yes i strongly agree with you. because the time when laxus was trying to rule over, natsu and gajeel can pass bcoz 80 above cannot pass freed's rune. maybe their are 400 years of existence. and my theory is natsu and zeref are brothers. bcoz majority of animes made is their are siblings who is in the dark side and the other one is in the good side.
