A TV special, known as episode 2.5, that takes place between episodes 2 and 3.

Ungrar, the King of Viruses, has escaped from his prison cell in Vaccine World. Maya, the Goddess of Vaccine World sends Mugimaru down to Earth to find a human to accept the powers of Vaccine World and become the Magical Nurse. He finds the best (and the only willing) person for the job when he meets Komugi Nakahara. Komugi is a playful, lazy, and easily distracted (typical) teenager whose dream is to become a cosplay idol. Balancing her career with the Kiri-Pro Promotion Company and her new job battling Ungrar's loyal henchman, the Magical Maid Koyori, Komugi delights audiences in this parody anime series.

Prior to the events of the anime, three factions—the Garan Army, the Kiba Army, and the Aira Army, battle for total dominance of Machine Island. The island is basically a prison, isolated from the rest of the world. The island contains a vast amount of resources, allowing the three factions to create an infinite supply of giant robots for their respective armies. The world government learns that the island's power reactor has become unstable and will explode within 66 hours, destroying all of life and Earth itself. The government sends the Death Caprice squad, composed of mercenaries Ken Kaido and Ryo Magami to solve the issue, along with their giant robot Mazinkaiser, but was that a good idea?
