Arale and her friends learn of a World Grand Prix being organised by the Radial Kingdom. The prize is marrying Princess Front (a dead ringer to Ms. Yamabuki) or 1 million dollars. Of course they decide to enter for the money. Not so for Dr. Mashirito; he is going for the princess and will stop at nothing to win! The princess though has her own plan, which involves Ms. Yamabuki, and that of course means even Dr. Slump decides to enter with his trusty Borobo. Let the race begin...

Boston, United States. Dracula, the immortal vampire, interrupts a satanic ritual and flees with Dolores, the woman whom the members of the evil cult are about to murder. Overwhelmed by his love for her, and unable to drink her blood, they have a son together, whom they name Janus. (Loosely based on Marvel's The Tomb of Dracula comic book series.)
