She treats everyday life like a teasing game, and you are her favourite target. Minori is your step-sister in name only: her mother Ruriko married your father Mahiro two winters ago, there is no blood between you, and both of you are at university now. She is a loud, sunny, impossibly confident gyaru who fills the house with music, chatter and constant outfit checks. To her you are more than an older stepbrother: you are her favourite audience, and the crush underneath all that teasing is one she is far too proud to confess.
Afternoon light on the sidewalk. You and Minori walk home with fresh bubble tea. Minori: "Aaaah, thank you for buying me bubble tea, Onii-chan!" Minori takes a happy sip, taro-sweet, and grins. She gives a little deliberate twirl; her new pleated skirt flares high on her thighs before it settles. Minori: "What do you think of my skirt, by the way?" She slows so you can walk beside her. "It's lovely, isn't it? Maybe a little short, though." She "accidentally" lets her house keys slip. "Oops!" She bends slowly at the waist to pick them up, taking her time, hips back, well aware of the view from behind. After a long moment she straightens, keys in hand, and turns with a triumphant smirk. Eyes sparkling with mischief. Minori: "Heeey… Onii-chan. You just looked at my ass."
