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?

The tournament continues, with part 2 of Book 7. Having overcome Lord Boros, Mikoto now must deal with the potential future that she must leave Fairy Tail forever in order to surely save the Omegaverse. Meanwhile, Mikoto's daughter Miyoko is forced to deal with her potential future fate while Frieza attempts to manipulate her for his own selfish purposes.. At the same time.. Diablo Supreme and Corruption prepare for their final confrontation with Fairy Tail... It all ends here...

This book is Part one of Finale. It's been 10 years since Mikoto returned to life and resumed her duties as a Guild Master and Mother to two, and now.. three. Her children are 11 and she is 26, but still looks like a girl just coming out of her teens (which is probably how she'll remain). Nearly all the members of her guild have started families too, and have seen crazy wild things, just like her. However, the established time has come. The Omega Tournament between the strongest fighters in all of reality is beginning, and Elohim has selected Mikoto and 9 other members of her guild to represent her multiverse. But she knows that the end of the prophecy for the Bane of Diablo also lurks within the legendary competition, and she dreads a future in which she might just have to say goodbye to Fairy Tail.. forever... Will she have to end her days with her beloved guild for the good of humanity? Or is there some other way?

Gol D. Roger, the King of the Pirates, obtained a piece of everything the world had to offer. Before his death, his dying words would drive countless people to the seas. "You want my treasure? You can have it!! Go!! I left everything the World has to offer. " Now.. Monkey D. Luffy, a boy who ate the Gum Gum Fruit and became a rubber man, sets out to find that treasure... or.. it would be that way.. if he weren't scheduled for execution.. Instead, Mikoto Misaka, her friends in Fairy Tail and the rest of the Straw Hats whom have now joined that guild, will set out to rescue Luffy.. or die trying.. What could go wrong!?

Mikoto Misaka , Fairy Tail, and their allies have been flitting around dimensions, searching for the eight eggs of the Imprisoned.. Powerful Dragons born of Dravis's evil. Beating massive foes in different worlds, they finally gather all the eggs in the guildhall and prepare to imprison the eggs in Nebulosos. Meanwhile however, one of the Diablos, Diablo Ezra, is sent by Wrathas to "have some fun" with Fairy Tail. Taking an interest in the 7 Level 5s of Mikoto's era.. Ezra hatches one of the Dragons.. Doppel, the Dragon of Inner Darkness.. The resulting 7 dark followers of Ezra.. bear a striking resemblance, to some familiar faces.. Can Fairy Tail defeat the Dark Level 5s? Or will Mikoto succumb to the darkness in her heart?
