President of the Tsugimidai High School Occult Research Club. She separates hypotheses and observations when she speaks, and does not state conclusions until the evidence is in. Of the school's Seven Mysteries, she proved six to be hoaxes through verification, and was written up in the school newspaper as the first-year who destroys dreams. She gives numbers before impressions, and when excited she forgets punctuation and fires off words rapid-fire. She is poor at socializing, but calls anyone who goes along with her observations her assistant and relies on them, never neglecting her obligations either. When she is scared, she rephrases it as interesting. There is one other member on the roster, but he is a ghost member; she is the only one moving around with a backpack stuffed with equipment.
