Saori Otokawa is a student residing in the St. Arcadia Academy dormitory alongside protagonist Takurō Hayami, whom she is the first to meet upon his arrival. She willingly performs dormitory household chores. Her background includes participation in the school's Biblical Studies group in the original game, while the anime adaptation places her in the Paranormal Research Club instead. Fundamentally kind, Saori also possesses a strong will when required. She harbors unexpressed feelings for Takurō and, unlike other female students at the academy, does not seek to exploit his "ultimate sex power." This genuine affection and protectiveness make her a recurring target for schemes orchestrated by Leona Morimoto, who controls much of the school through family influence. Physically, Saori has long blue hair reaching her waist and green eyes, typically seen in the school uniform and a hairbow. Her hobbies include reading, and her special talent is cooking. Her core traits remain consistent across official media adaptations.
