Toaru Majutsu no Index Light Novel Volume 22 was first published on October 10, 2010. It is the last novel of the epic three-part novel storyline depicting the events of World War III and the grand finale and the last novel of the original novel series. It features the conclusion of the war, the defeat and change of Fiamma of the Right, the defeat of Archangel Gabriel, the defeat and the relief of Mugino Shizuri, the salvation of Last Order and Index, and the dismantling of the Dark Side of Academy City. The novel ends with Kamijou Touma once again "accepting" death, Laura Stuart discovering for certain that Aleister Crowley is alive, and Index looking for Touma.
With all the events in the novel, it is considered as the halfway point of the novel to be continued in the next novel series, New Testament.
The desire to protect a girl, will the three boys' feelings reach through? The story of Science and Magic, finally at the climax!
The last member of the Roman Catholic Church's dark side, "God's Right Seat" — Fiamma of the Right. The giant fortress "Star of Betlehem" floating through the air space of a Russia engulfed in the Third World War.
It was said to "save" all of humanity not just believers of Christianity, but had the meaning of bringing destruction of unprecedent levels in human history. While Fiamma calls this "purification", the three boys keep fighting, holding their seperate feelings.
Hamazura Shiage, after finally curing Takitsubo Rikou, moved to protect the Kremlin Report before anything happens, and runs into his old nemesis Mugino Shizuri.
Accelerator having barely left the Archangel Misha, in order to save Last Order comes upon "A Certain Solution". However that was surely a prohibited method.
And Kamijou Touma, in order to stop the "Star of Bethlehem" plan, in order to save Index, challenges Fiamma alone...!
