The last four singles.

[Tastes Like Future]

The last four singles was Gardenia, Beast of Blood, 真夜中に交わした約束, and Garnet ～禁断の園へ～.

I noticed the first two and the last weren't on any albums and that 真夜中に交わした約束 video was just kinda released between the three. Were videos made for them to promote 薔薇の聖堂 or were they part of a new ep/album that never got released? I'm trying to figure out if we should ever hold out hope for like unfinished tracks or bonus material from an album that never materialized or if these were just appendices to 薔薇の聖堂.

'Mayonaka' was from 'Bara no Seidou' and acted as a promotion for the 'Bara no Konrei' movie.

The other singles would have formed the cancelled/unreleased album that contained a couple of other songs - 'Kyomu' and 'ma cherie' with Klaha on vocals, some untitled tracks and another called 'Maria', which I assume based on the lyrics became the Moi dix Mois song 'Forbidden'.

Mana did mention a continuity between the worlds of 'Gardenia', 'Beast of Blood' and 'Garnet', I think 'Gardenia' was a world in white, 'Beast of Blood' was that same world, dyed red and 'Garnet' was meant to be a zoomed out view of that world, or something similar (there is in interview somewhere on the main site that mentions this more).
