Misaki Uruchibana was always found in front of a screen, living in another world, a virtual world. When Sword Art Online came out she just had to buy it. Fortunately, Misaki was one of the few chosen to be a beta tester, and convinces her younger sister to step into the world of SAO with her. Kirito and Misaki we're always near each other in the real world, but have never truly met. Until now. The two of them are found fighting for freedom, themselves, and each other.

Once, my name was Aiko. I lived in a normal apartment, had a normal job and had normal friends. Then came Sword Art Online. A game using a new technology called NerveGear which allows players to physically enter the game. After being chosen as one of 1,000 people to become Beta Testers, I played it for months. It was just a game at the time. Then came the official release where another 10,000 people were given access to the game. That was when the logout button disappeared. That was when it became more that just a game. Now I am Amaterasu. Now I am fighting for my life.
