From the Normal Norman general.
 
Good evening. It seems our favorite normal teenager has gotten himself an exclusive scholarship to an elite academy!  
…Along with most everyone else in his school.  
Day 1 starts off. Norman arrives at school by train and heads in. He says hi to a couple students in passing as he heads to his classroom. There, Purple is waiting, along with a few others. He talks to Purple, and oddly enough, she responds with >pic related.  
This is odd because she and Norman have no prior connection within the game, but apparently they do! Somehow!
