In a world where science clarifies supernatural powers. In a huge college that has power development in its curriculum. To a resident high school student, Kamijou Touma, a pure white sister appears. She calls herself "Index" and says that sorcerers are chasing her. Thus, Kamijou Touma enters the world of the occult.
This Anime has a very good animation & character design. Althoug the story isn't special but if you watch "Railgun" after this you'll know that this anime has a interesting story line.
The base story is about supernatural power (Psycho power & Magical power) but still has good action-fighting scene.
In my country this anime has some character that favorite and still talk about untill now.
