Never mess with Gildarts's Porn Collection. He won't take it well. Natsu has improved to the point that he can hold his own against Gildarts.....well better than before at least. He isn't there yet, but I feel that after the 1 year training and a possible END corruption will change that. Hell, I wouldn't be surprised if that is how Mashima plans to take out Gildarts. That would be one way to scale END's power.
