Fairy Tail Season 9 Episode 46

Raging Fire of the Dragon

Realizing that Lucy is being burned from the inside by Natsu's demonic flames, Gray uses his ice magic to help her resist and find the page containing E.N.D.'s essence. In a final clash with Zeref, Natsu intensifies his flames until he is able to burn away Zeref's magic and defeat him, leaving him immobile but alive. Exhausted, Natsu bids his brother farewell and leaves the guildhall as Mavis regains consciousness and confronts Zeref before he can recover. Meanwhile, Jellal's attack on Acnologia fails, and he is nearly crushed to death in Acnologia's hand. While everyone else falls overboard into the ocean, Anna and Ichiya steer the Christina into Acnologia and push him into the time rift, saving Jellal and sacrificing themselves as they and Acnologia vanish with the rift.
