My old guild told me there is a new island at hawaii that you unlock by doing pre-quests and the quest. They said it wasn't on the net since it's a new quest from new version wlo. They said things like, "you need to do joan in avignon", " you need to kill Dracula, cerberus, medusa, totem and other things", " you need to do the totem quest at inca". One people say, that item sell very quick at the new hawaii island. So I didn't know if that island was really existing, or if it's just a lie.

There's Hawaii in this game , u can find it on world map. It consists of 2 island a small and a big one. The small islan has a shop wher NPC sells rank18 stuffs good for compound ( fine grass , fine golden rose , fine leaf etc.) and some kind of food, coffe and energy drink. There's a big Island where are hyppo monsters. There's a star quest minigame for example, a gold ore collector space and the original space of carnie in a cave. Also there's a blocked part but i don't know which quest unblock it sorry.
In fact you friends didn't lie at all , just was speaking about the 2 different island which is close to each other :)

Only gold ore collection spot is availbile in carnie (aka pleasure island/taiwan) island, not hawaii....

They said there was a 3rd island >.>, not the small or the big one.

If you can find it and upload a screenshots, that'll be helpful.

I'm curious what the third island would do though.....

I don't know if that exist, so that's why im asking XD

ah, hmmm, I guess I can go check it out, but I doubt there is a third island.
