This is the next installment in the praised Atelier Iris series. The game starts out in the setting of Eden, a magical land of mana and alchemy. You start the game by playing as Felt, the series' first chacracter to use a sword, and Viese, a new, but very talented alchemist. Parts of Eden are disappearing and Felt must wield the Azure Azoth and go through the Belkyhde gate to reach Belkhyde to help resove the problem.
The game's key feature will be the so-called dual scenario system, under which each protagonist will play a particular role. The system will allow players to switch between the two protagonists at will.
