@Sky, i was replying to Mega on why i don't think the leaders will be out by the end of the series.


 * 1) The leaders already said it'll take ten thousands of years to beat 666.
 * 2) There will be a war with the other world. And without the leaders it means the war won't end so easily.
 * 3) Unsealing the leaders won't be an option since that would mean they are unsealing 666 too. Do that and they face an additional enemy.
