After Eugeo's death, and the defeat of Quinella.. Mikoto has become broken in both body and spirit. Sinon in the meantime, is attempting to find a way to contact Haruyuki Arita in the future, who may hold the key to stopping the real world Viros Invasion.. Alice and Kirito in the meantime, fights to protect their broken childhood friend as Yuniko struggles to develop her power and become stronger out of a desire to truly protect her student. In the meantime, Asuna and Accelerator have both logged into the Underworld. Haruyuki in the future along with his friends, fervent to keep his promise to Mikoto, tries to figure out what happened to her and maybe find his friend from the past. The Underworld's story is slowly coming to a close.. and a new story is yet to begin.

Mikoto, Sinon and Kirito have been living in the Underworld for 2 years now. Both Kirito and Mikoto, along with Eugeo, have become Elite Sword Masters each with their own Valet. Kirito has obtained his sword from the Gigas Cedar, the Night Sky Sword, while Mikoto has obtained the River Spirit Sword and dual wields it along with her Master Sword. Sinon in the meantime, has joined the Archery Corps. When Mikoto's Valet, Stella, discovers a dark secret that nearly costs her life, Mikoto and Sinon decide to head out to investigate.. In the process they discover an entire armada of Viros swarming out of a strange portal near the goblin territories. Meanwhile, in the real world, Accelerator and Asuna find themselves in a massive battle against the forces of God's Right Seat and secret forces from the Japanese Government, all of whom seem to be interested in Kazuto, Mikoto, and Shino.. And even stranger still, a dark figure seeks to find the Brain Burst Program, and develop something with it.. The world of Railgun Online is becoming larger still, and there's no telling where it might lead

One bright sunny day, Mikoto Misaka and her cousin Shino Asada decided to meet their friends Kazuto and Asuna at a diner in Academy City. While there, they are attacked by a mysterious magician named Vento of The Front, who gives them a cryptic warning about something called Alicization.. moments after avoiding the attack.. Kirito is assaulted by a former member of Laughing Coffin who took part in the Death Gun incident. In a heated moment, Mikoto jumps in front of Kirito.. taking a needle full of drugs to the chest.. in a frantic attempt to save her, both Kazuto and Shino end up drugged as well.. and Asuna is left frantically calling paramedics as her 3 friends begin to slowly slip away.. A whole new world is then opened up.. a new virtual world.. known as the Underworld..

"I don't do stupid little Fairy Games." That's what Accelerator would say every time Last Order begged him to play Alfheim Online with her. But the truth of the matter was, Accelerator wasn't that kind of gamer. Heck, he didn't even play video games. Then a friend of his Shino Asada, asked him. "What if the game was about steam punk themes and automatic weapons? And what if you get a big fat pay check for playing?" Accelerator then grinned and said. "Well.. sounds a bit too good to be true, what's the catch?" The catch? Well.. it had one name: Death Gun.

Academy City. A city of science, of fact and powers. Here, humans can come to develop supernatural powers of their own and become Espers. Mikoto Misaka is the 3rd most powerful esper.. however, she currently feels powerless to help her friend Asuna, who is still stuck in the virtual world, created by the mad man Kayabe. Along with her friend Touma Kamijou and Kazuto Kirigaya, she plans to go back into the virtual world to rescue her friend.. however, the IRL dangers are multiplying. Powerful espers are taking interest in the world of swords and magic.. and it's creating quite a ruckus.

She woke up one day... in a world she knew nothing of. She woke up not knowing her name, or who she was.. all she knew, was that the world she currently resided in, wasn't real.. Who was she? Was she just a phantasm doomed to haunt a virtual world? A program? Or something more? Was she a player, stuck with a gaming device to her head.. forced to play in this endless death trap? Who was.. she? What was.. the Railgun?

Welcome to... to.. where are we!? That's what Mikoto Misaka, Natsu Dragneel, and Shizuri Mugino are thinking when they wake up in a world they've never before seen. With the crazy and silly Twilight Prankster as their guide, they traverse through a world filled with what appear to be.. ninja.. Disguising themselves within this new world.. they quickly begin their search for the dark diety Corruption, and the main prize himself, Diablo Etwatia.. however, along the way, Mikoto finds herself in a powerful clash with a certain blonde ninja. The battle becomes so incredible, it nearly levels the field upon which it is fought.. who is this person? And why is he such a knuckle head? And things begin to turn even more complicated.. as Mikoto begins to experience strange symptoms.. symptoms that can only mean a certain two bundles of joy are on their way in only one week's time..

It's a bright day in Fiore, Gajeel and Levy have just gotten married.. and while the ceremony takes place, Mikoto begins to think about the future of her relationship with Touma. And the surprises just keep coming when Markarov tells Mikoto he wants her to be the 7th Fairy Tail Guild Master. However.. meanwhile back on the desolate planet of Nebulosos.. The Numensapiens begin to realize that defeating Diablo Etwatia may not be as simple as they have hoped. And to make things even more strange, as Happy to make sure nobody causes trouble on the wedding day, he discovers two young girls by the names of Miyoko and Mirajane Misaka, both claiming to be the daughters of Mikoto and Touma from the future. The threat is not quite gone.. and it seems Urahara might have been building something a little space travel-related in his basement..

It's been 2 months since Mikoto's powers were sealed away.. Mikoto has been confined to a wheelchair.. and it is now the day of her 16th birthday. She has never felt more useless.. and though her friends in Fairy Tail do all they can to try and cheer her up.. there is no escaping the terrible feeling of being powerless to protect her friends.. Then.. six mysterious beings appear in Academy City, calling themselves the Lost Ones. 3 of them, are beings called Quincies... 2 of them are magicians.. and one is a Level 5 esper long forgotten. They seem to have a vested interest in helping to restore Mikoto's lost powers... however, what do they have to gain from helping her? There is something more to this.. and like it or not.. Mikoto has once again sunken into a battle that she might not come out of...

The Final Brawl is here. With the return of the Original Multiverse, Mikoto is now trying desperately to escape Hueco Mundo and return to Academy City, where the final battle is to take place.. Meanwhile, the Gotei 13, Official Guilds, and all manner of magic users, espers, hollows, and Arrancar, have gathered in Academy City for the final battle as Asgawrath in the rage of having his love rejected by Mikoto, moves to strike the Source of Academy City and wipe out planet Earth. As battles rage, and blood rages.. Mikoto's final showdown with Asgawrath draws to a close... but what price will she have to pay for victory?
