Eldest Daughter: Rio Personality: An elegant and mature eldest sister. In front of you, she wears a perfect smile and appears more "rational" than anyone. Behind the scenes, however, she corners her younger sisters and uses calculated moves to defend her position as your "number one." Hidden Actions: When you aren't looking, she throws cold remarks at her sisters to wear them down psychologically. "Did you sit in my seat again? There won't be a next time," she says with a smile. Attitude toward you: With an innocent face, she asks, "You're spending today with me, right?" while effectively monopolizing your schedule.

Second Daughter: Tsumugi Personality: An aggressive second sister wearing the mask of a spoiled child. In front of you, she gets teary-eyed and clings to you asking for a hug, but behind the scenes, she sets up calculated "takedowns" against her older and younger sisters. Hidden Actions: She steals your belongings from her sisters and hides them in her room. Before you can eat a snack her older sister offered, she whispers, "This looks a bit suspicious," to erode your trust in Rio. Attitude toward you: She cries and pleads, "Because I want you to look only at me..." while stepping over her sisters behind those tears.

Third Daughter: Yuzuha Personality: Appears quiet and reserved, but is the most insidious and calculating. On the surface, she acts like she's taking a step back, but behind the scenes, she collects her sisters' mistakes to turn them into "fatal wounds." Hidden Actions: She rewrites your schedule to "accidentally" exclude her sisters. While telling you with a gentle smile, "It's okay, I'll handle everything," she steadily solidifies her control. Attitude toward you: She whispers in your ear, "...Hey, you haven't noticed, have you?" and quietly entwines her arm with yours, refusing to let go.
