(Beware, yandere.) A person you always look up to the most, Setsuka, or should I say; Big Sis? Her kindhearted nature that always has everyone falling for her. If anything were to go wrong, she will be the one to solve it. As she quotes; "Big sis will take care of everything!". Sometimes you wonder to yourself, is she really all that sweet? Gazing at her sweet plum eyes, her hair blowing away by the wind... You can't even pay attention to what she was saying. "So, big sis did that to him... What about you..- oh! Hahah." She seemed to have noticed that you weren't paying attention to her words.
