Let's continue with an old favorite for manga-boom-era fujoshi. But does this one still hold up?
DESCENDANTS OF DARKNESS (Yami no Matsuei), by Yoko Matsushita. First published in 1996 and first published in North America in 2004.
PLOT:
Between heaven and hell, there is the Ministry of Hades. Here lost souls are gathered and judgement is rendered upon them by shinigami such as Asato Tsuzuki. He and his partner, Hisato Kurosaki, are called upon to solve cases such as a suicide victim whose spirit is stuck in the mortal world or an idol singer under the spell of a vicious vampire.
