Biography
Persona 2: Innocent Sin
Tatsuya Sudou was a senior at Seven Sisters High School when Kashihara was a teacher there. He was a nervous, twitchy fellow who was terrified of his cruel father. He also heard voices in his head, which made him even more nervous. He and Kashihara became friends, though; Kashihara thought that Sudou's voices were direct messages from the Maiyan aliens and wrote them all down into the book In-Laqetti.
