Professor Taniyama
About
A professor at the faculty of law that Yoshino and Akio attend. He specialises in civil procedure. He's friendly and takes good care of his students. He is aware of Yoshino and Akio's relationship and often teases them about their combination of a mediocre student and a talented one who wants to become a lawyer. He was a classmate of Narita, the director of a law firm in Tokyo and he helps Yoshino land an internship there after her graduation.
He gets worried after he learns that Yoshino is having trouble with her mental health, but is surprised when Akio tells him that its cause could be her cheating in their relationship.
