what if natsu saw igneel die in front of him, then went to train to become stronger. he just left a note said: "I'll be back someday". natsu and erza and mybe i'll put gray and juvia, and some others. this is my first fanfic. kind of dark natsu but will not be at the end, and not to erza. wendy, and gajeel are in it they are like brothers, and sister to natsu.
