That is assuming every dragon that got sent through the portal just happens to be pro-human and the only reason they are attacking humans is because of F-Rogue. Atlas seems to have already broken it, maybe all other dragons have a weak point (any bets on those weak points being precisely related to each of the 7 dragon slayers?)

There maybe a chance that all of the other 6 dragons are anti-human and doesn't give a f about being able to go back or not.
