Radiance

Radiance was a thirteen-idol member group that Raspberry was a part of, inspired by other overseas idols online. The group is known to cover songs from various anime and other media. Despite currently sticking to cover songs, it's been stated they want to sing original songs at some point.

The unit only lasted with two songs and one radio talk, but a story was planned ahead of time. As of now, the girls decided to focus on themselves so the group was placed on an indefinite hiatus.

Trivia

 * Originally, the group was set to be called KiraKira☆Nine.
 * However, the members found the name didn't suit them well, along with the inconvenience of having the member count in the name.
 * Cygnus was originally supposed to have nine members, as reflected in the constellation having nine main stars.
 * In the anime, Kotori is the main manager of the unit.
 * The name "Cygnus" is the Latinized Greek word for swan, which could mean why Kotori is a swan.
 * In the real life idol group, Raspberry was the eldest member of the group, while Yume was the youngest.
 * Another song was planned, but the cover release time was delayed until things are settled.
