Summary
October 18th.

Russia declared the beginning of the 3rd world war.

The conflict between Academy City and Russia will expand to the level where it will involve all other nations. The ones behind the scenes manipulating it all are the last member of ‘God’s Right Seat’ and the bearer of the "Holy Right", Fiamma, and the man who watches and plans in secrecy, unknown to the rest of the world, Aleister Crowley.

In the fires of the world war, there is a group of people that runs to and fro. A high school student of Academy City, Kamijou Touma, aiming to free an unconscious Index from the grasp of Fiamma after the incident of fighting over an artifact in England. The strongest esper, Accelerator, aiming to save Last Order, who’s in a critical condition after the mysterious appearance of the entity ‘Aiwass’. Originally a lackey for the group ITEM, Hamazura Shiage, aiming to save Takitsubo Rikou who is physically weakened after she overdosed herself on the ‘powder’ that boosted her abilities.

The three of them holding three different thoughts, three different paths that should never meet, converge in Russia. And what awaits them there is…

Academy city in response says that they can't sit idly when they have the power to stop the world from going into war, and start invading Russia. Japanese government don't want Academy city to retaliate, but shuts up after Academy city shows them a clip Russian shooting missiles down, after that saying "we don't need to protect you, you know?"
