In A Certain Scientific Railgun, we follow Mikasa, a level 5 esper who controls electricity. Together with Kuroko, a Level 4 teleporting esper, they attend the prestigious Tokiwadai Middle School. Despite being one of the strongest in Academy City, she is acquainted with quite a few level 0 characters. These includes Ruiko and Uihara in her clique, and Touma as a love interest.
