In the aftermath of the band's hiatus ("freezing") in 1988, P-Model's members went their own separate ways.

After releasing three solo albums, frontman Susumu Hirasawa rebuilt the band out of several backing members from his concerts.

On this album, P-Model introduced a machine-like, sci-fi sound to its style, heavily influenced by Amiga computers, which Hirasawa and Kotobuki used for production.

This extended to the lyrical themes of the album, being focused on science, technology, and computers.

The total running time of the last track (the last two songs with 3 minutes of silence separating them) is 8:48.
