I really need to go back and finish S2...it's one of those shows where I had stuff going on, wasn't able to keep up as it aired, and now I don't even know how to start again because I've completely forgotten how the tangled web of politics fits together. Maybe there's a good diagram explaining the state at the beginning of S2 and I can just start from there, because I really don't want to start over.

Looks like there's a light novel adaptation with one volume scanlated, so I might start there--should at least get me partway through S1. Really ought to up my Japanese vocabulary so I can start tackling raw novels.
