Takayanagi Sayuri

The mother of Kana, the main heroine and the protagonist's girlfriend. Her husband is currently on a five-year long-term assignment overseas, leaving the house empty. She is now a full-time homemaker, living at home with her daughter.

She met the protagonist through her daughter. From their first meeting, she had a favorable impression of him due to his clean appearance, polite speech, and shared love of physical activity and exercise.

She has a dependable and caring personality, seen by others as a reliable woman. She has a wide social circle and many friends. Her daughter Kana adores her, and their mother-daughter relationship is excellent.

She chats easily with male acquaintances but has strong moral standards regarding fidelity. She has never once been intimate with any man other than her husband.

However, her strong maternal instincts lead her to sympathize with the protagonist, who lives apart from his parents, causing her to tend to be overly lenient with him.

Her hobby is physical activity (sports). She jogs every morning and visits the nearby public pool twice a week.

She enjoys sports in general, but swimming is her particular passion and strength. During her student days, she belonged to the swimming club and was a regular top finisher at regional competitions.

Having continued exercising even after giving birth to her daughter Kana, her body remains more supple than her age would suggest. She often looks about ten years younger than her actual age, and her daughter is frequently mistaken for her sister.

She possesses an outstanding figure with large breasts, a tight waist, and a full butt, but she's starting to worry about the excess fat around her stomach that's begun to sag with age and her breasts, which feel more droopy than they used to.

She's too old to be considered in her prime, but her sex drive is quite strong. Three years have passed since her husband was transferred, and she spends her days feeling somewhat frustrated with her pent-up sexual desire.
