Interesting chapter. For everyone who hates Eileen... sorry guys. Eileen went from a character who was pulled out of nowhere to the inventor of Dragon Slayer magic. That was surprising and I suppose some people are going to be pretty mad about this.
So... who is Erza's father? Eileen has Belserion's name but it doesn't seem like he's the father. Who knows though? On a side note, Erza really is Eileen's biological daughter. That's good to know.
Also, I can't believe Lucy is actually naked on top of Natsu. I mean, seriously? We don't need fanart anymore, do we? So Mashima, if you're going to go this far, can we get some scenes like this for the other pairings? That would be fun. :P
