Fairy Tail Season 9 Episode 18

Across 400 Years

Having survived Natsu's attack, Zeref reveals both his and Natsu's identities as Natsu's brother and E.N.D., respectively; he further reveals that Natsu, Gajeel, Wendy, Rogue, and Sting Eucliffe were sent over 400 years from the past through the Eclipse gate by Lucy's ancestor Anna and Layla as part of the dragons' plan to kill Acnologia. Natsu is skeptical and prepares to kill Zeref, but is stopped by Happy when Zeref warns that Natsu's life is tied to his own, which would result in Natsu dying along with Zeref. After Natsu and Happy retreat, Zeref accepts his own immortality and fully commits himself to his invasion. Meanwhile, Fairy Tail's allies encounter several of the Spriggan 12, with Mermaid Heel and Lamia Scale fighting to free Hargeon from the members Wall, Dimaria Yesta, and Neinhart. In Magnolia, Marin infiltrates Fairy Tail and chokes Brandish for her cruelty towards him. While returning to the guild, Happy discovers that Natsu has fainted.
