Saotome, or "Otome", was a classmate of Aki and Misao. She was also the then-girlfriend of Tohma before he abandoned her to die at the hands of a monster.

Since Saotome died early on in the game, not much is known about her personality. However, judging from the first conversation she was seen in, it can be assumed that Saotome was acting like the stereotypical girlfriend. She often would cry out in fright at certain things, such as Yoshino's accounts of the supernatural occurrences around school, and cling to Tohma in an effort to be comforted. The initial assessment of her personality seemed sweet and naive.

This would prove to be an act as Saotome took part in the bullying of her classmate, Misao, who was also in love with Tohma. Despite encouraging and helping them, Saotome continued to play innocent about her behavior until the game's events.
