~ Girl in the Dress


The Girl in the dress (ドレスの少女 Doresu no Shōjo) (real name unknown) is the name used to refer to a character introduced in Toaru Majutsu no Index. A teenage girl who participates in "enjo kosai" or compensated dating for money, little is known about her other than she is an operative of SCHOOL and is acquainted with the ways of the Dark Side of Academy City.

She followed Kakine in his plan to steal the Tweezers and in his attack on ITEM, but she refused to go against Accelerator, believing her power would backfire when used on someone with his personality. She was later one of the people from the Dark Side of Academy City gathered to hunt Hamazura Shiage, which left her baffled at how many resources was Academy City using to try to kill a single Level 0.

Notable Attacks/Techniques

  • Measure Heart (心理定規 Shinri Jōgi (Mejā Hāto), lit. "Mind Ruler"): An esper ability of unknown level capable of regulating "the distance between people's hearts", considered a troublesome ability even by a Level 5 like Mugino. It allows her to set herself at a certain "distance in the heart" with a target, allowing her to be either seemingly close in affection to her target or be distant from them. Reactions to this manipulation vary. For example: in one opportunity, she sets her distance to Shiage to the same value he has to Takitsubo Rikou, at which point Shiage is unable to shoot her, the same way he would not shoot Rikou, despite objectively knowing that the Girl in the dress and Rikou are two different people. The Girl also gave a hypothetical example of her power backfiring with Accelerator, stating that he may be the type of person who would feel betrayed when faced with a loved one as an enemy and so would display extreme murderous rage if she used her power on him. This means that she has to be careful on in which level she sets herself when facing a target in order to get beneficial results. Some SCHOOL subordinates also stated she's an esper who can get anyone to spill the beans to her, likely by setting herself to be close to her target so that they trust her enough to tell her their secrets.
