The game follows the story of Setsuna, a young woman who lives on a remote island. She possesses a special ability known as the "Deep Sea of Dreams," which allows her to sense the emotions and memories of those around her. One day, Setsuna's village is threatened by a group of monsters, and she sets out on a journey to save her home.
The gameplay involves exploring the world, battling monsters, and interacting with non-playable characters (NPCs). The combat system is turn-based, and Setsuna can use her abilities to attack enemies or support her allies. The game also features a "mood" system, which affects Setsuna's abilities and interactions based on her emotions. I Am Setsuna Switch NSP Free Download
