(献身的な子羊は強者の知識を守る, Kenshinteki na Kohitsuji wa Kyōsha no Chishiki o Mamoru) (聖ジョージの聖域 (セントじょーじのせいいき), Seinto Jōji no Seīki, "Sanctuary of St. George") (竜王の殺息 (ドラゴンブレス), Doragon Buresu, "Killing Breath of the Dragon King")
She is often elated by a variety of things and is slightly ignorant and curious about modern technology. She usually is gentle and polite with people and has a kind nature, but is also a selfish spoiled brat when together with Tōma. She is also abusive towards him and hypocritical in nature, chiding him for doing things she doesn't like, yet does the same things herself. She constantly jumps to conclusions without learning the circumstances first and constantly punishes Toma, wrongfully, by biting him or starting arguments with him, much to his confusion and exasperation. She also has a large appetite and uses any excuse to get food from anyone and likes watching an anime series called Magical Powered Kanamin. She has strong feelings towards Tōma and even confessed her love after hearing Tōma lost his memories because of her; however, he avoided answering by changing the theme of the talk since he has no idea about what kind of feelings he used to have with Index.
In New Testament, Index eventually reunites with Tōma when he reappears in Academy City after the events of the Third World War.
Accelerator's unique ability makes him the subject of an experiment attempting to create the first Level 6 esper: according to the city's best supercomputer, Tree Diagram (which was unprecedentedly destroyed by Index's Dragon Breath), this feat could only be achieved by killing Misaka Mikoto, the Railgun, 128 times without a single failure. Since it was impossible to procure 128 Railguns, an alternative plan was formed to "level up" Accelerator by having him kill 20,000 skilled Level 3 espers: the Misaka clones. He willingly joins the experiment to gain a reputation as the most powerful and feared esper so that no one would be foolish enough to challenge him. His desire to achieve this goal leads him to kill many who got in his way. Mikoto tries to stop the experiment to save her sisters, but it is Tōma who finally does so and defeats Accelerator after discovering his weakness: Accelerator was physically weak because of his total reliance on his powers and his overconfidence in his esper abilities. Therefore, Tōma beat him with his Imagine Breaker and street-fighting skills.
After his defeat in volume three of the light novels, he reappears in the fifth novel where his past was also revealed. He was taken to Academy City at a young age when his powers were first discovered but because of the lack of understanding of his powers, people fear him and in some cases tried to kill him. Due to the many attempts on his life and the numerous experiments performed on him, these events shaped Accelerator into a sadist and made it difficult for him to trust anyone except for Kikyou Yoshikawa, the only scientist who ever cared about him and saved his life. He also takes a more heroic and fatherly role by protecting a young girl named Last Order, the last Misaka clone who believes through the memories of the Sister clones who fought him that Accelerator is not a bad person and actually never wanted to hurt the clones but tried to merely intimidate them into not fighting him, a theory Accelerator dismisses. In the aftermath of the incident, Accelerator is shot in the head by Ao Amai and acquires aphasia due to brain damage. The injury also affects his ability but Heaven Canceller jury-rigs a choker-like device to his brain, allowing Accelerator to tap into the Misaka Network to make up for his injury and function normally. He can also switch the transmitter to full power, restoring his ability for a maximum of 15 minutes in the beginning, but the time is later extended to 30 minutes by an update to the device. Toward the end of volume 13, Accelerator begins to "awaken" after nearly being killed by Amata Kihara and his aphasia is somehow temporarily cured. He truly "awakens" in volume 15, gaining black wings when fighting another "awakened" level 5, Teitoku Kakine. In the events of the 19th novel, he meets Aiwass, a higher dimensional being, summoned to their plane of existence. Aiwass explains to him when AIM entities like him are manifested, Last Order is heavily strained and may die if left untreated. To help Last Order, who has collapsed from sustaining Aiwass, Accelerator follows Aiwass's advice and heads to Russia during World War III in search of Index, unaware that he has met her before.
