Ok caught up with the manga (or the translated chapters atleast,) and poor Zenkichi, I think Medaka has gone too far now, and don't understand Zenkichi not will to work part of a team, this is the same person who is still friends with Hansode even when she went against Medaka. If it's one thing I find strange about the manga is the charactors change too much almost appear OOC, specially this arc.
Maybe i'm failing to understand the manga, I don't want to have to read this a third time, because I did have to read it all over once before because I was completely lost as to what was going on....hopefully the Anime is not just yor bogstandard 12 episode series and a long one, so I can watch it all and understand what's actually going on.
Zenkichi don't feel so OOC in my opinion, actually, let's face it, most of us would act the same way as him if we were on his shoes, there are just times when we are too full of ego or pride to let other persons help us, so his action are actually quite understable, but about Medaka she really feels OOC, or pehaps she was aways a b*tch and we never noticed, regardless, I took a peek at the latest chapter and...
It seems Zenkichi grew tired of Medaka bossyness and want to chalange her to become the main character, and when he confronts her, she once again acts OOC (or like an b*tch, well, whatever suits your taste better) and hit him from his back like an coward, and the chapter ends with this, with the two seemly about to kick each other arses.
Ah, and here is an link for the latest chapter were this happens:
