No Ivory is considered the final "story" boss of 3U. After, you get 3 extra hunts. 1 is Deviljho if you beat Ivory directly, the second is only obtained after completeing every other quest in village, and that is the Mark of a Hero Arena where you fight Ivory, Brachy and Azure. The last is Alatreon and is only gotten after beating the Mark of a Hero quest.
