Awayuki Mizumi

A second-year Saika Girls' Academy student, Mizumi also serves as a waitress at the 'Shikisai Home' Inn, where she works with her twin sister, Sakiha.
She embodies the role of a comforting presence, characterized by her unwavering dedication and kindness.
Despite Mizumi's nurturing nature, she carries an air of fragility due to her poor health.

Her commitment to her duties at the inn is so intense that she often exhausts herself to the point of collapse. This very vulnerability occasionally leads Sora to see her in light of his late sister.

"Pardon the intrusion while you're relaxing; I've brought dinner."
"It's the first time a man has... treated me this way."
"Kazami-sensei, if I were to describe you in terms of family, you'd be like an older brother."
