"A Mighty Stardust" is an original song featuring Stardust. According to the producer, Stardust was born in the darkness of high dimensional cosmic and lived in the vast space-time, where she felt lonely and helpless. As time passed, she overheard a signal emitted from a spacecraft of earth; a wavelength filled with love that impresses a heart: a song. Stardust musters up her bravery and flew toward the spacecraft and for the first time, she sings "The Mighty Stardust". The people from within the spacecraft finds her and takes her back to earth. The entire earth sang her brilliant song to her and from then on, she would bring the world more beautiful songs.
