Appearance[edit | edit source]
She is a tall woman that has glamorous proportions, and is always seen with a green jersey, which hugs tightly on her large bust. Her long hair is tied into a ponytail, making her look careless, but also gives her an intriguing sexy feeling.
Personality[edit | edit source]
She has a kind and caring nature, that extends to her job as Anti-Skill, and is most especially apparent with children, which she has promised to herself never to turn a weapon on them. However, her love more or less encompasses violence that an old generation P.E. teacher like her will execute.
She takes her job seriously, and often berates her junior, Tessou Tsuzuri if she doesn't do her job properly on patrols. Due to her habit of ramming delinquents with protective items like shield or helmets to resolve incidents, saying it's alright to do so since those are protective items, she's known as 'The woman who makes the serious comical'.
Out of the job, she is very cheerful, and enjoys beer, eatouts, and public baths with her friends, apparently, willing to go become pass-out drunk in public. She also enjoys teasing Tsukuyomi Komoe as if she was a child. She also believes that there is no shame in showing her naked body to teenagers like Accelerator since they are still children. This was shown when he walked in on her, Last Order and Yoshikawa Kikyou showering, they didn't feel embarrassed one bit and acted casual about it since they believed that he was still a child and that they were adults and it was okay. She also has a tendency of going on a cleaning spree when upset which ends up in making her do reckless things like losing her keys.
Background[edit | edit source]
Not much known about her past, but it has been shown that she is good friends with Yoshikawa Kikyou, to the point that she can ask Aiho to take care of two children for her, as well as take her in. It is implied that Aiho has done something terrible for her to warrant not to use a weapon at a child even if they were espers, but it is unknown what had happened.
She took the test to join Anti-Skill at the same time as the Tokiwadai Dorm Supervisor, but both ended up failing to complete the test by beating up all the instructors. While Yomikawa managed to pass by apologizing, the dorm supervisor gave up on joining, both due to being disappointed in the instructors and because she thought herself more suited to protect a single place she lives in instead of the entire city.
At some point before the series began, Aiho and her team dismantled the Special Ability Institute, the place where Accelerator was in until he was nine. Yomikawa Aiho lives in Family Side and is a teacher in A Certain High School, where she teaches a class full of elites, which is just next door to Komoe's class.

There, Accelerator wants to confirm if Aiho is determined to take them into custody, considering his contact with the dark side of Academy City. Aiho proudly tells him that her job will keep her safe at best.

Accelerator does not seem to understand what Aiho tries to point out at first, but soon, Aiho clarifies things; she thinks that Accelerator is still fearful of returning his goodwill he receives from Last Order. Aiho then recalls on his past, as part of the experiments of the Special Ability Holders Multiple Alteration Technologies Research Institute. He has accepted that fact that he was a monster since his days in the said facility, and because of this, he thinks that he is no longer able to show goodwill to people.

