Also Mr. Edogawa is my favorite teacher because he physically lacks eyeballs and because all he ever talks about is magic. What is he even supposed to be teaching?
Don't know if you know this already from your Persona 4 adventures, but when the P4 cast goes on the class trip to visit Gekkoukan, it's Edogawa who gives you a guest lecture on the creation myths of Japan (Izanagi and Izanami, etc.) He can be worth paying attention to sometimes.