In Russia, after being ambushed by Russian mages, he acquires the "Goatskin", a mysterious document sought after by both Academy City and the Russian government that has the knowledge about the Archangels and Heaven, and later runs into a Misaka Worst clone, learning that Aleister intends to eliminate Last Order, now obsolete to create a new Misaka network. Despite being more powerful than Misaka Worst, Accelerator is unable to bring himself to harm another Sister clone after the Level 6 experiment and becomes mentally unstable after the clone attempts to kill Last Order and later tries to kill herself. Accelerator goes on a rampage until Tōma arrives where he turns his frustration regarding Last Order's condition onto Tōma and a fight ensues between the two. After Accelerator is defeated again, Tōma uses his Imagine Breaker to stabilize Last Order and leaves a note informing him of Index's true whereabouts. Later, he joins forces with Elizarinian soldiers and Misaka Worst to find spies in their country and fought Archangel Gabriel along with Hyōka, where after studying the Goatskin, he learns to understand the angel's language and turning himself into an angel as a side effect. With his new powers, he is able to decode one of Index's songs and was finally able to cure Last Order but is injured in the process.
After the Third World War, Accelerator is given his freedom with the help of Shiage, after he threatens the Academy City's administration to leave him, Last Order, and Misaka Worst alone and orders them to stop all illegal black projects in the city. However, both he and Shiage actions anger a new group of espers called the "Freshmen" who are aware of the existences of Magic and sees them as an obstacle in Academy City's war against the Magic factions.

During the 15th novel, Team ITEM is involved in a war between the various underground organization where Shiage helps them by providing transport by stealing cars around the city. But when Team ITEM is defeated by Team SCHOOL led by its leader, Teitoku Kakine, Shizuri Mugino, the leader of Team ITEM, wants revenge for being humiliated no matter what and forces an injured Rikō to use her powers to find Teitoku despite the fact that repeated use of her powers will kill her. In order to save Rikō, Shiage fights against Shizuri and despite the odds, he manages to defeat Shizuri by using her pride and powers against her. However, this unexpected incident becomes a thorn in Aleister's plans as there was no way Shiage could defeat Shizuri as she is a Level 5. Seeing him as an unpredictable anomaly that will disrupt his future plans, Aleister puts a bounty on Shiage and orders the forces of Academy City's dark side to kill him. Ironically, he is saved by Shizuri, who survived their battle and now has a sense of twisted love for him (declaring she will castrate him as her sign of affection). She lets him and Rikō escape Academy City by stealing a jet and shoots down his pursuers, declaring that he is her prey and hers alone.
Shiage and Rikō escape to Russia only to find themselves in a war between Academy City and Russia. After being saved by Acqua of the Rear, Shiage and Rikō head to the nation of Elizarina where Rikō is partially healed by Accelerator and aids Acqua. In order to protect a document called the Kremlin Report, Shiage and Rikō head towards the same nuclear military base that Mikoto went to while they were being chased by Academy City forces and later Shizuri. However, Shizuri collapses from over-exhaustion as her fragile body is suffering from the effects of using too much Body Crystal, a dangerous drug that Rikō uses to activate her powers. Unable to see her this way, Shiage begs Shizuri to let go of her pride and see reason and be the Shizuri that use to care for her teammates which strokes a cord within her and makes peace with him as she protects him and Rikō from the rest of the invading Academy City forces. After capturing a member of the Board of Directors who led the Academy City forces and torturing him, he reveals to Shiage a document called the Parameter List, which reveals that the Academy City administration has been secretly interfering with the Power Curriculum Program and preventing most of the city's students from gaining or raising their powers.
After the Third World War, Shiage is given amnesty and the assassination order on him removed thanks to Accelerator and makes a deal with the Academy City's administration, where he will not expose the truth about the Parameter List and he, along with Rikō and Shizuri is allowed to return to Academy City to reform Team ITEM. However, his and Accelerator's actions have made them enemies with a new group of espers called the "Freshmen" who is aware of the existence of Magic who sees both of them as an obstacle in Academy City's war against the Magic factions. After Tōma and Leivinia help him and Accelerator against the "Freshmen", Tōma introduces them to the world of Magic and involved in an operation in Hawaii.