- Main article: Dream Ranker Arc
She made a brief appearance in Yoshikawa Kikyou's dream (experienced by Misaka Mikoto through Indian Poker), where Yoshikawa compared herself (who had measured no bust growth since her teens) to her and wondered if her breasts were her true form.
The proliferation of Indian Poker led to information previously restricted to School Garden leaking outside, with the nature of the card's production complicating the schools' efforts to prevent information leaks. After toys used to make the card dispenser were recalled by their manufacturers, likely under pressure from School Garden, an alternative design using different toys was uploaded. Yomikawa and Tessou were among the Anti-Skill members attempting to find the uploader, without success.
Toaru Kagaku no Accelerator[edit | edit source]
Yomikawa's team responded to a break-in at the Atmospheric Continuum Mechanics Research Facility, with Yomikawa wondering what they could be after given the facility's apparent purpose, arriving too late to stop the thieves who cut through the floor and escaping underground. Later that day, having learnt that the stolen equipment was a weapon intended for use against Accelerator, Yomikawa's team went to Heaven Canceller's Hospital where Accelerator was being treated after being shot in the head, as that was where the thieves were likely to strike next. They subsequently fought the trio of thieves when they came looking for Accelerator, hoping to obtain a sample of his genetic information.
Necromancer Arc[edit | edit source]
- Main article: Necromancer Arc
Yomikawa met with Accelerator after his battle with the Prototype Coffin outside Heaven Canceller's Hospital. Learning about the group posing as Anti-Skill and their ability-using weapon, Yomikawa confirmed that the corpse inside the Coffin was that of Hitokawa Hasami, who had apparently committed suicide several days prior by jumping off a bridge into a river but whose body was never found, as well as the fact that she was a Level 2, with both Yomikawa and Accelerator noting the discrepancy with the Level 4-class damage which had been caused by the Coffin.
After another incident at the hospital, Yomikawa carried out an investigation into DA and found a large amount of files on the organization which had not been accessible before (with the high-level backer who had previously kept them from Anti-Skill having withdrawn his support), detailing its equipment and personnel. Recognizing many disgraced Anti-Skill members among the line-up, Yomikawa thought that it was as if the darkness of Anti-Skill had gathered in one place. She was then alerted to an explosion at School District 3's warehouse area, one of the locations used by DA.
Yomikawa was among the Anti-Skill teams sent to crush DA. During the battle, she noticed several DA members trying to escape with a black bag. With assistance from her colleague, Yomikawa leapt up to intercept them and was enraged at seeing signs that the bag contained a person. During the subsequent struggle, she was shocked to learn that the bag contained a girl who looked like Misaka Mikoto. She also witnessed the carnage wrought by the Tarantula and the arrival of Scavenger.
The damage from the clash between the two caused the level Yomikawa was on to partially collapse. She unsuccessfully attempted to prevent the Sister from falling but Esther Rosenthal and Huotou arrived in time to save her. Though surprised at seeing the late Hitokawa Hasami up and about, she stood with the two to protect Misaka 10046 from Scavenger, who were keen to kill a teacher such as herself, but was knocked out early on in the battle.
In the manga, Yomikawa regained consciousness as the wounded from the battle were being treated, with initial first aid having been carried out by Esther, who had departed after letting the reinforcements know their whereabouts but before their arrival. In the anime, she and Misaka 10046 regained consciousness shortly before the arrival of the Coffins and the latter's abduction.
After contacting her colleagues, she received a brief explanation from Esther about Hitokawa Hasami's current state, the necromancy being used with her and in the Coffins made by Hishigata Mikihiko, and the danger posed by the Evil Spirits of the Numbers, before Esther and Huotou left to help resolve the incident. She was subsequently involved in the battle against the remaining members of DA at Seiin High School and witnessed the events which unfolded there.
After the incident's conclusion, Yomikawa visited Accelerator in hospital, hoping to learn more about what had transpired since he was there. When she arrived, she passed Last Order as she went out on an apparent errand, briefly wondering about her but not saying anything. She apologized to Accelerator for the trouble that they had caused him, adding that he did rid Anti-Skill of some scum, before asking him about the incident. She was not particularly satisfied with Accelerator's answer, but with Last Order having run back and making a fuss after realizing she had been fooled, Yomikawa decided it would be better to come back some other time and left, taking Last Order with her.
Nectar Arc[edit | edit source]

Last Order visited Yomikawa at work to inquire about Himegi Matsuri after she apparently disappeared after leaving the hospital with a group from Anti-Skill a couple of days previously. Although initially reluctant to divulge information due to the risk of someone listening in, having dragged Last Order into a private room when she first said the name, she eventually told Last Order that Himegi was a person of interest in a case and was being pursued by an organization from the Dark Side of Academy City, confirming her safety but not allowing Last Order to see her.
Following Himegi Matsuri's abduction by Full Course, Yomikawa questioned the injured Tobio Yumi, learning about the circumstances surrounding her sibling Tobio Mami, who had disappeared after an apparent abduction under the pretext of treatment for her illness but resurfaced in Full Course's service. Learning that a member of the Board of Directors was involved in the case, Yomikawa decided to secretly take action on her own, managing to get aboard the Escoffier and encountering Accelerator again along the way.

