"Fairy Tail" 487 will most likely see Lady Eileen Belserion release her real power and true identity with the revelation of the third seal.

"Fairy Tail" 486 ushered to several predictions and speculations about what awaits Lady Eileen in "Fairy Tail" 487. Lady Eileen, who otherwise calls herself the Scarlet Angel and refuses the name the Scarlet of Despair, will intuit the looming arrival of the fourth guest. In fact, Lady Eileen will be referring to Acnologia, the Black Winged One. Her façade will speak so much of her sentiments toward the impending arrival and of her thoughts that will include putting an end to Acnologia's life.

Acnologia will reveal himself in his dragon form. Lady Eileen's intentions of killing the Black Winged One give fans the idea that she is in fact the fifth dragon slayer. A follower of the series who goes by the name Dian Glass joined in a forum on Manga Stream wherein she offered to recapitulate what Acnologia said when he killed God Serena, "One down, five more to go." During that period, fans could only identify four dragon slayers namely Natsu, Rogue, Sting and Wendy. With the Scarlet Angel expressing her seemingly eager intentions to kill Acnologia, the followers of Hiro Mashima's manga series have brought forth the theory, and hope, that Lady Eileen might indeed be a dragon slayer herself.

Fans look forward to seeing the Scarlet Angel uncover her true identity and witnessing her strength which will be enough to bring Acnologia to his demise. After all, her character is one of the most interesting and proves to get more fascinating by the minute since she first revealed her presence in chapter 483. Fans speculate that she must be truly strong and powerful should she fulfill her vow to defeat Acnologia, especially considering that even August himself believes that it will be difficult, if not impossible, to go against the Black Winged One and win over him.

It can be noted that in the previous chapter, Lady Eileen asked that Juliet and Hynhe secure the front lines as she gets ready for the coming of Acnologia. Zeref is wondering just as much about Lady Eileen's confidence to beat the fourth guest.

Whether or not this has something to do with the third seal, fans are in for an exciting feat in "Fairy Tail" 487.
