In autumn 2005, a series of consecutive single releases are announced, leading up to an album release in winter. The singles are announced with tentative titles and release dates at the end of each month only through Visunavi in 100 copies; for example, the first single, "空管、ラッカ音。" is announced for a September 29th release.

However, the release of the latter two singles end up being delayed, as they are eventually released in January and February 2006. It appears the album, originally scheduled for a winter release, is never materialized.
