Requiem From The Darkness is a recent anime release, that I just caught the second volume of, episodes 5-7.
This is definitely a darker anime than most. Washed in color and sound, with distinctive character desingns, RFTD has plenty of mood, style, and twisted supernatural stories to draw you in. Each episode's formula pits the protaganist against a changing backdrop of supernatural evils to be thwarted by a mysterious trio he follows.
