(W) Reki Kawahara (A) Puyocha, Abec Nearly two months have passed since Kirito and Asuna found themselves trapped in the world of Aincrad. Now, they're making their way through the ruins-themed fifth floor, where all sorts of undead monsters-and player-killers-lurk in the shadows! The story of Sword Art Online continues in this brand-new series!

(W) Reki Kawahara (A) Puyocha, Abec The boss of the fifth floor of Sword Art Online will drop the Flag of Valor, a dangerously powerful item set to tip the delicate balance between the guilds! Hoping to preserve parity between the two mightiest guilds, Kirito organizes an impromptu raid to be the first to defeat the boss and seize the flag before it falls into the wrong hands...

(W) Reki Kawahara (A) Puyocha, Abec The fifth-floor boss, Fuscus the Vacant Colossus, brings the raid party to the brink of destruction when it reveals mechanics that are completely different from the game's beta. On top of that, PoH, the leader of Laughing Coffin, attacks Kirito to obtain the Flag of Valor. Will Kirito be able to overcome these unexpected trials and make it out of the fifth floor alive?!
