Nanako is doing her usual chore of cooking, but the fish she cooks burns and, before that, breaks a dozen plates that were handed down through the Ogami family, which later makes Dr. Ogami angry at her. This is typical of Dr. Ogami, as Nanako does get into a lot of trouble. She gets mixed up in a fight between Kuron and Komanechi, two old people who reside in the hospital.

After running out for a few groceries, she returns to meet Dr. Ogami and the Army. They are conducting an experiment, but she is doing her usual exercises that Dr. Ogami has planned for her. After she finishes, she returns to the experiment, just as it goes haywire. The experiment kills a few officers, and Nanako is sucked into the goo-like monster. She has also caught a cold, so the flu virus helps to weaken the monster as she continuously sneezes. Dr. Ogami rescues Nanako and defeats the monster. The monster freezes and falls apart, ending the disaster.

Nanako and Dr. Ogami float to safety, and so begins the operation. They strip Nanako down and tie her up to begin the procedure. Dr. Ogami participates, but is really there to sabotage the entire experiment (not to mention cure Nanako). Before putting her under, Dr. Ogami tells Nanako that he called the Army to rescue them.

After the first step in the experiment is completed, the Army and Air Force arrives to destroy the area, and the experiment is a complete failure. Another monster goes berzerk and starts killing people left and right, including the head of the experiment, Griffin. Saint, however, escapes with the information about the experiment, hoping to sell it to the highest bidder. Dr. Ogami and Nanako escape into a river and wind up near a waterfall. Dr. Ogami dreams of the past Nanako and himself falling in love, and the past Nanako encourages him. Nanako and Dr. Ogami are eventually saved by the rest of the gang.

However, after returning to the base, it is revealed that Dr. Ogami was to be assigned to SkyLab 5, the newest orbital space station. Realizing that the assignment was really a means to hide him, Dr. Ogami refuses, stating that he will not work anywhere that doesn't have fish. After the Army offers to send up as much fish as he wants, Dr. Ogami adds that he prefers grated radish on his fish. After the Army agreed to this request, Dr. Ogami finally stipulated that only one person is allowed to grill the fish and grate the radish... Nanako! When she realized what Dr. Ogami meant, Nanako groaned in discouragement.
