This was an okay chapter, it is a breather chapter and I think we needed one. The chapter does live up to the name pain.
Natsu should have no trouble with these guys, he is suppose to defeat the big boss E.N.D. or he is E.N.D. either way he shouldn't have trouble with these guys.
I thought the Lucy / Juvia moment was nice, Juvia in her mind consider Lucy her rival, so putting that aside for a moment was nice, I hope that Lucy is my love rival gag ends already. Let NatLu and Gruvia happen and the point is all moot.
Sting and Rogue more of a fight than I thought, I guess they can hold Mage Guille back until help arrives. I figure all of the dragon slayers will cross paths soon.
The Minerva cooking thing that was weird but funny at the same time, seeing that side of Minerva that had me rolling eventhought it was Lily's overactive imagination, I think Happy is rubbing off on him. We actully get some info on Lily and what taste in women he has, does Charles know how to cook? If not, Happy you don't have to worry about Lily taking your woman. I worry this could be forshadowing that he is going to try push Gajeel towards Minerva. My favorite ship is Gajeel x Levy, so I won't be happy if he tries to mess with that.
Now I imagine Edolas, Pantherlily cooking for his comrades, Knighwalker, Sugerboy, Hughes, Coco, etc. complementing him on his cooking. We all agree Erza can be scary but only Pantherlily can truely know which Erza is more scarier, Scarlet or Knightwalker? I seen enough of both of them on bad days that I know it is not plessent when they are in a bad mood.
So two more demons go down, I think this chapter does hint more that Natsu is E.N.D. Can't wait for the next chapter whatever it's called.
