Making Gildarts the new master is the best thing Hiro could have done considering the 7 years pointless timeskip. Now we have new dragon slayers and Grandine will be talked about. Now that I look at it, prior to the 7 years time skip, it was seven years before even that that the dragons disapeared wasn't it? I take back what I said about the pointless 7 years time skip. If Hiro can pull off a good arc by reintroducing the dragons then regain some of the respect I lost for this series.
“Pirates are evil? The Marines are righteous? These terms have always changed throughout the course of history! Kids who have never seen peace and kids who have never seen war have different values! Those who stand at the top determine what's wrong and what's right! This very place is neutral ground! Justice will prevail, you say? But of course it will! Whoever wins this war becomes justice!”
