Little, Brown Book Group Certain Magical Index, Vol. 1 (manga)

Touma Kamijou just can't catch a break. He might live in Academy City, a place full of more super-powered students than you can shake a stick at, but his only superpower is his supernatural lack of ability. He wants nothing better than to keep a low profile, but when a girl named Index comes into his life, it gets more complicated and dangerous than ever!
