Zeref is gone, and Acnologia is now trapped inside a rift in time. Just when it seems like it's time to celebrate, an ominous crack appears in the sky. What's more, all of the Dragon Slayers suddenly vanish into thin air. The battle isn't over just yet.

Lucy's plan for stopping Acnologia's physical form is immediately ruined, but everyone comes together to keep hope alive. Inside the time rift, Natsu and the other Dragon Slayers face the spirit form of Acnologia in an epic seven-against-one battle.
