Index 21

As unbelievable as it might seem, I believe this episode actually lives up to the expectations established with the premise of the series! Biribiri being tsundere and shooting a railgun, loli-sensei driving, AIM and all the "OVER 9000" jokes it brings, the teleporting lesbian fighting and being a perverted lesbian to her Onee-sama, Index being Index, mysterious magician, foreshadowing, and fanservice.

I gotta say I was really pleased with this episode, it had a nice amount of almost everyone in it. Komoe-sensei driving a car, lmfao. Of course 'biribiri' always delivers something, I am hoping for something at least this good in the next episode.
Kazakiri....nomnom ....those glasses and that hair accessory
