Tsuki Uzaki is the 43-year-old mother of Hana, Kiri, and Yanagi, and wife to Fujio Uzaki, turning 44 by Chapter 51 with a November 2nd birthday. All her children resemble her physically, not their father. She possesses fair skin, silver hair typically styled in a side ponytail over her right shoulder, and predominantly squinted blue eyes that open wide when surprised. Despite her age, she maintains a deceptively youthful appearance and is below average height. Her figure is notably curvaceous, sharing comparable bust measurements with her daughter Hana. She frequently wears a white long-sleeved shirt layered over a black sleeveless undershirt, a yellow buttoned skirt, and white flats. Outwardly gentle and reserved, Tsuki presents a contrast to Hana's energetic personality. She forms an immediate, lasting impression of Shinichi Sakurai as "scary" due to his intense gaze, though her view of him shifts over time. Deeply overprotective of her children, she reacts with visible distress to situations like Hana staying at Sakurai's residence. Internally, she often engages in harsh or cynical thoughts about others while striving to be a caring mother. A defining trait is her tendency toward misinterpretation, frequently imagining elaborate sexual or inappropriate scenarios involving Sakurai and Hana, fueled by her active imagination. These misunderstandings include believing Sakurai prefers mature women and targets her, or that he shares an unconventional relationship with Hana. Her habit of watching soap operas and melodramas likely contributes to these exaggerated perceptions. Within her family, she balances maternal duties with managing frequent misunderstandings. Her protective instincts extend to all her children, including Yanagi. She assists Hana in learning to cook to woo Sakurai and later helps Sakurai improve his own cooking skills.
