'Fairy Tail' chapter 520 spoilers: Will Natsu choose to be a demon or a dragon?

After focusing on the mother–daughter conflict between Irene and Erza for the past several chapters, it looks like Natsu will once again be the main focus of the Japanese manga "Fairy Tail" with the upcoming release of its 520th chapter.

"Fairy Tail" chapter 519 depicted a dramatic and bittersweet end to the battle between Irene and Erza.

The chapter started with Erza hurling herself towards the falling meteor and successfully destroying it. With the power of Wendy's Dragon Slayer Magic still in her blade, Erza cuts down Irene, which resulted in Irene reverting back to her human form once again.

With Erza incapacitated, Irene — still alive and standing — was about to deal her final blow to her daughter using Erza's own sword. However, before she manages to do so, Erza smiles, bringing back all of Irene's memories with her daughter. Unable to deliver the deadly blow against her own child, Irene chose to end her own life with the use of Erza's sword.

With the conclusion of the battle between mother and daughter, it is high time that fans get to see Natsu in his END form. For the past several chapters, Natsu has been unconscious, wandering through his memories on an "inner journey" to rediscover his true self and save his life.

As reported by Tripped Media, fans last saw Natsu talking to his dragon father, Igneel, in his memories, during which, Igneel explained the true nature of Natsu's power. He also explained how the Demon Seed END, which was planted into him by his brother Zeref, has slowly been eating away the Dragon Seed planted by the Dragon Slayer enchantment.

Once the Demon Seed END fully consumes the Dragon Seed, Natsu will reportedly turn into END. His essence and memories will die away in the process. However, there are speculations that Natsu will get to choose whether he will become a demon or a dragon.

"Fairy Tail" chapter 520 is set to hit the shelves on Tuesday, Feb. 7.
