Memento Mori was a spell tailor made for Zeref. (who is a human mage unless Mashima said otherwise. Immortal, but still a human.) And since that was the case, Gray who was supposedly a demon slayer (If my understanding was right, all slayers had their bodies near the constitution of the ones they slay. Well, that was explained in the first chapter.) had a chance to tank that one. Oh well. Correct me if I'm wrong.

Nice review, by the way.

The 3000 Faces are scattered across the continent (Ishgal), right? I think the next chapter's title would refer to the continent itself. Maybe the aftereffects of Face or another possibly continent-wide magic (Lumen Histoire?).
