After bringing Natsu back to the pages of "Fairy Tail" chapter 520, the upcoming chapters 521 and 522 will have the spotlight focusing on Gildarts and Gray once more as it is said that they will be featured battling August and Zeref, respectively, in the next installments of the manga series.

"Fairy Tail" chapter 521 comes with the title "The Strongest Wizard" and is said to have the spotlight back to the fight between Gildarts and August. According to reports, the fight between the two may be a fast-paced one as Gildarts is known for finishing a fight without dilly-dallying. However, as August is not easy to defeat, it remains to be seen if it will really be the case.

Apart from the battle between Gildarts and August, it is also said that the upcoming chapter 521 of "Fairy Tail" will also cast the spotlight anew on Gray as he finally takes on Zeref. However, despite Gray's abilities, some can't help but worry that he might not stand a chance against Zeref, much more that the latter is said not to hold back when it comes to him.

However, if the title of "Fairy Tail" chapter 522, "Gray's Trump Card," is to be the basis, it seems that Gray has something with him (or in him) that can give him an upper hand in his battle with Zeref. Not only does the title suggest that Gray will have an advantage over Zeref, it is also a clear indication that the battle between the two will not readily conclude in "Fairy Tail" chapter 521.

Meanwhile, other sources claim that "Fairy Tail" chapter 521 may be about Acnologia and his backstory. After all, little is known about the said character. As it is believed that every villain has a sad backstory, some suspect that Acnologia's sad past may finally be explored in the upcoming chapter 521, which, incidentally, is coming out today.

Chapter 522, on the other hand, is slated to arrive next week, Feb. 21.
