This is the 12th album by ironomi, whose concept is to "sound the various colored fruits of the seasons". In its 16th year of activity, this is the first album to focus on the theme of the four seasons. The scenery changing from winter to spring, the freshness of early summer, the joy of autumn harvests, and the dyed mountains. The colors of the four seasons are turning and twinkling to the stars in this story. The colors of the four seasons, mixing and melting, meeting each other, rising into the air, the sound of the stars. The light leads us to the sound of the stars.
