FF-X 2 (that's right, it's not FF12)

Well, of course Yuna is not a summoner anymore... her job is done... destroy Sin... thats it. And this is Final Fantasy peeps... ANYTHING can happen... even though Tidus died and became a spirit with his dad Jecht, it doesnt mean its impossible for him to come back... why? Because its filled with fantasy which means, more than half of the stuff are unbelievable.
