Kayako Yuzuki

Kayako Yuzuki (夕月 香也子 Yuzuki Kayako) is a young woman who works for City Hall. She is also the (possibly twin) sister of Kayoko Yuzuki and a childhood friend of the protagonist, Yūya Kisaragi.

Appearance
She has red glasses, green hair and green eyes. Unlike her sister, she wears more casual clothing like a sweater and a skirt.

Personality
She's kind and patient, but has a mischievous and childish side to her that is showcased on her 'date' with Yūya and her bickering with him about it days following. She often tries, and fails miserably at, being mature.

​Background
She was an old childhood friend of Yūya from when they were younger, but they lost contact. Kayako later meets him again, to help with Izaemon, as a community representative.

Yūya Kisaragi
Like Kanna, Sayuri, and Haruka, Kayako knew Yuya when they were kids. She calls him by a nickname, Yu-bou, and often offers to help with his “girl troubles”. It's unclear if she officially likes Yuya or was just riling him up, but she kissed him at the end of their date.

Unlike with her, Yūya’s feelings about Kayako are made clear. He thinks of her as a big sister figure but gets very irritated by her shenanigans, calling her “suffocating”.

​Kayoko Yuzuki
Kayako has a pretty standard relationship with her sister.
