Fairy Tail Season 9 Episode 42

Compassion

While Zeref destroys Larcade and resumes his battle with Natsu, August recovers from Gildarts's attack and begins casting a suicidal spell to vaporize Fiore and everyone in it. Upon noticing Gildarts attempt to protect Cana, however, August ends the spell to spare Mavis, who briefly notices him calling out to her as he disintegrates and dies. Mavis delivers the Book of E.N.D. to Lucy, Happy, and Gray, whom she tasks with using it to prevent Natsu's death before she can kill Zeref. Meanwhile, Jellal protects Erza and Wendy from Acnologia, who reveals himself to be immune to all forms of magic when he devours Jellal's attacks. Ichiya suddenly rams the Christina into Acnologia and rescues the three, telling them about a strategy to defeat Acnologia by luring him to specific location away from Magnolia, and introducing them to a mysterious blonde woman responsible for the plan.
