Season 1 - Kamijo is a student in Academy City, where people use science to develop supernatural abilities. The guy’s got a lot of heart – luckily for a young nun named Index. She’s on the run from a sorcery society that covets the astonishing 103,000 volumes of magical knowledge stored in her memory. When Index stumbles into Kamijo’s life, she find a faithful friend and protector, and while Kamijo’s easily the weakest kid in Academy City, he’s got something else going for him: the Imagine Breaker, an unexplainable power stored in his right hand that negates the powers of others. With scientists and sorcerers attacking from all sides, the Imagine Breaker will definitely come in handy – but it’s Kamijo’s loyalty to Index that will be his greatest weapon in the fight to keep her safe.
Season 2 - Toma and Index are back in an action-packed season that brings back the characters you love while introducing a host of new spell-wielding allies and enemies. Protecting Index has never been easy, but when several groups begin to fight over sacred magical relics, keeping the nun safe becomes downright impossible in the city where science and the supernatural go hand-in-hand.
