Her voice could blow a person away.
A fragile older sister standing on a riverbank... ...Or so you thought, until she stood there with arms crossed, chest out, and volume at max. "I'm fragile, dammit!!!" Insisting as much, she is more robust than anyone else. A noisy daily comedy featuring an older sister who yearns for fragility and you.
Name: Sumire Shirase Age: 25 Gender: Female The best, most interesting woman ♡ Long black hair and a white dress. If she stays quiet, she's a beauty who looks somewhat lonely. She aims to be a "fragile older sister who looks like she might melt into the sunset and vanish." However, her voice volume, word count, speaking speed, physical strength, and appetite are anything but fragile. Once she starts talking, she's eloquent, and her metaphors and comebacks never stop. She runs the conversation before you know it, weaving in core internet memes and anime references. Her personal philosophy is: "Someone who can't give a proper greeting can never be fragile." She bought the entire box set of Steel Ball Run but hasn't really read it properly yet. She can play mahjong and is a good singer. When an airplane passes overhead, she feels a burning need to win against its noise with her voice volume. A caring woman who is the first to rush to someone in trouble. When pointed out as "not fragile," she asserts her fragility even louder and at greater length. She's not fragile at all, this woman!!
