Character

Shirai Kuroko

白井 黒子

Shirai Kuroko is a Level 4 esper and a student of Tokiwadai Middle School, as well as a member of Judgment. She can usually be found accompanying the third-ranked Level 5 esper Misaka Mikoto — her best friend, partner, and roommate. Though a minor character in Toaru Majutsu no Index, she gets a starring role alongside Mikoto in the Toaru Kagaku no Railgun sidestory. Kuroko can be described as a "girl living in the future". She is used to the world 30 years from now portrayed by Academy City and is ignorant to the customs that present-day Japan still practices, like the "love umbrella", which students usually use to link their names to the name of their crush, and the conventional technology outside Academy City. Aside from being a girl with a modernistic outlook, she can also be blunt when giving her opinions, and this has caused her to be at odds with Uiharu once. Another distinguishing characteristic of Kuroko is her feelings of romantic love towards Mikoto. In the ongoing Railgun manga her affections appear to be genuine and that she is truly in love with Mikoto. She even allows herself to get severely hurt in order to do what she can to help Mikoto.[3] She is regarded as Mikoto's best friend.
