Fans of "Fairy Tail" expect that chapter 523 is going to be even bigger and more eventful. A very powerful character has re-entered the picture, and it is foreseen that the The Black Dragon Acnologia will cause more havoc than ever.

For the uninformed, "Fairy Tail" is a story about Lucy, a teenager who wants to be a full-fledged mage, Anime News Network said. She meets Natsu, a seemingly ordinary kid, who turns out to be a member for the world's most infamous guilds, Fairy Tail.

According to rumors, fans may be in for a treat as a back-to-back action on the pages of the manga is said to be released. Chapters 522 and 523 are expected to be action-packed, and it would definitely show what's going to happen between Zeref and Gray. Leaks say that Zeref will not hold back as he deals with his brother's friend.

There are a lot of speculations made by "Fairy Tail" fains in Reddit. But there are reports saying that Gray will be using his Trump Card against Zeref, although this may really not be much of an advantage, because it would mean using the Iced Shell, and using the said magic will require him to sacrifice himself. If this is true, then Gray can no longer be resurrected.

Previously, Gray was seen as heavily wounded who found Zeref in the Fairy Tail Guild's building. Zeref apologized to Natsu at the back of his head, and then he stands to face Gray. This only means that Zeref is prepared to fight Gray, no matter what the cost.

Gray's current physical state would prevent him from giving his 100 percent. Meanwhile, the end of the war is drawing near, and the survivors will soon face Acnologia. Now that Universe One is gone and Zeref only has August by his side, Acnologia will return in Magnolia where he was last seen by "Fairy Tail" fans.
