Misaka Mikoto/Chronology (Shinyaku Toaru Majutsu no Index)

Freshmen Arc
In the first volume of New Testament series it is hinted that Hamazura Shiage bumped into her in the 7th district, but was ignored, showing that she was still depressed and worried about Touma.

Homecoming Arc
Some time later, she decides to hack into Academy City database to find out more about Touma. However, she is surprised by a heavily intoxicated Touma who gives her a box of sushi. Touma then begins to leave, along with the many other girls that appeared with him, and she ends up following him to his dorm. Mikoto and the other girls are persuaded to leave but not before Mikoto forcefully obtains a promise to explain everything.

She later catches up with him on a bridge after the excitement dies down and returns his phone strap, telling him not to lose it since their match. He states that the reason he can't stand still is due to the impending chaos that is about to befall Academy City. She then tells him that she will not stop him because she knows he won't listen to her anyways, but just as he is about to leave, she grabs his hand and states that this time he is not alone.

Hawaii Invasion Arc
After homecoming she travels with Touma to Hawaii, where they encounter a GREMLIN agent, Cendrillon, at the airport and launch an attack her. She and Touma later get seperated and she ends up with Misaka WORST where they have a chat and she gets severely teased. Eventually, she and Touma encounter Roberto Katze, who offers his help. So, to stop the Trigger they head to Pearl Harbor. Eventually, it results with her and Accelerator fighting off Trident forces that try to invade.

Eve of the Festival
Thor impersonates Mikoto as a means to get close to Kamijou Touma. By utilizing the information gained from the security cameras during the Hawaii Invasion Arc, Thor successfully adopts her character and personality and uses it to trick Touma.

Apparently not busy herself, Mikoto's first actual appearance in the arc is as an unofficial visitor of Touma's school, looking for him there. She is nervous because she stands out too much. Her actions, however, are noticed by Tsukuyomi Komoe, and they meet for the first time. Here, despite knowing that Mikoto is a Level 5, Komoe doesn't know what she looks like. Komoe tells her that unofficial visitors to the school are not allowed by Anti-Skill. However, Mikoto completely ignores her, and assumes that, since she looks like a child, that she too is a visitor like herself. Komoe is flabbergasted as Mikoto assumes that she is an elementary student and refers to her as such. As Mikoto is impressed by Touma's school's preparations despite its modest accomadations, she and Komoe overhear Seiri shouting that Touma has been arrested by Anti-Skill (due to his little scuffle with Thor earlier).

Mikoto later apparently searches for Touma and somehow ends up in the area near the Windowless Building. She spots and demands answers from him, such as why he is not helping his school for the Ichihanaransai, regarding on how he was arrested by Anti-Skill, and how he managed to get back from Hawaii. Touma, however, believing that the Mikoto before him is still Thor (who changed into Mikoto before), tells her to stop joking around, confusing Mikoto. Touma then demonstrates how terrible "Thor's" disguise is and touches Mikoto's chest, ceaselessly bewildering her. Touma notes on how they feel so real, to which Mikoto stutters to say that they are not pads. Tired of this nonsense, Touma leaves Mikoto and tells "him" to stop joking around and get to the rendezvous point.

During the Festival
8 AM during the start of the festival, Mikoto decides to come back to Touma's school. When she approaches the main entrance of the school for the trial enrollment, she bumps into Misaki, who was using her ability to make the crowd chase after Mikoto. She then constantly cursed Misaki for always teasing her but soon stopped as she started to wonder what she was doing there in the first place. However, she quickly cast away that thought as the crowd caught up with her again.

