At the start of the game, players take on the role of an unnamed adventurer arriving on a small, unknown island. The island's inhabitants welcome you but warn you of a threat. A dark force is silently eroding the island, and the maple trees are gradually losing their vitality. To save the islanders, players must bravely fight against the dark force's minions and unravel the mysteries and secrets hidden throughout the island. As the game progresses, players will gradually uncover the true purpose of the dark force and, together with other adventurers, protect this beautiful land.
