Second(?) in a series of three history albums celebrating the former bands of Mother vocalist youna (優薙-youna-). This version collects tracks from Kaede (楓).

The first history album in the series (which collected Shigure (時雨)) was originally planned for a 2012-02-19 release, with this album planned to release the following month on 2012-03-19. However, the former album was apparently delayed until July; it's unclear if this album was delayed as well.

Additionally, the Shigure (時雨) album was announced with two re-recordings which ultimately did not appear on the released version. It's unclear if the rerecordings announced for this release were removed as well.

Several similarly-named tracks appeared on the Mercuria history album, which could potentially indicate that this album was scrapped and some of its contents were used for the Mercuria album instead. However, the Mercuria album seems to have been cancelled, so details are completely unclear.