Thor later spots Misaka Mikoto from a water tower, and deeming her to be useful to aid Touma, calls out to her.Calling her by Miko-chan, he immediately gets her attention. Thor then shows Mikoto a footage of Touma being tended by Cendrillon, to which Mikoto demands Thor to tell him where he is. Mikoto herself tries to confront Touma. She approaches Touma still being taken care of by Cendrillon. She attacks him, and is surprised that he did not block it. She later discovers that he has gunshot injuries and feels sorry. Nonchalantly, Cendrillon comments on Mikoto's attacks but says that it is only natural for her to get angry as Touma is the only clue leading to GREMLIN. Touma seeing this opportunity, asks Mikoto to translate for him. Here, the both of them discover Cendrillon's circumstances, on how she snuck into Academy City, her new abilities, as well as the reason she got so small. The last one piques Touma's attention, as there is still leftovers from her reconstructing her body, which can be made into whatever they want. Touma asks Mikoto to tell Cendrillon that he needs her help in constructing a brain that would prevent Fräulein Kreutune from eating a person's brain. Only now did Mikoto know of Cendrillon as the same one from Hawaii, but Touma's urgency takes precedence and Mikoto do what she is told. Cendrillon tells Touma that she doubts she can help him as her vengeance with Marian takes precedence, and that the leftovers, if lost, will no longer able to remake herself back to normal. Hearing Marian's name however, Touma casually comments on how he defeated Marian back in Baggage City. As Mikoto translates it to Cendrillon, she is caught by surprise by Touma's actions, and unreasonably concludes that Marian must be dead, but he makes no attempt to amend her misinterpretation. Cendrillon clicks her tongue, noting that not only did Touma save her life in Baggage City, but freed herself from her revenge, lamenting on the fact that he was supposed to be her enemy, but has grown more indebted to him. However, Mikoto refused to translate what she just said. Touma pleads Mikoto to continue translating, and she acquiesces. Cendrillon tells Touma that she will pay back her debts, and asks Touma what she needs to do.



Leivinia soon finds Fräulein Kreutune in the multi-level overpass, and is forced to engage against Kamijou Touma for her fate. Silvia and Brunhild that was supposed to support her, are confronted by Thor of GREMLIN and Misaka Mikoto of Academy City, respectively. She is complaining to Thor on why she has to help him. Thor explains on how people have gathered together to beat the already injured Kamijou Touma, and then abduct a woman named Fräulein Kreutune, use her for their own purpose, and then kill her. He then asks what Mikoto is going to do, to which she sighs and mentions that it is the same pattern as always. Mikoto mentions on how Touma has not changed after disappearing in Hawaii and arriving in Baggage City. Thor tells Mikoto that despite what happened in the city there, Touma still managed to save lives. Thor says that he is just as much to blame for the events happening, and tells Mikoto that Touma is trying to finish things with Fräulein Kreutune, the primary cause of all the events that are currently happening in this. He asks if she will support him or get in his way. Mikoto clicks her tongue and says to Thor that he owes her, but Thor tells her that is supposed to be directed to Touma. But Mikoto says that doing so is embarrassing, as such she's saying it where he can't hear her. With that little banter over, Mikoto faces her enemy, while Thor faces his own.

And so, magic and science clashed, Brunhild of the magic side, one of the 20 Saints in the world, against Mikoto of the science side, the third ranked Level 5 esper of Academy City. Despite the fierce titles bestowed upon the two, the battle seemed one-sided, for great speed Brunhild held, and her steps if she wished were faster than sound. Brunhild chaged towards Mikoto and swung her sword down her like a steel fan. But Mikoto reacted before the blow, and with her powers moved a part of the road they were on, putting Brunhild's aim off, but its power was immense still, and many glasses were shattered the instant it fell. Brunhild questions Mikoto's ability to know where she was despite her speed, not knowing that her powers allow to control iron sand on the road's surface and allow her to see her footprints. And with that same iron sand did Mikoto use to consume Brunhild inside like a storm of needles. But no harm came to Brunhild, for she swung her claymore in a circle, and the iron sand was blown away in a roar. The force her swing threatened to knock Mikoto down, but she escaped by magnetizing a wall between before it struck. Mikoto tries to gather the iron sand once more, but Brunhild came upon her and aim the sword upon Mikoto's neck. Mikoto used her powers to forced the blade to halt, but Brunhild's strength overcame it for her to swing it. But it was enough time for Mikoto, and a lightning spear struck the sword and Brunhild. Mikoto did not allay her attacks, for she swung towards Brunhild many reinforced concrete objects. However, Brunhild recovered from the shock, and with her strength stopped the mass of objects that Mikoto flung towards her.

