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!
