To Aru Kagaku no Railgun

The story is set in a world where supernatural powers exist through science, and magic exists through religion.
‘Academy City.’ 2.3 million inhabitants.
80% of the students are active in the ‘Brain Development Program’ and out of those only 7 are Level 5s.
Diverging from the plot of Index, Toaru Kagaku no Railgun focuses more on Academy City and the third of seven Level 5 espers named Misaka Mikoto.
Misaka Mikoto, despite being part of the most powerful espers in Academy City, also has a more carefree side to her life. She has to fend off constant “love attacks“ from devoted friend and roommate Shirai Kuroko and she needs to maintain the image of being perfect as the Ace of Tokiwadai Middle School.
However, with various problems arising in Academy City — both noticeable and out from plain sight — she moves as Academy City’s unseen savior, using her powers to save people, loved ones and strangers alike.
