Miyuki Sakuragi, wife of Sakuragi family head Kazuhiko and mother to Yaeka Sakuragi, supported herself and her younger sister Kanami Kurosaki after their parents' death. During her student years, she worked part-time at Inoue flower shop, enjoying being constantly surrounded by flowers. She first met Kazuhiko when she accidentally collided with him there, hitting him in the face with a potted plant's branches. The shop owner introduced Kazuhiko as a regular customer who practiced ikebana. Learning of his hobby resonated with Miyuki, as her own mother had practiced ikebana, though Miyuki had given it up due to frustration. Kazuhiko encouraged her, emphasizing enjoyment over perfection.
Their shared interest led to further meetings. Miyuki asked Kazuhiko to teach her ikebana, exchanging contact information. She viewed their initial outings as lessons, though she found him "wunderschön" despite his formal speech and described him as considerate. She invited him to Café Fuyutsuki, where conversations deepened. During one meeting, Miyuki revealed her resilience after her parents' death, explaining her focus shifted to supporting Kanami rather than dwelling on grief. This maturity and dedication impressed Kazuhiko.
After marrying, Miyuki became central to the Sakuragi household. She acted as a mother figure to young Tōru Kirishima after he joined the family, providing emotional stability. She later gave birth to Yaeka, who strongly resembles her physically.
Years before the main story, Miyuki suffered a severe traffic accident, leaving her comatose and hospitalized. The accident occurred when Yaeka was too young to remember her, contributing to Yaeka's initial emotional distance. Before losing consciousness, Miyuki explicitly entrusted Kirishima with the care of both Yaeka and Kazuhiko. Her absence profoundly impacts her family, particularly Yaeka, who longs for her mother’s warmth.
Flashbacks depict Miyuki as gentle, calm, hardworking, and occasionally clumsy. Her relationship with Kazuhiko blossomed through their mutual appreciation for flowers, contrasting his role. Her resilience and dedication to Kanami shaped Kanami’s attentive care for Yaeka after Miyuki’s hospitalization.
Miyuki's coma creates an enduring impact. Her past kindness and role as a moral anchor, especially for Kirishima and Kazuhiko, are frequently remembered. Her physical resemblance is evident in Yaeka, while Kazuhiko and Yaeka share similar expressions originally noted between Kazuhiko and Miyuki. Her legacy continues through Kanami, who embodies Miyuki’s nurturing qualities as Yaeka’s guardian. Family members and associates often reminisce about Miyuki, reinforcing her ongoing influence.
