This game is part of a larger project that brings to life the world of Yana-gi’s upcoming album “Green Light,” set for release on February 28, 2026. It includes an original album, this game, and a solo live tour.

The story unfolds in an ordinary rural town where people quietly go about their lives. Once known for its mining industry, the town has long since exhausted its stone resources. Recently, strange rumors have begun spreading: everyone who sleeps in this town dreams of the same thing—a bizarre yet delightful dream…
The local hotel is now unusually bustling with visitors drawn by these mysterious dreams. Midori, a part-time worker at the hotel, becomes deeply intrigued by stories from outsiders arriving in town. Her curiosity will eventually lead her to uncover the town’s hidden secrets.

The game unfolds in two distinct parts: the “day world” and the “night world.”
In the day world, Midori interacts with various people around the hotel where she works. Through conversations, helping others, and building connections, players may uncover vital clues.
Meanwhile, in the night world, players explore a surreal and mysterious realm—venturing through fantasy dreams, sci-fi-inspired dreamscapes, love story-driven dream narratives, and more. Using information gathered from reality, players will unravel hidden secrets buried within these dream worlds.

Additionally, Hako Seikatsu—the developer behind the adventure game “Unreal Life”—is involved in development as well.
