To-Oh University

 To-Oh University  (東応大学, Tōō Daigaku ) is a university located in Japan.

Light Yagami attended this school, and L later joined in order to investigate Light for himself, posing under the alias of "Ryuga Hideki", the same name as the famous popstar. Both Light and L got perfect scores on the entrance exams.

Light met Kiyomi Takada at the university, and began dating her to divert any suspicion from him. Takada later went on to get a career as a news caster, and was eventually contacted by Teru Mikami, who appointed her as the new spokesperson for Kira.

Shingo Mido also went to To-Oh University.
