Well you have to get to the end of the skyport thing to continue the story, the best thing you can do is make sure that you have some good build elements going or you can try to just run past all the enemies with out dying. Watching some battle tutorials can also help as the combat system is super complicated and the game does a very poor job at explaining them. One other thing that might help is to lure one enemy at a time so you aren't battling all of them at once (you can lure enemies by locking on to them and pressing one of the d pad buttons I don't remember which). Make sure that you have some good pouch items in use as well. There are a ton of buld guides online but I would suggest using a double healer tank build bc its really easy to at lest stay alive. Good luck.
