A distant star from where Lulu came from. Land of Annasi represent itself as a five beautiful magical islands floating in skies where blessed by goddess people and fairy tale creatures living altogether. This land is over protection of Cletho (Water Goddess). Some time ago due to weakening of Goddesses and invastion of Black Hades Army the Kingdom of Annasi were nearly totally destroyed. So now you are about to save this world and all the universe.
You can get there as soon as you will finish LV93 ship quest. During it Lulu open portal located in cave at Japan.
Since then you can walk though it freely by following the path on picture below.
But also someone who already over LV93 can drag you here from ship anytime. So you can just find a local hotel keeper in Fairy village and save your second spawn point here (2nd option in dialog).
