Got to say, Natsu had a little development in this chapter accepting his own death and all. Props to him. Let's just hope that Happy, the persona of The Troll, didn't just doom the world and give up their last chance.

This probably means that Zeref won't die in the end since he and Natsu are linked, similar to a Kami and Piccolo relation, except they are brothers and not just split beings. The reason? Because Nalu has to happen. I doubt Mashima is going to sink another Dragneel shipping......is he?
