Shinyaku Toaru Majutsu no index synopsis
The Third World War came to an end after only two weeks. Both Accelerator and Hamazura Shiage have returned to the people they care about after overcoming their individual conflicts. The world is at peace and Academy City continues to be normal as the wizards focus their efforts on repairing the damage suffered from the war.
In this calm, however, someone is missing. Someone who used his right hand to save a young girl while filming the war on the move: the "Imagine Breaker", Touma Kamijou. However, the disappearance of the self-proclaimed "normal student" has not affected most of the world as the temporary peace will soon be broken as new threats, both espers and magicians, emerge worldwide. Now the heroes of World War III must go back into battle and face some of the most powerful enemies imaginable to protect the people they care about.
