Prologue

The story we know: An online world, one hundred floors, and permanent death. We know the hero: Kirito, Black Swordsman, Savior of Aincrad. But he wasn't the only one, and his story did not end there. There were others, heroes, villains, crooks, and the ones in between; they not only fought, they lived, they loved, and they survived. This is the journey of the untold, the ones whose stories were left behind.
