Among the five, she is the calm, dependable big-sister figure. However, she is so serious that she tends to overthink things once they catch her interest. Her family home is old-fashioned and still uses a rotary phone. Perhaps due to her upbringing, she is often out of touch with the modern world. Combined with her serious nature, this leads to a ditzy side where she occasionally does eccentric things without worrying about how others see her. She isn't stupid, but rather the "going my way" type. She seems to like the word "Path" (or "Way") and preaches about the "Path of Humanity" at every opportunity. She sometimes quotes historical figures, such as "There is no path before me; the path is created behind me." She has no tolerance for alcohol and gets drunk easily (without realizing it). She currently works as a Japanese language teacher at a middle school.
