What do we know about Nagi Springfield
I know we'll all end up having this discussion anyway, so I thought I'd start it off already.
We all know that Nagi is know as the thousand master, even though he admits to Angelina when he catches her that he doesn't know that many spells anyway. But what I find puzzling is that he says he is a dropout from the academy, which makes me wonder why he'd drop out because he seems very capable and heck all his companions look up to him (from what I could tell).
Could it be that Nagi's potential even in unpolished form is so extrodinary that it surpasses any expectation to Negi ?
