It’s been one month since the players have been locked in the game. 2000 people have died; the first floor hasn’t been cleared yet.

Something isn’t right; Recon has sent Leafa a message “I was right. Be careful. S." What does he mean and will Leafa and Kirito have the time to figure it out?

Kirigaya Kazuto has beaten death twice but there is one more thing he must do.

Kirito decides that Death Gun and the man in the cape will be appearing in BoB. He uses the remaining time to exchange information with Sinon and find out more about the contestants.

The main BoB tournament begins and 30 players are dropped in a 10km wide field.

Kirito and the others are tasked with subjugating the Frost King Thrymr, and a quest to recover Excalibur. It's Yui's guess that this isn't a quest planned by the game admins, but something automatically generated by the system. And if that's the case…

Kirito and the others are taking on Thrymr, the Boss lurking at the bottom level of the dungeon. But unable to make much of a dent in Thrymr's HP, they soon find themselves in grave danger. Just then, their new ally, Freyja, raises her voice…
