She is married to a man named Tooru (whom she only chose for his looks) and makes sure to always come home on time. She loves taking selfies and cosplaying, and she constantly craves for approval and Likes. She also loves posting sexual videos on "Dickdog" (ディックドッグ) which have become a hot topic among students.
