In Academy City, a scientist appears and has been taking people for his own sick experiment over the years, but then his eyes are set on a certain level 0 that was able to defeat Accelerator named Kamijou Touma. Rewrite in progress.

A middle schooler girl name Misaka Mikoto who was one of the 7 level 5 espers .... A girl who uses electricity but can also control lightning. Mikoto is a tomboyish girl who study in a girl-school-only... And the people around her in the school call her 'Ace of Tokiwadai' because she is rank 3rd in the seven level fives...But sometimes they call her 'Misaka-sama , Misaka-san' etc. A high schooler boy named Kamijo Touma is an level 0 ...It means that he don't have any powers... But he possesses a thing that no one can describe. They called it Imagine Breaker.... they cannot describe it if it is magic or science.. That is why it is really a big mystery. The two of them always fight when they met each other. Probably Mikoto is the one who will start it. Will they have chance to love each other? or Is it just like always?......... Now what will happen if the story was change?...Let see......?

"Ask anything you want from Onee-sama or to Savior anything will be okay!!!!" says Misaka cheerfully.

Think that confessing your love to a dense boy or a dishonest girl is easy? Think again! Because the dense Kamijou Touma and the dishonest Misaka Mikoto will show you how hard is to confess their love to one another.

Based on the anime series "A Certain Magical Index/IndexII" and "A Certain Scientific Railgun/Railgun S" you should watch them, they are well made both plot-wise and animation-wise
