Profile at a Glance
Kuroko Shirai is a 12–13 year-old Level 4 Esper attending Tokiwadai Middle School, known for her role as a protagonist in Toaru Kagaku no Railgun. She is affiliated with Judgment, a special organization tasked with maintaining peace in Academy City. Kuroko possesses the ability of teleportation, enabling her to instantaneously move herself and objects within a limit of approximately 137 kilograms.
Personality & Motivations
Kuroko is characterized by her strong devotion to her friend and crush, Mikoto Misaka, whom she affectionately refers to as "Onee-sama" (big sister). This infatuation manifests into an unhealthy obsession, leading her to seek moments of physical intimacy with Mikoto, often resulting in feelings of jealousy when Mikoto pays attention to others, notably Tōma Kamijou. Despite her provocative behavior and self-proclaimed perversion, Kuroko shows deep loyalty and courage, particularly when it comes to protecting Mikoto. She is often seen as a spirited, energetic character, well known for her cheeky remarks and playful attitude.
Abilities / Powers
Kuroko’s primary ability is teleportation, which allows her to move instantly to a location within an 81-85 meter radius as long as the total weight of herself and any objects she is carrying does not exceed 137 kilograms. Kuroko typically utilizes a unique strap of needles that she can teleport, which serves as a means to immobilize her enemies. One major limitation of her power is that any distraction can disrupt her concentration, making her abilities ineffective. Furthermore, her teleportation must be targeted; she cannot teleport arbitrarily without a clear mental image of the destination.

A pivotal moment occurs during the Tree Remnant arc, where her feelings for Mikoto are put to the test when she risks her own well-being to help her friend.

Throughout the Railgun series, Kuroko gradually develops from a character primarily defined by her infatuation to one who possesses a better understanding of friendships and personal sacrifices.

Firstly, her bond with Mikoto Misaka is central to her character identity, serving not just as a storyline but also as a driving motivation for her actions.
