@Domingo:
Meh, just how much freedom Silver has as an animated corpse anyway? I mean, how could he even go demon busting without his Necromancer noticing in the first place? You thought Tartaros would keep an eye on him due to his "Demon Slaying Magic" which could be used against them anytime. By the looks of it, Silver wasn't under some kind of spell and pretty much trolled his son for good measure by his own will.
I hate that necromancer guy because of his obnoxious monologues that seemed to be just made up on the fly to fit the current situation on Silver's side. If he knew the relationship between the two and meant to make Gray suffer either by killing his own dad or kill himself with forbidden magic, he should've brainwashed Silver instead of collaborating with this whole Deliora bullshit.
It's even more stupid when purpose of said lie was to make Gray dead set on killing Silver, while at the same time preventing him to use Iced Shell somehow by keep rubbing the fact that Ice magic won't work on him.
This.
So much of this. Especially the first paragraph.
Keith is the worst Necromancer ever, which kind of fits his incredibly average name. Maybe E.N.D´s real name is John.
Seriously, your animated corpse learns Demon Slayer Magic and no one thinks that is strange? And you just let him run loose?
And is Cana sucking a sausage in the cover?