As if acknowledging Mikoto as a worthy foe, Brunhild speaks to her, asking why she is participating in this conflict for Fräulein Kreutune if she had little to do with magic. For a great risk did Mikoto bring upon herself when she wraps herself in the core of GREMLIN. Mikoto tells Brunhild that she doesn't want to hear from someone who is trying to kill her, and straight to the point, does not know nor care about the big picture surrounding their conflict. Moreover, she says that she has no good reason to be fighting. However, Mikoto says that there is not a need for a good reason to save a friend, as what her friend once said, and now, she will support him in spite of the dangers that will befall him. With that, Brunhild cut down her obstacles and made an opening for her with her sword, and the same time, Mikoto swung her iron sand sword. Colliding, Mikoto saw that her vibrating iron sand sword could not slice the claymore, and released it. She then took a coin, and fired her Railgun towards Brunhild, shouting that she has her own reason to save Kamijou Touma.

Despite the apparent danger of letting her guard down against Brunhild, Mikoto took the time to use her electromagnetic powers to control Leivinia Birdway's gun before she could fire it. This and Thor's later use of his fusion arc blades to cut up the road between them, allowed Touma to recover enough in order to fight Leivinia anew.

However, with the defeat of Leivinia Birdway at the hands of Kamijou Touma, Brunhild stops her attacks, her sword covered with various objects that Mikoto stuck into them to slow her down. And Mikoto did not dare take advantage of the opening. Mikoto asks what's the matter, to which Brunhild says that the issue has been resolved, and she is unsure if she should continue fighting, head over as reinforcements, or view the situation as unfavorable and make preparations to reorganize. As what happens later, Silvia takes the last option, and the conflicts in the multi-level overpass ends.

Agitate Halation Arc
Mikoto first appears when returning to School Garden after a long day in a research facility. She jumps from rooftop to rooftop, but stops to discover that Touma is in School Garden, a place where boys are not allowed. Seeing him on a rooftop, she attempts to pull him towards her by magnetizing his belt, but he negates that with his right hand and falls into the gap betwen the buildings. She is worried at first but then realizes that he is fine and proceeds to continue her pursuit. She goes into the building but finds Touma not there. She soon discovers Misaki's clique acting suspicious and tails them. However, it is revealed that Misaki has tricked her by hiding Touma inside a bunch of flowers.

After the Agitate Halation Project has taken effect on the "heroes" in Academy City and they have begun gathering in Learning Core where Fremea Seivelun is located, Mikoto tags along with Shokuhou Misaki who, like Mikoto, is searching for Touma. Misaki takes control over some of the heroes and diverts them to Mikoto, who then proceeds to take them down, much to her annoyance. Misaki tells her that Mikoto has no reason to be there unlike her because she was abandoned before she could see the incident with Touma through its end. Mikoto points out that it is her reason for being here as well. Hearing this, Misaki challenges Mikoto that whoever gets to him first gets to do whatever they want, leading to Mikoto being confused about what she means by "whatever they want".

Later, Mikoto experiences firsthand the resourcefulness of heroes. She tells Misaki to help as she can use her power to stop them without making a scratch at them, but Misaki ignores her. Misaki is later nearly overwhelmed by an attack by both a leopard and the heroes. She asks Mikoto to help her despite Misaki ignoring Mikoto's complaints just a few moments ago. Mikoto tells her that she will but only after the leopard has eaten her "extra fat" in the chest area.

Due to the peculiar gathering of all the Level 5s in the location, it can be assumed that Mikoto may have been influenced by Agitate Halation. Neither Mikoto or Misaki are able to meet with Touma after the incident.

Lance of Gungnir Arc
On the way to school, Mikoto stood silently with one of her cheeks twitching. She saw Touma sitting on a bench with girls clinging to him then instead of going biribiri due to the unpleasant sight, she just muttered to herself that she is sick of this position. Suddenly an adult woman in showy suit spoke to her and she recognized that this woman was under Misaki's control. Misaki then teased her regarding Touma and asked if she wants to know what's going on to which she replied that she isn't at all interested. Misaki then provoked Mikoto by saying she will approach him, ask him and seduce him by controlling more girls stating that he will at least like one of them. Mikoto then panicked and told Misaki that if she continues doing this, there would be chaos. She then controlled magnetism to lift up the bench where Touma and the others are sitting and sent it to the other side of the river. Mikoto then landed on the bench and demanded an explanation from Touma.

