This is a limited production, special specification, high-resolution compatible portable audio player created in collaboration with Astell&Kern and the TV anime “THE IDOLM@STER CINDERELLA GIRLS U149.” The main body design includes various original elements that reflect the worldview of the work, a package with newly drawn illustrations, and a special leather case with an original design made of genuine leather as a bonus. Furthermore, as a premium bonus, the TV anime theme song “Shine In The Sky☆”, which has been mastered exclusively for high-resolution sound sources, is pre-installed as a 96KHz/24-bit high-resolution sound source equivalent to the master sound source.
