Wow so much 4th wall breaking!
Also I figured that was Anshin'in's whole deal, that she WANTED to loose and to die because she had been around for forever, and thus was tired.
I wouldn't have been surprised if this was the final chapter. It really had that sort of feel. Dunno what happens in the next 50 but I hope the actual ending can top this.
I love how Medaka is mad not because of Anshin'in-san's scheme but because she indirectly insulted zenkichi by saying that him beating Medaka is an "impossibility".
