Usamimi

Usamimi (ウサミミ) is an original character introduced for the mobile game Toaru Majutsu no Index Struggle Battle. As her name indicates, she is a girl who apparently wears bunny ears on top of her head, and demands to be called Usamimi to the player. She is the tutor of the game, introducing the game mechanics to the player.

Etymology
Her name means rabbit ears, referencing her head gear.

Appearance
Despite her name, she can be seen as having a vicious face. She wears a pink bunny ears, which apparently moves, and a bunny badge upon her loose and unfitting white jacket, which she wears over a dress of black and yellow, with a high hemline that exposes her thighs and legs, and wears pink bunny slippers. She has purple hair with a gray streak running down the fringes of the left side of her face, and ends upon her shoulders. The color of her eyes are red and blue.

Due to her appearance, she can be assumed to be a child, most likely younger than Uiharu Kazari, this is just mere speculation.

Personality
As indicated by her nature, she is apparently a very haughty person. She seems to like rabbit-themed things and wear them. She also covets Gekota and Pyonko goods, similar to Misaka Mikoto. Her every day is behavior does not suit her way of talking and appearance. She is into the rabbit costume to the point where she doesn't care if she is incovenienced by it, as evidenced by her wearing the rabbit themed Santa Claus costume.

Although she is in active pursuit of interesting things, she doesn't as easily become involved with them, like aiding feeding Index, though she actively supports the player in enhancing their abilities for the sake of battling powerful magicians and espers. However, as far as her own behavior is concerned, her help is passive and simplistic, using criticism as an aid, saying, "a helping hand is only held out to those who are incompetent."

She refers to herself as Usamimi, and her real name is unknown.

In the beginning of the story, she speaks like what one would expect from a scientist. She has a peculiar way of laughing.

Background
She is seemingly a scientist of Academy City, as she provides the player with Boosters, which she has invented, for their Illusory Partial Portrait (Imagine Shadow), has high performance smokescreens, can seach for people using GPS apps and network security cameras in the city, and has deep knowledge of technology of the Science side.

Moreover, she seems to have no more on hacking surveillance cameras and stealing information, and readily does it if she desires. She is also apparently acquainted with the dark side of Academy City, knowing of Musujime Awaki, Komaba Ritoku, as well as the Sisters. Suprisingly, she also understands the "other" side, magic side, knowing of the "Empy Area", can gauge a magician's response by some means, the affiliations and combat styles of Agnese Sanctis and Stiyl Magnus, is informed of Kanzaki Kaori's peculiarity as a Saint, and can identify Sherry Cromwell, just by looking at the type of magic she uses. However, on the other hand, she is unconcerned of Index, and doubts the existence of Santa Claus, making her not all that knowledgable of the magic side.

Once again, with the science side, she is aware that Index is living with Kamijou Touma, but unaware that students live in dormitories, making it seem that she only knows odd information.

The player first meets her in a public park in Academy City, after a mysterious girl's voice calls out to protect him from deliquents.

Also, the magic side has dispatched magicians like Stiyl and the Agnese Force as well as prisoners like Oriana Thomson to Academy City in order to target her.

In the game, she approaches the Player and has the Player use Imagine Shadow to help her acquire supernatural powers of both psychic and magical nature.For that reason, she is deemed to be in violation of the pact and has many assassins from both sides sent after her. As a countermeasure, she carries out a strategy to take both the Player and Last Order hostage. However, the Player refuses to go along with it and engages her in battle. She uses some kind of method to apply pain to the Player so that she can use the Player as her servant. After that, she makes an effort to contact the darkness of Academy City in order to oppose the assassins.
