This is what happens when you don't kill your enemy immediately Mari you hopelessly foolish girl, you reap what you sow.
As for E.N.D., rather than Natsu awakening as E.N.D., this is more like Natsu unlocking his demon powers. Still when Dimaria said it's more than E.N.D. i wonder if this means Natsu has the power of the God Slayer too, considering the fact that he ate Zancrow's flames before and even used it.
The remainder of the chapter was quite redundant, i don't even feel anything towards the Lucy fanservice. That said, anyone think we'll really get a Gray vs Natsu next chapter cause somehow i don't see it happening anymore.
