"Fairy Tail" chapter 520 was just released a few days ago, and it has been reported that 521 will be released on February 14, but there are already speculations as to what 522 will be like. Will Gray finally face Zeref in a battle?

MobiPicker reported that chapter 520 was an emotional one when fans witnessed Irene's death. She was on her way to end the life of her daughter, Erza when she started to see flashbacks of the moments they spent together when her daughter was just a little kid. Irene was overcome with emotions and realized she could not possibly kill her own daughter. So to end her suffering, she stabbed herself.

It has been previously said that chapter 521 may feature a backstory for Acnologia. Acnologia was last seen when Irene threw him in the middle of nowhere to borrow time. Fans suggest that a backstory for Acnologia would be reasonable since only bits and pieces are known about him.

Now with "Fairy Tail" chapter 522, Tripped Media said that there are going to be tow high level fights, and it's going to be exciting. Zeref may actually already face Gray in a battle in the guild's HQ. A parallel battle may also happen between Gildarts and August.

Now that Irene is dead, the spell that she has previously cast on Universe One was lifted. Fairy Tail members were transported back to Magnolia, but it's not time to relax just yet, just like what Mavis pointed out. The fiercest battles are yet to come.

Natsu and the other guild members wondered where Gray might have gone. Towards the end of the previous chapter, Gray was shown hurrying back to their HQ only to find Zeref already there. Many say that it would be anti-climactic if Gray manages to defeat the most powerful villain of the storyline. However if Gray loses during the battle, it menas that a  highly anticipated clash between brother is going to happen in "Fairy Tail".
