Zeref reveals himself as Natsu's brother, telling him that he is E.N.D. and the 400-year plan (Zeref, Igneel, Heartfilia family) against Acnologia. Natsu attacks, but Happy stops him: Zeref's death will kill Natsu. Brandish (imprisoned) tries to kill Lucy to avenge her mother Grammi, supposedly killed by Layla for the Aquarius key. Aquarius returns with her restored key, revealing that Zoldyck killed Grammi, clearing Layla's name. Happy brings the unconscious Natsu back. Porlyusica diagnoses a tumor (magical overload against Zeref). Brandish reduces the tumor. God Serena defeats his peers, the Wizard Saints, and is killed by Acnologia. Erza defends Hargeon, and Laxus destroys the Wall.
