Natsu and the others are then brought to Porlyusica, where he remains unconscious. As those around talk about how they cannot treat the mass that's inside him, Natsu's body starts emitting smoke; inside his heart, Natsu is visited by an apparition of Zeref, whom he unsuccessfully tries to attack despite the latter's warning that he cannot be harmed due to where they are. Through Zeref's apparition, Natsu learns of his past before Igneel, when he and Zeref lived with their parents, when he died, and when he was reborn as E.N.D. Zeref's apparition then turns into one of Sting upon Natsu learning that he and the other Dragon Slayers were all friends during their childhood four hundred years ago. Natsu becomes confused at the fact that Sting appeared in Zeref's place, but he explains that his heart erased Zeref and put him in his place. Natsu is then told that if he follows him, he'll learn the true identity of what lurks inside him.
Natsu does just that, but finds that Sting has turned into Rogue (much to his annoyance)
