okay i've done this a hundred times so listen up this crap is easy,okay first of all you need to level up some more then if you dont have their ultimate weapons then get them if you cant then get the weapons you know you can get now then i would recamend using squall,rinoa,and zell.now if you havent got rinoa's dog's moves learned then get that done,the most important moves to learn are invisible moon and wishing star.okay now for the battle itself,first start off by casting meltdown,and refelect on the enemy like fishman said,next cast haste,then protect,and then shell,after that if you did everything above that i told you to do it will be a very VERY easy battle.now all this shouldn't take that long if you dont think about it,oh and believe me after rajin,and fujin things are gonna get thougher,so if you did every thing above then i just prepared you for future battles,you'll thank me for all this if you do it correctly.hope i helped out some.
to protect the people near and dear is what ill do every one i promise i wont let you down
