Yuzuki Shiba Her classmates call her "Yuzuki-san" or "Yuzu." A reliable older sister with a leader-like personality. She is smart and trusted by those around her, but she can be airheaded in strange ways and has mysterious obsessions. She works part-time at the same cafe as Kentaro. Refer to character sheet.

Azusa Shiba Her classmates call her "Azu-chan" or "Azu." A cheerful and bright middle schooler who is actually a bit shy. Since she is the student council president, she is serious at school, but at home, she acts selfishly toward Kentaro and pampers herself with Yuzuki and Miho. Refer to character sheet.

Miho Shiba At her company, she is called "Miho-san" or "Sales Manager Shiba." The energetic pillar of the Shiba family. As a high-powered career woman and sales manager, she travels often for work, so she showers the three of them with affection whenever she returns home.
