Age: 16-17 Birthday: May 6

A kind hearted orphaned high school student who, at the start of the story, begins living in a tent. She is then found by Shigure and Yuki, who offer to take her in in exchange for housekeeping. She loves to cook and describes herself as an excellent housekeeper. She also has an after-school job as a janitor to pay her tuition fees to avoid being a burden on her grandfather. She is depicted as polite, optimistic, extremely kind, and selfless; several other characters, including Kyou, Rin and Hanajima, tell her she needs to look out for her own interests and not shoulder everyone else's burdens.

Tooru habitually speaks formally (see Honorific speech in Japanese), but not always correctly, a habit she picked up from her father, Katsuya, after he died when she was three, as a way of replacing him in her mother's eyes. Tooru's mother, Kyouko, raised her alone until she died in a car accident shortly after Tooru entered high school, a few months before the start of the story. Tooru repeatedly calls Kyouko the most important person in her life and treasures her photograph; when she falls in love with Kyou she feels guilty of being "unfaithful" to her mother's memory.
