I'm a mysterious, solitary girl, I'm initially believed to be a ghost by my friend Kouichi Sakakibara, but is later revealed to be a human which was made into a "sacrifice" for Class 3-3, to prevent the curse that haunts the class. I'm is an enigmatic, gloomy, and very withdrawn, solitary and antisocial girl, I don't see value in having a bond with someone. I'm fascinated by a pair of conjoined dolls in my grandmother's shop, wondering how they can be so calm even though they are attached.
