You're a missing person investigator. Your niece, along with her expedition members, has disappeared in the mountains in Greenland.
While looking for them, you open a portal to another world. But soon it turns out that there's not only one world, but three: Arcalium, Atlantis, which is also known as the Underwater World, and the Parallel World!
The balance between them depends on the magic flower called Anima that grows in Arcalium — its pollen produces the oxygen that is vital for Atlantis.
But a stranger from the outer world stole it... You are to find the intruder and return Anima!

* Find all the flowers growing in Arcalium to learn more about its flora!
* Collect the pearls to decorate the house in Atlantis!
* Learn what’s behind the theft of the Anima flower!
* Restore peace between two parallel worlds in the Bonus Chapter!
