'Fairy Tail' chapter 515 spoilers: Irene to reveal more of her past

In the previous chapter, Irene continues to reveal a load of information about her past. She has already shocked Erza by telling her she's her mother, but it looks like she's also "the mother of all Dragon Slayers." Irene revealed that she's the originator of Dragon Slayer Magic and it all started when she asked Belserion to bestow upon her some of his power. So, what's going to happen in next?

Sources note that Irene will continue to reveal her backstory and her connection to Erza in "Fairy Tail" chapter 515. Titled "I Am You... You Are Me," the chapter will allegedly show Erza's birth and it will also tackle Irene's transformation into a dragon.

It is speculated that Irene will notice that the humans are starting to fear her when her dragon scales started to appear. The feeling of being rejected by her allies should hit her hard. That would explain why she seems disgusted by the idea that people would stop loving someone who has become an ugly person.

It is also rumored that she feels guilty that the Dragon Slayer Magic she created has resulted in a lot of deaths, so she decided to turn to Zeref and flee to the Alvarez Empire to join him in hopes of finding Erza. It is said that Irene and Zeref have something in common. Both of them want to die in the hands of someone they love.

Meanwhile, some fans have theorized that Acnologia, the Black Dragon, may be Erza's father, and the upcoming chapter may show Irene meeting Acnologia for the first time.

On the other side of the battlefield, Natsu is still unconscious, but reports suggest his conditions may improve in the upcoming chapter. It is speculated that Mavis may help wake Natsu from his subconscious by creating an image of Lucy to guide him.

"Fairy Tail" chapter 515 is scheduled to come out on Dec. 28 in Japan. In the meantime, readers are advised to take everything with a grain of salt since details for the next chapter are yet to be revealed.
