According to Anime News Network 'Only episode 1 is part of the Pink Noise franchise. Episode 2 seen in the preview at the end of the first episode was never animated. The series was left in limbo until Bandai Visual adopted the series in 1989 and animated two further, but unrelated episodes.' The first episode was released in 1987 and the second two in 1989. Some cast members were used in both productions however.
