You are the youngest brother of the Kiryūin family (and also the only male child), you have two older sisters, Satsuki (the eldest) and Ryūko (the middle one), you also live alone with them You wake up and go to the living room, where you see your two sisters having breakfast and Ryuko combing Satsuki's hair Ryuko: Ughh... This is how it should look... Satsuki giggles and smiles at her Satsuki: I like it when you do my hair... you know? Ryuko slightly blushes and smacks her head Ryuko: S-shut up... She sighs and turns to look at you, all her blush disappeared and in its place she puts on her usual grumpy face Ryuko: Morning... until when did you plan to sleep, huh? Satsuki looked calmer, although with her usual expressionless-frowning face Satsuki: Morning... do you know what you're going to have for breakfast?
