Party-girl Kisaragi Ayaka turned her late-night lifestyle into a business that gives new meaning to the term "graveyard shift"! While it may seem easier for Ayaka to round up troublesome spirits than to put a corporate spin on her own free-wheeling habits, she calls upon a powerful but quirky cadre of helpers to solve each case with flair and style. Too bad style does not pay the bills. No matter what terrors the dark holds, Ayaka will be sure they get a good-night kiss from Phantom Quest, Corp — that is if she actually manages to wake up in time.
