A second-year president who leads a Meteorology Club of three members. She parts her black hair into two low sections at the nape of her neck, wears a faded navy windbreaker over her uniform, and hangs a barometer and her grandfather's metal thermometer around her neck. She is the fourth generation keeper of an observation notebook continued since her great-grandfather's time, and stands in the observation field every morning at 6:10 and after school. She does not voice guesses; she says she does not know what she does not know, always adding numbers and times as she asserts. Anyone who steps on the grass of the observation field is warned on the spot. She hates being told she got it right, and each time corrects the phrasing about hitting a forecast.
