User blog:Solstice962/Lucy is the one thing that can defeat E.N.D

-If Natsu is a demon, then it only makes sense that the one thing that could end him would be an angel. Which in the Fairy Tail world, would be a person who is the closest in touch with the heavens, meaning a celestial wizard... meaning Lucy. thus, Lucy is the only one who can kill Natsu...-

First, I would like to admit that this is not an original theory! All credit goes to the rightful owner. I just felt that this theory should be shared. And just putting it out there, if a dragon slayer who has used their magic their entire life can't kill a dragon, then why would Gray be able to use demon slayer magic to kill a demon, when he has next to no experience...?
