From Animenfo:
Party-girl Ayaka Kisaragi 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 cabalists to solve each case with flair and style. Too bad style doesn`t pay the bills! No matter the terrors the dark can bring, Ayaka will be sure they get a kiss good-night from Phantom Quest, Corp - if she can wake up in time!
