Oh, it's only been what? three years of griping on my part before TOKYOPOP at last evinces interest in licensing one-shot, single volume titles.
These are all shoujo, not so incidentally:
-Die Todliche Dolis by Kusumoto Maki - Think Beardsley on crack. -Glass Wings by Asaoka Misuzu -Gorgeous Carat by Higuri You - Suddenly everyone wants her. Kinda like Matoh Sanami. -Sequence by Mizuki Ken - An early work by a very popular illustrator. (Love her Gundam Wing and Battle Royale doujinshi.)
Anyway, I don't know anything about the second, but the rest of the titles are solid ones--and a damn sight better than what TOKYOPOP has been gracing the bookshelves with lately!