Mikoto tagged along with Touma and the others and they were at District 23. Lessar and Leivinia Birdway then proceeded to shop for swimsuits so as to prepare to go and hide to a resort after defeating GREMLIN since they would likely be the target by the churches after everything is finished. Mikoto then grab Touma's collar and shook him while asking him an explanation for all of this. Leivinia and Lessar insisted on going to "50% Less Skin Covered" swimsuit store to which Touma refused and instead suggested to have voting to which store to go. Touma then provoked Mikoto and thus got her vote. Touma won and they proceeded to the other swimsuit store (Tropical Bright Girl). On their way, Mikoto then asks Index if these crazy things always happen to him to which Index responded that this is just the third link of the chain. Touma was looking at the gadgets that are displayed with disappointment since they were old models. Mikoto then told him that it is natural in duty-free shops so as not to allow Academy City's technology to leak out and then argued with Touma that he was just disappointed because he won't be able to see those girls in sexy swimsuits to which Touma denied fully. As they enter the store, Index said that she would be fine with any store as long as it has food and Touma reacted that whether she has finally reached the point wherein she will also eat swimsuits or cellphones as well. Index then exclaimed that she can smell cafe's and bread shops around. Touma was amazed at her skill when it comes to food and Index told him that food doesn't change and as long as there is food, she will eat it. Mikoto then said to Index that she must not underestimate the advances made by science and said that even a trash meat in Academy City is much better than the average in the outside world. Index then screamed at Touma to which Touma responded that he can't afford such a high class meat. They then entered the swimsuit shop and Mikoto proceeded to buy a swimsuit so that she would be ready and won't be in a hassle in case she go to the newly opened indoor pool in the leisure facilities of District 6. Touma then suggested that she just buy in a sports shop but Mikoto insisted that she would buy now to avoid hassle. Mikoto then proceeds on choosing a swimsuit and warned Touma to not peek on her to which Touma responded that he won't. Mikoto then shoot a lightning spear toward Touma which he negated and told him to pay attention on what she is saying. She then decided on a swimsuit and told Touma to not look at it. Touma then pointed out that it looks normal and she doesn't need to hide it but Mikoto insisted that its design is different then suddenly the cloth from the chest down to the abdomen peeled off much to both Mikoto and Touma's shock. Touma then urged Mikoto to put it back where she got it. Index, Leivinia and Mikoto then caught Lessar who was overcome by shock due to Touma defeating her sex appeal and Touma holding a swimsuit and misunderstood the situation. .

They met Kumokawa Maria at the airport and asked Touma what does he do to know so many girls. After recieving word that Sargasso has already been located, there was a low rumbling in the earth. Touma ran off with Index and Mikoto following him. Mikoto then told him that her mother leaves in Tokyo and this has something to do with her to which Touma let her go with him. Mikoto and the others proceeded to ride an electronic cart to the plane. As the plane left Academy City, it was sliced in half by a giant dragon. Mikoto and the others were mercilessly thrown out into empty air.

GREMLIN invasion of Tokyo
As Index and Mikoto are falling from the sky, Mikoto stopped using her parachute and caught Index who is chaotically rotating as she fell. Mikoto then controlled magnetism and landed vertically on the wall of a giant train station building while holding Index. Mikoto was dumbfounded that the place was so packed with people to the point that she can't see the sidewalk. Index then told her that it was GREMLIN's doing. Suddenly, a {{Nidhogg|giant dragon]] flew over their heads but did not attacked them. Mikoto then tried to use her cellphone but it was of no avail since the lines were apparently overloaded. Mikoto then started to move from building to building using her magnetism and while still holding Index. They are heading for Sargasso since Mikoto thought that Touma will probably head there. While moving, Index then warned Mikoto to watch out and they landed perpendicularly on the side of a high rise building. As soon as she did, countless of sparks appeared floating down and each spark struck the glass wall and produced pillars of flame that took form. Index then explained that it is the Muspell from the Norse Mythology to which Mikoto doesn't understand.

While still holding Index, Mikoto used her magnetism to jump from wall to wall. They were being pursued by the Muspell but they tried to escape them. Mikoto then asked Index if she knew where they are right now to which Index responded that she doesn't know. They then wondered what happened to Touma then suddenly they saw an Academy City bomber and realized that Academy City has already made their move. They also saw an eagle-like creature that flew to which Index said that it was Hræsvelgr and explined it to Mikoto. Suddenly, the creature fell toward a wide open space.

