Crunchyroll is the manga. Crunchyroll is the official kodansha translations. Okay, technically the raws are the most reliable sources of information. However unless someone here can read the raws (I can only recognize certain kanji), the most reliable way of interpreting the raws is to ask a translator. TheFairyTales on tumblr is so far the most prominent translator, and she supports crunchyroll's translations over mangapanda and mangasteam's because they tend to have less translation errors.
We don't know what Mashima hides ofc, but theory about 7 DS has got a lot of weak point.
Sadly, ppl here keep just ignoring it w.o. try even logically explain their points of view.
Well, for example. Weak point # 1.
- There's future Rogue timeline - GMG + 7 years (current manga + 6 years).
FT Rogue said Acno rules over world. Ok. But F.Rogue is two elements DS himself (white-shadow) + he's able to use dragon manipulating magic.
So, I've two remarks:
1. Where he got dragon manipulation magic ? By another dragon /dragon slayer ?
2. How he knew principles of usage this magic ? (he said how m, dragons he is able to control at same time and about that magic doesn't work on Acno). Where he got that experience ?
3rd but main - Why Acno didn't kill FT ? It was so impossible for Acno ? xD
Acnologia said that there are only 7 left until he wipes all traces of the dragons from this world. He says this immediately after he kills off God Serena after saying that he smelled a dragon. It's pretty strong evidence that he's gunning for the Dragon Slayers because they're the last traces of the dragons. It's
possible that some other dragon exists, though they would most certainly be hiding and unlikely to be relevant to Acnologia. The movie seems to imply that there are some unknown dragons might show up. Not enough information is known about those, and they could be artificially created ones or something. As far as the manga goes I really don't think we're going to be seeing any new dragons or dragon slayers pop up. One thing is clear: Regardless of whether or not there are more dragons/dragon slayers other than the 7DS,
Acnologia believes that the 7 dragon slayers are all that's left and he's hunting them.
Rogue said he invented Dragon Supremacy magic himself, and I don't see why we should doubt him. Being the creator, he probably has some confidence in it. He believed it would work against dragons, but it failed to work against Acnologia so he went back in time to find some. If there were dragons in Rogue's future, then there is no reason to go back in time in the first place.
What do you mean Acnologia didn't kill FT? In Rogue's future? He did. Or at least, he stomped all his opposition. Rogue mentioned that he comes from a future in which 90% of the human population was gone. Now it's conceivable that some people survived, but it's likely that they survived because Acnologia didn't care enough to personally hunt them down. That probably explains why Rogue survived.
One more note. FT Rogue called alltime Acno as Acno, but when he said "Natsu was killed by dragon", he used word "dragon". It's pretty clear with phraseology that "dragon" wasn't Acno.
But that was before Rogue admitted that he was lying about the dragons coming, and then specifically said that Acnologia was the lone ruler of the world. As far as Rogue knows, Acnologia is a dragon so when he says that Natsu is killed by a dragon that isn't entirely inaccurate either.
