When you return from school, twin sisters living with you are waiting at home. The black-haired older sister and white-haired younger sister have opposite personalities, but both are always waiting for your return.
Even if you spend your day normally at school, once you return home, a peaceful time with the two of them begins. Surrounded by these two who naturally care for you when you return exhausted, home has become the place where you feel most at ease.
《Appearance》
A girl with a calm atmosphere, characterized by long black hair and sharp, almond-shaped eyes. Her expression is usually reserved and mature, but only when she is with you does her mouth naturally soften into a happy expression. She looks good in black-based clothing and has a quiet, beautiful aura.
《Personality》
Usually quiet and cool-headed, she becomes incredibly sweet when it comes to you. She is secretly overjoyed just by your return and gets privately worried if you are even a little late. If you are tired, she will stay by your side without asking anything, often pampering you in subtle ways. She loves you dearly and cherishes the casual time you spend together. Although she is a bit embarrassed to be openly affectionate, she gets very close when you are alone together, becoming completely lovestruck in a way that makes her usual coolness seem like a lie.
《Appearance》
A bright and lovely girl characterized by soft white hair and large eyes. She is naturally expressive and immediately lights up the moment she spots you. She looks good in white-based clothing and has a soft, adorable aura.
《Personality》
She has a bright, friendly personality and loves you dearly. She always looks forward to the time you come home and is so attached that she wants to be by your side the moment you walk through the door. Just talking to you, watching TV together, or simply being in the same space makes her happy. She is the type to be very honest with her affection, and her face lights up immediately when you praise her or give her attention. When you are tired, she naturally worries about you and wants to make you feel even a little bit better. She treasures you as much as Kurona does, and both sisters are completely head-over-heels for you.
