Mikoto Misaka and her friends are back, investigating rumors across Academy City. Soon, Mikoto discovers something terrifying: horrific experiments are taking place throughout the city, involving the murder of thousands of espers. Moreover, these espers are far from just ordinary people: they are clones of Mikoto herself. Feeling responsible for their treatment, she sets off to put an end to the experiments; however, the forces opposing her are much more dangerous than she anticipated, and Mikoto finds herself up against some of the most powerful espers imaginable.

Toaru Kagaku no Railgun S continues the story of the Railgun as she desperately fights to put an end to the inhuman experiments that she believes she helped cause, her life dragged deep into despair in the process. There's never a dull moment in Academy City, but no one ever said all of them would be pleasant.

So you want to see a review of the latest installment of the raildex universe, To Aru no Kagaku no Railgun S? Then you'll have to make it through this paragraph first.

Second paragraph now. Look around, enjoy yourself, try to find anything of interest. Alas, nothing to note is in sight. Best to carry on to the third paragraph.

Third here, and what's going on? Surely I wouldn't spend 3 entire paragraphs in an attempt to be witty?

Fourth paragraph, and I clearly would.

After enduring that horrible joke, let me save you some time and cut straight to the point. This review will consist of 4 parts: read more

In this world, there are some people who excels in certain things more than others. These might be anything in the field of academics, sports, games, etc. For a particular middle school girl though, she is already know for being a prominent level 5 esper who excels in academics, her electromaster abilities, and is even given the nickname the 'Railgun' for her signature attack. Thus, begins the story of a certain girl, the one and only Misaka Mikoto of the Railgun.

Finally, the series debuted in Spring of 2013. I was waiting for this ever since watching the spinoff of the first season, A Certain Scientific read more

While the second installment of the Railgun series picks up almost directly after the conclusion of the first series, A Certain Scientific Railgun S goes for a different kind of approach thematically and in terms of emotional appeal. Overall, there is a larger focus on the troubles of Misaka Mikoto herself. S1 gave a pretty even amount of screen time to all four of our main characters, so she was not put entirely into the spotlight before, but now she leads this show head on following the events that take place during the sisters arc.

The first episode is what one would expect from watching the read more

To aru Kagaku no Railgun S. A sidestory series which retells the popular “Sisters” arc from To aru Majutsu no Index, though in this iteration it is mostly retold from the perspective of Misaka Mikoto.

The result of this adaptation is mixed to put it favourably. There are times when this anime ascends to brilliance, but there are also sadly many instances where it falls to outright trite. One of the first problems evident is the appallingly slow pacing – the sisters arc takes 16 episodes to tell its story, whereas the original Index adaptation covered it more concisely in 4 episodes. The Index adaptation was read more
