A Great Event has come to all those who find thrill in VR gaming. The Sci Fi Connect Tournament. A Tournament between the greatest VR Sci Fi games of all time. And there is a prize in this game.. a prize unlike any anybody has ever known. A Sword.. but not just a virtual sword.. no.. The True sword... The True Sword of a Hero from eons long past... The True Master Sword.

Some time after the Death Gun incident, Mikoto and Shino hear about a new VRMMO that's the first SciFi Horror of it's kind, Dead Space Online. It is added as an extension of the GGO server, so those who play GGO are free to play using their avatars, weapons and equipment.. and as a special event, those who complete one of it's 3 main quests, Explore The Sprawl, will receive special rare items for both GGO and ALO accounts. Sinon and Railgun log in to take the challenge.. but instead find themselves unable to handle the extreme horror element of the game in Virtual Reality form. And to top it off.. a problem occurs on the server making players unable to log out for 6 hours until the game masters can figure out the problem. Follow the side story as Sinon and Mikoto bumble hilariously around through hordes of zombified alien monsters

After Mikoto sacrificed herself to save everyone from Zant and his dark master Diablo. Her Fluctlight has been trapped in Zant's place of origin. The game Hyrule Online. Kirito swears to save her, and along with Yui and Midna, they dive into the game in search of her while the 7 Kings of Pure Color finally begin the debate of an alliance, all except for White Cosmos of course. Kirito finds Mikoto.. however, he finds that Mikoto has once more had her memories taken away.. and what is worse, she has been given false ones tricking her into believing that she has lived in HYO all her life as an AI.. Can Kirito bring back Mikoto's memory? Or will she be stuck in a false reality forever?

She awakens.. naked.. afraid.. confused.. within a large transparent pod.. She feels cold.. shivering and wet as the cryogenic sleep wears off.. "K-Kirito?.... S-Sinon..? A-Asuna...? Touma!?" She calls out the names of her friends one by one.. hitting the inside of the pod with her fists. "Anybody!?" She then notices something strange around her neck.. small. not a collar.. as it goes around the back of her neck, not completely around.. using her reflection in the pod.. she reads the brand name.. "Neuro Linker.." She pushes open the door of the pod.. and falls into a desolate looking abandoned lab.. where is she? Or perhaps a more accurate question should be... WHEN is she?

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.

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..

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?

"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.

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.
