**Himegami Aisa** (姫神 秋沙, *Himegami Aisa*?) is a recurring character in *Toaru Majutsu no Index*. She is a Gemstone and possesses the ability "*Deep Blood*," which attracts and kills vampires.

## Etymology

Aisa's family name *Himegami* is an aptronym for her, as it is basically read as the characters (姫 and 髪), meaning *Princess* and *Hair* respectively, referring to the hime cut, a hairstyle that Aisa sports.

## Appearance

Aisa looks like a normal teenage girl. She has long, straight, black hair, and is often seen wearing her miko outfit. After the events of the second volume, she begins wearing a cross necklace given to her by Necessarius so vampires will not be attracted to her blood.

## Personality

She is a quiet young girl with a rather blunt personality, generally soft-spoken and sometimes shy. She can be as gluttonous as Index, which is shown when she was trying to buy out all hamburgers at one restaurant. Because of her ability, she has been miserable because her friends and family were killed by it. Ever since Touma saved her life, Aisa started to have feelings for him, which is ironic as she once joked that Touma's life was like a dating sim.

She also has a kind and considerate side, shown during the Daihaseisai after she was recovering from the near-fatal injury caused by Oriana Thomson, she once thought about leaving Touma and everyone else since she seems to only be a burden to Touma. She thought she didn't have any special talents that could help Touma, nor was she the kind of person that could help others just by her presence like Index. Though Index quickly told her it wasn't true, as Himegami is everyone's friend and a valuable person to everyone who was worth saving.

One of her strongest personality traits is a slight complex about not being special, she can usually be seen reading books with advice on how to rebuild yourself or how to increase your own individuality; Touma once noticed that as she is very talented when cooking she has an important distinctive feature; however, Aisa realizes that such trait is not enough individuality when faced to the unique characters that are around her, such as Tsukuyomi Komoe. Due to the events that have occurred in her past, her initial goal of wanting to be a magician of fairy tales and picture books because she wanted to save those that can't be saved.

Touma also has pointed out that even though she is really quiet, it's not like she doesn't want to express herself, and as such many of the things that she wants to say are showed in some other way even if it's almost impossible to perceive normally, the example that Touma used was that when Himegami is happy she doesn't say anything, but she slightly curls up her lips to show that feeling.

## Background

According to Kamachi Kazuma, he created Aisa as a tragic girl who can never be the female protagonist. That may explain why both in canon and in the fandom, she is barely notable and is the target of constant jokes of her irrelevance.

Known as "Deep Blood," she has the ability to attract and kill vampires. Ten years prior to the start of the series, Aisa lived in a mountain village in Kyoto. Here, a vampire, fearing the power that Aisa held, turned everyone in the village into vampires as a reaction to it. Predictably, they were drawn to her blood and bit, turning to dust. Even the vampire became a victim at some unknown point.

This incident prompts her to go to Academy City, hoping to find a way to get rid of her power and not kill anyone anymore. She arrives in Academy City to find a way to know the secret of her power, and by proxy find the way to remove it. Enrolling in Kirigaoka Girls' Academy, Aisa discovers that even Academy City itself couldn't give her answers. She is later kidnapped by the Cult of Science and taken into Misawa Cram School, imprisoning and apparently abusing her there. Later, Aureolus Izzard later takes over and controls the school, freeing her from imprisonment. Aureolus, looking for a vampire in his plans to save Index agrees to give Aisa a Walking Church which would seal her powers and free her from its burden if she cooperates and help him draw vampires. She agrees and becomes ecstatic that she finally found a shortcut to her dreams.

Because of her exceptionally rare ability, she is enrolled into Kirigaoka Girls' Academy. She later discovers of the apparent existence of Kazakiri Hyouka, who always tops the rankings of the school, but no one has ever saw her, which year she was in or even her powers. Aisa then asks one of her teachers about Kazakiri Hyouka, and discovers that she is called Counter Stop, more importantly, she is called the Key to the Imaginary Number School District, and a special lab was set up just to investigate her. It is later revealed that even the teacher she asked has never seen Hyouka, and that her true identity is known only to a few teachers.

## Chronology

### Toaru Majutsu no Index

#### Deep Blood Arc

*Main article: Deep Blood Arc*
Aisa becomes a major concern to the Magic Side as she has been apparently abducted by Aureolus Izzard, a powerful alchemist who has taken over Misawa Cram School and is an enemy of the Roman Catholic Church. With the situation complicating, Stiyl Magnus is recalled back to Academy City to rescue her. Even though Academy City is unable to intervene with the Magic Side's affairs, Aleister Crowley allows Stiyl to borrow Kamijou Touma's help, as he deems him as no threat to the Magic and Science Side's secrets.

Aisa is first seen in Macronall Hamburger, having spent all her money on hamburgers and unable to go home. Touma and Index meet her, where she tries to borrow money from Touma, but is refused and Index argues with her for claiming to be a magician without proof. She is later escorted by teachers of Misawa Cram School, making Touma suspicious.

Touma later realizes, after being involved by Stiyl, that the person they are trying to save is Aisa. Aisa meets Touma again within the confines of the school and tells her the reason why she joined Aureolus.

When Aureolus learns Index's life was already saved by Touma and tries to kill him, Aisa attempts to defend Touma, which prompts Aureolus to use his alchemy to try to kill her as she is now useless to him. Her life is saved by Touma who dispels the spell on her with his right hand. When she asks Touma about why he saved her, he told her that he did not have a reason to rescue her. After the incident, she starts to live with Touma and Index but later moves to Tsukuyomi Komoe's Tsukuyomi Residence.

#### Sisters Arc

During the Sisters Arc, she is first shown trying to find a way to get rid of the fleas on Sphynx, with her suggesting to use an insecticide spray on the cat. When Touma brings Misaka 10032 to his dormitory, she comments on him being a protagonist of a dating sim, and how he raises flags and inevitably gathers girls around him.

According to Aisa, the vampires are attracted by the sweet scent of her blood, and upon drinking it turns them instantly into ash.

## Character Art Design

### Design Evolution

Due to her standard character design, Haimura had no troubles designing Aisa, though notes that there is an inconsistency in the illustrations regarding the red strings that line the sleeves of Aisa's outfit.

Aisa is affected by Haimura's deformed style change by volume 12, among most characters.