Shiage lets their station wagon slide as so not to lose control. After he regains control of the vehicle he speeds off again. They later see that she has passed off the vehicle as an Anti-Skill vehicle by attaching red lights on top and uses a megaphone to ordering them to stop.
Hanzou tries to shoot at her, but she uses the truck to pin the station wagon on a guard rail. As it could not handle the force, the rail breaks apart with the station wagon and transport vehicle, sending them into an uninhabited warehouse. After striking the inner wall of the warehouse, the truck becomes stuck and couldn't move anymore. Aiho is later given a three-shot at by Hanzou, who says that it is powerful and cool to fire a bunch of bullets at once. Hearing their argument, Aiho determines that her opponents are all idiots. Suddenly, either due to the crash, the gunshots, or both, the truck's transport of soccer ball-sized fireworks falls out all over the warehouse. Moreover, Hanzou's haphazard firing had hit some sort of electrical wire which in turn has come into contact with some leaking gasoline from the truck. Seeing this, Aiho flees.
This was apparently all set-up by Shiage, who had Hanzou fire at the truck's fuel tank. The three then find that Aiho is running away, to which Shiage says that he wants to capture her and show her up. Ritoku responds that they will do no sexual crimes, though Shiage says he knows and changes the subject to the ATM. As Shiage tries to go back to the station wagon, something hit his toes. Much to their horror, they find one of the soccer ball-sized fireworks spheres on the ground and that the truck they hit is from Fukuoka Fireworks Manufacturing. With a flash from the electric wires that has been severed, the fireworks explode. Aiho later comes and arrest the three after escaping the explosion.
The Second Friday of June[edit | edit source]
Aiho is apparently with Uiharu Kazari in an open café. Being too lazy to submit her report to school in person, she asks a waitress if there is a wireless LAN in the establishment as she wants to send it through the Internet instead. Her willingness to use an use the wireless LAN without countermeasures earns the contempt of Kuyama Kihan, calling her an amateur for being a casual user of computers.
She is working on her report while Kazari, the Goalkeeper, is challenged by Kihan in the same establishment. It is unknown what Aiho did afterwards, but it is likely she bears witness to Kihan being apprehended by Anti-Skill after Kazari reports his location. She is likely left behind as she works on her report after Kazari leaves.

Quotes[edit | edit source]
- (To Accelerator in Index II Episode 17) "Just listen to yourself. Despite all you're saying, you're trying to point out the risks your guardian is taking. That means you are ready to protect us."
- (To Accelerator in Index II Episode 18) "This is a rule I made for myself: I will never point a weapon at a child. Even if they're an esper. Do you know why?... That's exactly it. It's probably nothing compared to what you have to face. But the fact that we're heavily indebted to others is the same. So no matter how painful it is, there's no choice but to pay back as much as possible. And unlike me, if you have strength. There are many doors open to you."
- (To Elder Sister in Railgun Episode 14) "How about surpassing your limits? Look at that guy. He was the first to raise his hand, but he's still running. The instant you say you're done and give up, it's over. You might have power in you that you aren't aware of yet. And her. She thought she was done too, but she ran another lap. Where did the power to run that lap come from? It's the same with ability development. If you decide your own limits yourself, it's over."
- (To Accelerator in Index Volume 15) "It doesn’t matter whether you are a Villain or Hero, Accelerator, nor is what kind of world that you are involved in. For me, what’s most important is bringing you back. No matter how dark or cold your world is, I’ll never give you up, and drag you back!"
- (To Anti-Skills regarding Accelerator in Index Volume 15) "'Do you know who it is standing there?! That is a child that we must protect! Pointing guns at children, I’ll never agree! How could I possibly agree to something like this!!” -- Said in Vol15 to prevent Anti-Skills attacking Accelerator.
- (To Hamazura Shiage, Komaba Ritoku, and Hattori Hanzou in Index Volume SS2) "U-umm.. This is Yomikawa Aiho of Anti-Skill Branch 73. With charges of theft, property damage, attempted murder, and interference with a public servant's duties, I'm taking you pieces of shit down to Hell!!"
