Following the closure of Geneon USA, Media Blasters acquired the license and will release the series on Blu-ray in 2025.

[3] The series details the life and history of Nanako Shichigusa, a 16-year-old who works as a maid (not nurse as the title might imply) in the hospital of Dr. Kyogi Ogami, the male lead.

Nanako is a classic ditzy slapstick protagonist who tends to accidentally break things and do everything wrong.

Ogami treats her frequently in a cruel or heartless manner—threatening her, yelling at her and even subjecting her to physical abuse—yet at the climax of every episode he comes through to rescue her from whatever predicament she got herself into.

In the beginning, Nanako was the subject of a cyborg experiment conducted by Dr. Ogami for one of his most powerful robots.

It has been Dr. Ogami's quest to cure the "Nanako illness" ever since he promised the second clone that he would heal her before she died when he was young.

Nanako runs through tough training exercises, such as standing under a cold waterfall with nothing but a bikini on, with the help of Genki.

However, when she gives Dr. Ogami one, he gets angry because she forgot to buy daikon radish, which helps the protein in fish digest properly.

While in the woods, she encounters a giant bear after trying to light a fire, and Dr. Ogami reminisces about past Nanakos in the trailer.

However, Nanako catches a cold and relaxes naked in a hot tub above a fire Kuron built.

Dr. Ogami appears with the stuffed animal that had thought by Nanako to have been dropped off the cliff when she was rescued, but, not only is it a tracking device, it is also a recorder.

Dr. Ogami gets angry and Nanako freaks, jumping out of the tub naked and running for her life.

They attempt to shoot tranquilizers into the monster to stop it, but all fail, and, in turn, make everyone else except Dr. Ogami go to sleep.

While cornered outside in the rain by the monster, Nanako is saved by Dr. Ogami, who manages to put it to sleep.

During her display, in which only Satsuki can control, she is stopped by a robot named Griffith, which also destroys tanks and people in the process.

Outside, in plain view of the wreckage, Nanako soon realizes her suit is running low on battery power.

In the process, an engine aboard the plane explodes after being hit from one of the jets, making flight almost impossible.

Another monster goes berserk and starts killing people left and right, including the head of the experiment, Griffin.

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 agreed to this request, Dr. Ogami finally stipulated that only one person is allowed to grill the fish and grate the radish... Nanako!
