A boy taking a walk meets a mysterious young girl up a telephone pole. They get to know each other and quickly fall in love… and one thing leads to another. He later wakes up alone in his bed, wondering if the past few days have been all a dream.

The story is mainly centered on Kakeru and his relationship with four girls from his high school. It focuses on one girl per episode - the cute and friendly Urara in the first, the forsaken tennis girl Rie in the second, the dog-owning painter Hikari in the third and the tough-fighting motorcycle girl in the final episode. Which girl will Kakeru choose to be with by the end of the fourth episode?

Nazi Germany - 1944: As American bombers soar towards Berlin, a revolting Satanic rite takes place below - Hitler and his minions are using the monstrous Nazi Death Rape Machine to render the dimensional boundaries separating the Human World from the World of Man-Beasts and the World of Monster Demons. Dr. Munhihausen Sr.’s life work is about to come to fruition - the conjuring of the Overfiend!

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 Juujinkai (a half-man, half-beast race). Once every 3000 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.
