'Fairy Tail' chapters 512, 513 spoilers: Major dilemma befalls Team Natsu as truth about Zeref and E.N.D. unfolds

The mysteries surrounding Natsu's real identity has gradually been unfolding as the Japanese manga series "Fairy Tail" progresses. Does this mean that the destined and long overdue re-match between him and his brother, Zeref, is drawing near? But how can Natsu hope to win a battle where he dies either way?

"Fairy Tail" chapter 513 titled "Flower Circle" may find Happy at the center of everyone's inquiry after he blurted out the connection between Zeref and Natsu in a moment of grief. The Fairy Tail guild's ultimate mission is to bring Zeref down, and knowing that the dark mage's death could mean Natsu's own demise may present the biggest dilemma that they would have to face.

Happy may be forced to tell the group about Zeref and Natsu's previous encounter in chapter 465, wherein Zeref revealed everything to the skeptical fire mage, including his current identity as one of the dark mage's Etherious demons, who would cease to exist once his creator, Zeref, dies. Zeref gave Natsu that one final chance to defeat him and put an end to his immortal life, but Happy, not wanting to lose his friend, forcibly flew Natsu away from the battlefield.

How will Natsu's team take this game-changing revelation? And now that Gray is awake, will he make an effort to awaken his friend, or will he turn his back away from E.N.D.?

Natsu's journey inside "his heart" also continues and the final answer to the mysteries of his life is about to be revealed. How will this entire journey affect Natsu's disposition when he wakes up? Will he still be Natsu or someone else completely overtaken by E.N.D.? And will Lucy, being a descendant of the celestial mages Anna and Layla, play her own significant role in saving Natsu's life?

There are speculations that the upcoming chapter will also let Natsu in on the relationship between Anna and his friend Lucy, while fans of the manga series are also hoping for answers to the mystery behind Erza and Eileen's striking resemblance. Are Erza and Eileen related in the same way as Anna and Lucy are? And what significance will this revelation bring to the ongoing arc?

A new chapter of "Fairy Tail" comes out in the next issue of the "Weekly Shounen Jump" magazine on Monday, Dec. 5.
