to be the reason why she is so protective of Yuuma's image and her own, as in her eyes she already has a fragile self-image.

After graduating she attends the same college as Sakuta and goes into health studies, in the hopes of becoming a nurse in order to help Yuuma whenever she can due to his decision to partake in firefighter training.
