Saori Shikikagami

She is the older sibling of the Shikikagami sisters but unlike her younger sister, she is an upper-ed student at the academy, having paid the required fees before their family fell on hard times. She has a habit of taking her clothes off without minding where she is, who sees her as she undresses or if it is appropriate or not. She also appears to be as ditzy as her younger sister although unlike her, she merely tends to strip her clothes off. Font: LVSB Wikia.
