Yoshiaki Kawajiri (Ninja Scroll, Vampire Hunter D: Bloodlust) directs this lush animated feature based on the first book in the Wicked City series. The story involves a treaty to be negotiated between the human and demon worlds. Two secret agents, one from each side must join forces to keep inter-dimensional peace till a settlement is reached. Everything from the beautiful old school animation style to the frightening monster designs to the excessive violence is a real treat for the adult anime fan. It should be stressed that the eroticism present in the film is extremely adult, bordering on pornographic. Though decent action is present, the plot is weak in the third act, leaving one indifferent to the conclusion.
