The saga of Sword Art Online continues with three side stories set during the Aincrad and Alfheim eras.

After numerous setbacks, she finds herself without friends or equipment, and only a few "Thirst Points" left to her name. Backed against a wall, she'll need to defeat a terrifying boss monster to survive. Meanwhile, Kirito's group splits in order to both search for Shinon and defend their home, unaware that a mysterious assailant lies in wait...

Kirito and Sinon's battle with Death Gun is over, but mere weeks later, something strange is afoot in the next-generation VRMMO ALfheim Online.
