Shirai Kuroko
Besides, the idea of superpowers hurting others, really, there’s not much ambition to it. Before a collapsed bridge is repaired, I can use my powers to help others to cross the river. If there are people trapped in the underground mall, I can help them escape to the surface. If the use is correct, what’s so bad about using esper powers? To me, those dreamy words of yours are way beyond lame. Scared of your power? You don’t want to hurt others so you don’t want the power? It’s nice when you say it, but who was the one who hurt me to such an extent? If you want to know whether your actions are correct, just look at my wounds! This is the answer!
~ Kuroko Shirai to Musujime Awaki


Kuroko Shirai is a resident of Academy City, a student of the prestigious Tokiwadai Middle School and the roommate of the #3 Level 5 Misaka Mikoto. Despite her obsession and devotion towards Mikoto, Kuroko is actually a member of Judgement, Academy City's student-based disciplinary committee that helps Anti-Skill keep peace in the city. She takes her job very seriously and honestly desires to help and save people with her esper power. Kuroko is a Level 4 teleporter who combines her teleportation ability and her martial arts skills to deal with criminals.

Kuroko is a minor character in the main novels. She takes a more important supporting role in the Toaru Kagaku no Railgun manga and related side stories, though she has been a protagonist in one of the Index novels, where she faces another Level 4 teleporter Musujime Awaki.

Notable Attacks/Techniques

  • Teleport (空間移動 Kūkan Idō (Tereporto), lit. "Spatial Movement"): Kuroko is a Level 4 Teleport esper. Her ability allows her to teleport herself and/or anything she's touching a certain distance from her position. Like all teleporters, the theory behind her teleportation is to get away from the 3 dimensions, find their position in the 11th dimension, and then calculate the vectors to teleport. If an object is teleported inside another it will displace any matter upon its arrival, allowing teleporters to do things like cut the support pillars of a building by teleporting glass panels inside them. She can teleport up to a maximum of 130.7 kilograms to a distance of 81.5 meters from herself. Kuroko's combat style is based on teleporting the steel needles she carries in her thigh belts inside the opponent's body or uses them to nail the opponent to the ground and immobilize them, though she has also used them to damage an enemy's weapon. She's also adept at teleporting herself around the enemy to attack from their blind spots or teleporting the enemy at different angles without moving them past a few cm, effectively turning their bodies upside down so they fall on their heads or to make them face another direction. Since teleportation is a point-to-point movement there's no inertia to it, allowing her to travel long distances at about 288 km/h with consecutive teleports and stop instantly without any issues. Like other Teleport espers, Kuroko cannot teleport other espers with the same type of power.
  • Martial Arts: Kuroko is a very skilled martial artist, which she combines with her esper power to subdue larger and stronger opponents with ease. Her style emphasizes throws and take-downs, though she also seems fond of kicks.
  • Judgement Tools: Besides her steel needles, Kuroko carries several tools for her Judgement work.
    • Gloves
    • Handcuffs: Special non-metallic handcuffs used by Judgement.
    • First Aid Tools: Including a toothpaste-like soft tube that holds a past-like first-aid medication that is applied to wounds. Developed by Heaven Canceller, the medication has the ability to disinfect, clot blood and heal the wound, being able to treat most external wounds.
    • Detection Tool: Judgement members are equipped with a simple detection tool. The tool is connected to the lower connector on their phone to act as a sensor and put together data on the composition of the air and whether there are harmful electromagnetic waves nearby.
    • Detective Tools: Simple devices to check for fingerprints and similar things.
    • Flare Gun: A flare gun used by Academy City's security forces to indicate nearby civilians that there's going to be a fight in the area, acting as an evacuation order.
    • Jamming Devices: Kuroko carries several small ball-shaped handheld devices made to interfere with listening devices for security purposes. She has used them to deafen the echolocation of Mitori's Liquid Shadow puppet.
