Natsu vs. Erza

What a battle! Natsu vs. Erza!! The flames of a Dragon Slayer vs. the armored Fairy Queen! Fairy Tail is expecting fireworks; this guild settles things with their fists! Natsu's all fired up and doesn't give an inch to Erza, but just then... A messenger shows up from the council talking about illegal actions during the Eisenwald incident, and he has an arrest warrant for Erza?!