Mikoto while holding Index just saved Touma just in time before he is about to fall. Index was then released by Mikoto and she proceeded to scold him to which Index said that it won't change Touma. Index then told Touma that she would be going this time and he won't be backing down no matter what he says. Touma's cellphone then fell down while some button was pressed and he heard his mother's voice saying that she is fine and they don't have to worry. After hearing that, Touma then told Index and Mikoto that the opponent he's facing now is Freyja and he asks them to lend him their power so that he would be able to save both Freyja and the mother to which the two responded that he leave it to them.

Just as Freyja commanded Nidhogg Vol. 02 to attack them, Mikoto attacked it using her ability and repeatedly fired railgun at it at point blank range. The dragon was stopped and Freyja was dumbfounded. She got separated from Touma and Index after the fight with Freyja. Mikoto fell from the sky and used magnetism to land on the metal railing alongside the river mouth and scolded Touma for leaving her behind after that bold announcement, as well as the fact that he is going after a pregnant woman to which Touma dealt again due to misunderstanding. A great number of sparks appeared along the path of the rubber boat and Misaka Mikoto’s descent. Leivinia held up her wand and Mikoto flicked a coin up with her thumb then destroyed the Muspell before they could attack. They rode the boat and left for Sargasso. On their way, they were attacked by Nidhogg and while they are preparing to counter it, Kagun defeated it. Maria then recognized that it was Kagun and decided to go with him, along with the pregnant woman. Mikoto and the others then continued on to Sargasso wherein they were met by Mokkerkalfe, but it was killed by Thor (Ollerus in disguise). .

They later bear witness to Othinus becoming a perfect Magic God, due in part to the efforts of Ollerus and Fiamma of the Right not knowing that she need only to fail or succeed 100% to unify her infinite possibilities to become a magic god. Moreover, they later see the result of their failure, Othinus summoning Gungnir from her eye socket. They are left behind by Touma as he desperately tries to charge towards her, but all is in vain and the world is later destroyed.

Shifting and Fluctuating World
Prior to Touma accepting that the cruel worlds he is visiting is actually reality, he frequently calls out to his comrades that followed him to Sargasso, Index, Mikoto, Leivinia, and Lessar.

In the second recreation of the world by Othinus, known as the Version_Beta world in-text, where another "Kamijou Touma" exists living Touma's life. She meets "Touma" and Index as they are at the underground department stores since she was there to deal with the owner of a store that has been the sender of junkmail ads to Tokiwadai's dormitory.

In the final recreation of the world by Othinus created specifically to break Touma's spirit, known as the Version_Omega world in-text, where several characters from the original world have been "saved" or have not experienced great tragedy, it is Accelerator instead who saves all 20,000 Sisters, along with Last Order and Misaka Worst after stopping the Level 6 Shift Project. Here, Mikoto and Accelerator have solved both their issues and are first seen accompanying Last Order and a few clones chasing after a paper airplane in the park where Othinus puts Touma in after creating the world. Seeing this, Touma admits that he couldn't save over 10,000 clones, and wishes he realized the events surrounding them sooner that there might've been a different option. He begins blaming himself for accepting that the incident with the Sisters have been resolved. His self-deprecation allows Othinus to continue to break Touma, with him eventually realizing that his very existence and choices may have caused great tragedy to befall people.

After Othinus concedes the world to Touma, she recreates his original world using the Imagine Breaker. The group that went to Sargasso with Touma are back as well, unaware of what had transpired, and are about to face Othinus immediately after her confrontation with Touma in the Black World. With Othinus having lost Gungnir to Touma, she faces her fate in Touma's world. Index calls out to her, telling her that they won't let her get away with what she had done. Mikoto then speaks up, saying she won't hold back after Othinus got her mother involved. Lessar speaks as well, complaining about her and GREMLIN causing chaos. Finally, Leivinia says that she should be crushed right away otherwise she would go hide somewhere and cause problems later. The group later attacks Othinus with Touma still dumbfounded with Othinus' decision to bring him and his world back, causing her to be knocked backwards. Finally, after Touma asks Othinus if she knew of her fate when she saved him, the girls with him are surprised by his outburst. Touma later runs toward Othinus, all the while they try to call towards him. The group later witness Touma defending Othinus from the attack of the Anti-GREMLIN Alliance using magic missiles.
