"Fairy Tail" chapter 519 has finally put an end to the battle between Irene and Erza. Irene killed herself using her daughter's sword, even if she had the chance to kill Erza. She used the sword to stab herself after seeing Erza smile at her when she was about to kill herself.

Now, "Fairy Tail" is ready to move to a new chapter, after dedicating an entire chapter to the mother and daughter duel. Fans will witness Natsu back to the spotlight during chapter 520, and they will also see him decide between the demon seed planted by Zeref in him or the dragon seed.

But Natsu replied that he wanted to be human. The dragon did approve Natsu's choice and it allowed him to finally wake up. When he did, he found himself in the midst of a half-naked Lucy and Happy, ASZ News said. After asking about how everyone is doing, he felt the place shaking up. It was then revealed that after Eileen's death, the place returned to its original state.

Chapter 521 may feature the return of the main villain Acnologia, Tripped Media said. The last time Acnologia was seen was when Irene Belserion threw him in the middle of nowhere to borrow time. Irene managed to impress the villain using her powers but will it be enough to actually defeat Acnologia?

"Fairy Tail" fans suggest a backstory for Acnologia. Only bits and pieces are known about him, like he did proclaim himself as King Of All Dragons. Another thing known about him is that he is someone looking for a worthy opponent. He also killed both dragons and humans before.

But why is there a striking resemblance between Acnologia and Natsu? The similarity in character design is rumored to be a major plot twist. This similarity was revealed when Natsu sported a long hair after his one-year training. If there is a connection, it could be a mind blowing twist, fans agree.
