With the conclusion of "Fairy Tail" chapter 512, it is finally revealed to the Fairy Tail guild members that Natsu will die along with Zeref. On the other hand, Sting was finally able to defeat Rahkeid with the help of Rogue and Kagura's abilities. Now, readers are looking forward to what will happen in "Fairy Tail" chapter 513.
Hiro Mashima never fails to excite his readers with cliffhanger endings, and more revelations in the plot. Based on "Fairy Tail" chapter 512, many readers speculate that Anna is related to Lucy - which could be true because Anna is a celestial spirit mage who is a member of the Heartfilia clan. It was also revealed that she was the previous owner of the Gate of the Water Bearer Key, which summons the Water Bearer, Aquarius. It is obvious that in the coming chapters, probably in "Fairy Tail" chapter 513, readers will finally know the relationship between Anna, and Natsu.
"Fairy Tail" chapter 513 might talk more about the relationship of Anna to Natsu and the dragon Igneel, whom Natsu referred to as his father. It was revealed in the previous chapter that Anna was the person who knitted Natsu's scarf and even Zeref described her as "a kindhearted person who was especially gifted at taking care of others." Many readers speculate that there is a special relationship between Lucy and Natsu because of this.
Meanwhile, with Happy's revelation that Natsu and Zeref are related and that when Zeref dies, so will Natsu, "Fairy Tail" guild members are in a dilemma. Grey Fullbuster, who expressed a great deal of hatred to Zeref and E.N.D appeared to be in deep thought in the last panel of "Fairy Tail" chapter 512. In "Fairy Tail" chapter 513, readers might be able to read the guild's decision to whether they will sacrifice Natsu to kill Zeref. Aside from that, there could also be a lot of things to be revealed between Erza, and her current enemy Irene.
Rumors have it that "Fairy Tail" will soon be ending, but "Fairy Tail" chapter 513 does not answer questions about the great dragon, Acnologia, so an ending might still be a long ways to go. A great plot twist would be if Zeref and his gang with "Fairy Tail" and the other guilds will work together in order to defeat one great, and humungous enemy, which is Acnologia.
