Well as I alluded to, Satoru does in fact have a place for students to purchase food, though it's pretty lowbrow stuff. Mainly various types of breads and rolls.

Edit: Also all the new characters have been added to the OP and the list has now been divided by years, because SOMEONE had the idea and had to make me work *grumble grumble*

Also for you second and third years who apparently don't really have anyone to interact with, if you want me to come up with some NPCs for you just ask. Or you could hunt dow-I mean accidentally run into your underclassmen in the halls or something. Entirely up to you.
