"Thousands of years ago, a prophecy left in <Siju History> said that human and nature need to reach a balance, or else a world devastating disaster would occur. But as history has shown, this balance is never easy to achieve. Though Human doesn't always mean it, they tend to over-exploit and disrupt the delicate ecological balance thus sending the world down the path of destruction. Fortunately, the proud and brave Water Sprite leads their partners to form a powerful environmental task force. They will bravely face this crisis and do whatever it takes to save the wetland world and preserve it for future generations."
