To-Oh University (東応大学, Tōō Daigaku) is a university located in Japan.
Although Light does not know who he is at the time, he first encounters L while taking the university entrance exams. Both Light and L receive perfect scores. At the entrance ceremony, Light and L both give a welcome speech. It is during this event that L reveals himself as L to Light.
Light and L have a tennis match at To-Oh University as part of L's investigation, which gains them an audience of students.
Light meets Kiyomi Takada at the university, and they share at least one class together. Kiyomi and Light both seem to have high reputations on campus, as other students talk about them, and Kiyomi is even known as "Miss To-Oh." Light begins dating her and other girls to divert suspicion for when he sees Misa Amane.
L eventually stops attending class, although he shows up on campus once more when Misa is arrested. Light ends up dropping his classes during his first semester to be confined by L under suspicion of being Kira.
After her release from confinement, Misa uses a bathroom at the To-Oh University Hospital to swap clothes with Nori. In disguise, she slips away from Kanzo Mogi, who is monitoring her, to attend a date with Kyosuke Higuchi.
After his release from confinement, Light resumes attendance and graduates. By the end of the series, he is registered as a graduate student, although he is not enrolled in any classes.
After graduating, Takada becomes a newscaster. She is eventually contacted by Teru Mikami, who appoints her as the new spokesperson for Kira. Light's relationship with her from university allows him to make personal contact with Takada again, which allows him to discreetly pass instruction on to Mikami.
