It's been a month since Kirito and Asuna returned from the Underworld.

Together again with Alice, who managed to secure a life in the real world, it
should've been happily ever after...But, as luck would have it, the three find
themselves involved in a VRMMO by the name of Unital Ring, and all their stats
have been reset to level one! It's time for Kirito to put his experience to the
test in a genuine Survival MMO!
