Nurse Witch Komugi(2002)

Nurse Witch Komugi-chan Magikarte

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.
