Kirito and Asuna investigate the ""Murder in the Area"", which should have been impossible to commit within the game system, only to see a new victim perish right before their eyes.
The common link between Kains and the other victims is the fact that they were all former members of Golden Apple, a now-disbanded guild.
According to former Golden Apple member Schmidt, their deceased leader, Griselda, has become a ghost and is wreaking vengeance on her ex-comrades.
Could something as indefinite as a ghost really exist within this cyberworld?
