While on vacation with your friends, you are suddenly washed away to a mysterious island in another world. Now you must befriend the locals, gather resources, and build Paradisiem Island into a bustling tourist destination so that you may go home!

It's summer. You and your friends are on vacation, when suddenly the sea carries your boat away to an unknown island in another world. This island—Paradisiem Island—is small, with one village. According to the village chief, the island's Guardian Deity foresaw the arrival of you and your friends, and they want you to help the island return to its former glory. Without more tourists, there aren't enough people to worship the Guardian Deity, whose powers you need to return to your home world. Work together with your friends, Sahoto, Mei, and Chiyo, as well as some new friends you make on the island, to help it grow and prosper into a popular tourist destination!
