Now that they've made it out of Tartaros's prison, Natsu, Erza, Mira, and Lisanna will start their counterattack against the Nine Demon Gates, and execute a daring raid on the Tartaros guild! Then, as if they don't already have enough problems, Natsu suddenly encounters Zeref the Black Wizard himself! Past the gates of Hell, it's a desperate battle between fairies and demons to decide the fate of the world!
