First, Nanaki is in her class! The prospect of having a terror teacher excites me! I might have mentioned in an old post that he was dreading group work for the class :B (It can be unwritten no problem!) I see Field Tactics is going to take priority in his class work. He is going to be convinced that Fujin is one of those instructors who is not going to care if he has a 'condition' (not that he really expects special treatment) but this would make him work doubly hard for Fujin anyway just so she wouldn't say he's underperforming.
Sabin and Fujin could be interesting too! He's all about dialogue and understanding so he's likely going to be peeved with all the yelling and anger issues and one word replies, either he'd say something about it or just take that cue to avoid her.
