One day, Touma receives a phone call from his teacher, who says that Touma is an idiot and must attend extra classes. As if that isn't weird enough, he finds a stunned, chibi nun sprawled across his balcony named Index-tan! Like Index in every way, Index-tan bullies Touma, eats excessively and becomes easily overexcited despite her small stature. Adding to the chaos, Accelerator seems to have discovered a soft side, Kaori gets drunk at the after show party and Komoe has serious problems visualizing a kawaii angel. Whatever is going to happen next?!
I enjoyed A Certain Scientific Railgun, so I muddled through the much less entertaining A Certain Magical Index just so I could pick up the necessary context. It turned out it was worth it just to get in on the inside jokes in these shorts. They were hilarious. There's no story or anything like that. It's just a bunch of rapid fire gags, but they are the best shorts I've watched thus far. Unfortunately, you need to watch Index to get them. It's probably worth it
