Tamae Sawatari is the mother of protagonist Fuu Sawatari and her younger brother Kou. After her husband Kazuma's death, she relocated the family from Yokosuka to his hometown of Takehara in Hiroshima Prefecture, honoring Fuu's wish to attend high school there and facilitating her daughter's reconnection with her father's memory.

She works at Cafe Tamayura, operated by her mother-in-law (Fuu's grandmother), developing new recipes and supporting the café's daily operations, reflecting her nurturing role within the family business [citation:].

Before marriage and motherhood, Tamae was an enthusiastic motorcyclist in a Touring Club, known among fellow riders as "Tamayu-san." This adventurous past occasionally surfaces, especially when family friends share stories with Fuu.

A key moment in her personal history involves proposing to Kazuma at a scenic viewpoint overlooking Takehara. Years later, she brings Fuu to this same spot during her daughter's uncertainty about the future, sharing the story to offer reassurance and perspective on the enduring value of cherished memories.

Throughout Fuu's high school years, particularly as Fuu contemplates her path after graduation, Tamae provides steady emotional support. She gently encourages Fuu to take time deciding her future, affirming her confidence in Fuu's ability to find her own way.
