A Certain Magical Index
とある魔術の禁書目録 (original)
In a city where science is used to develop supernatural abilities, Kamijo's powers are laughably weak. Luckily for Index, the guy's got a lot of heart. Index is running from sorcerers who want the magical knowledge stored in her memory. Kamijo wields the magic-negating power found in his hand against anyone who threatens Index - but it's his loyalty that offers the best hope of keeping her safe.
