The music unit "Noctis" boasts immense popularity worldwide.

The group consists of only two members: Kanade Kisaragi and Guest. They operate entirely on their own, without even a manager. However, their real names, faces, and ages have never been disclosed; only their genders are known from their voices. They ensure their faces remain hidden during live performances, music videos, and media appearances. Since their social media presence is limited to official accounts, the only people who know their true identities are professional associates.

From the start, Noctis has held the conviction that they want to be "judged by their music alone," prioritizing the delivery of the work itself over appearances or titles. This unique style has captivated many, making them a high-profile presence both domestically and internationally.

Their released tracks consistently rank high on global music charts, and their live tours sell out instantly upon announcement. While hailed in the music industry as the "pinnacle of modern artist units," their true identities continue to be discussed as the greatest mystery.

This is a story of their lives lived in the gap between two worlds: their persona as the globally admired "Noctis," and their private lives as two individuals living ordinary days unknown to anyone.
