Norn9: Norn Nonette is an adventure game developed by Regista and available on Nintendo Switch. The game takes place in an old-fashioned town, reminiscent of the Meiji and Taisho Era, where a giant globe called 'Norn' floats in midair. The globe is set up like a small town, complete with parks and other amenities.

The story follows the journey of elementary school student, Suzuhara Sorata, who is transported to a different time and place after hearing a particular song. In this new world, Sorata meets three young ladies and nine young men, and together they embark on a journey aboard the mysterious 'Norn' ship in the sky.

Norn9: Norn Nonette features three protagonists, each with three love interests, and all characters are voiced. The game provides an immersive experience, allowing players to explore the world and interact with the characters while making decisions that shape the story's outcome.
