It just goes to show that even a tiny arc that didn't do much but serve as reintroducing the primary cast was largely better than long arcs of Railgun. The world of Index just isn't the same without the clash between magic and science. It was simply more interesting.

I had forgotten the extent of how terrible Touma's life is due to that curse of luck. He comes out of this adventure with no homework done, a completely trashed apartment (even Stiyl never burned his down), and presumably a large bill from the family restaurant.

Concerning Mikoto, I've always liked that she comes off as her own age in Index. She acts much more like an impulsive middle school girl with a crush than the more mature and responsible (yet irresponsible) way she's portrayed in Railgun. What does a super-powered little lovesick girl do when she gets ignored? She lashes out and destroys a trash-bot, then doesn't really know how to respond next and gets all flustered.

I also give much respect to the oft-maligned-here Index. She's a great counter to the dry Touma. The funniest parts with her is when she acts all mature because while she is a nun and full of wisdom despite her age, it is so out of character with the view Touma normally sees. Similar in age to Mikoto, she also serves as a really good rival to Mikoto for Touma's attention and possible affections. It is especially insulting to Mikoto because Index is so needy (needing rescue/food), childish, and annoying. It is a harsh reminder to Mikoto, who is also needy (emotionally) and very childish.

Animation was good, OP wasn't bad, ED was meh, and the little background actions throughout the episode of Sphinx were a nice touch.
