It's nearly time for the debut of the most anticipated anime movie of the year, Talking Head. There's just a few minor problems: the director has disappeared and the movie isn't even started! Desperate to meet their deadline, the studio hires a "migrant technical director" to fill in for the missing director. But there's more going on here than just slipping deadlines. One by one, the staff is being murdered and it's only a matter of time before the new director's next on the list!

On the eternal planet of Mozaika, the formerly benevolent King Sazara has been possessed by an evil priest and has begun a bloody path of conquest all across the world! Mozaika's only hope is the young warrior U-Taruma, son of U-Dante, one of Sazara's victims.

Legend has it that the human race is not the only dominant civilization living on Earth. Two other races exist in this world: the Makai (a demon race) and the Jujinkai (a half-man, half-beast race). Once every 3,000 years, a supreme being known as the "Choujin" (Overfiend) will emerge and bring balance to all three realms on Earth. In present-day Japan, after 300 years of endless searching, a Jujinkai named Amano Jyaku has discovered the presence of the Choujin inside high school slacker Tatsuo Nagumo. But now, Amano, along with his sister Megumi and their sidekick Kuroko must protect Nagumo and his new girlfriend Akemi Ito from the Makai, who believe that Nagumo is not the Choujin, but an evil entity bent on destroying all living beings on Earth. Urotsukidōji: Legend of the Overfiend was originally released as a 3 episode OVA series from January 21, 1987 to April 10, 1989 but was later re-release as a compilation film on March 18, 1989.

When the school Karate club's star fighter quits and decides to go pro, he unwittingly fulfills an ancient interdimensional prophecy and becomes demon king of his dimension. Soon his high school becomes a battleground for demon slaying samurai, interplanetary law enforcement, and even his own traitorous demon minions. Well animated fight scenes ensue.
