User blog comment:Besteverunited/Do you guys think that Natsu is the only demon Zeref created or do you think the other dragon slayers were created by him to?/@comment-26460727-20150604090335

When I saw this thread, I believed that yes. it's only Natsu, but something came up inside my mind and I checked this chapter to see if what I remembered is possible. http://www.mangareader.net/fairy-tail/395/18 Check this guys, Torafusa said gajeel's a demon. What if this is foreshadowing? Knowing Mashima, we may never know.
