Nanako Shichigusa an ordinary high-school student... until her parents run into financial problems. So, the well-endowed young girl must take a job to help out with her parent\'s mounting debt. This reluctant job is a nurse\'s position at a \'highly suspicious hospital\' that is run by the mad scientist, Kyoji Ogami, who also has a policy of hiring some other very odd doctors and experimenting with mecha. Nanako seems to be up against the wall with no other choice but to do her job. But will she be able to see the end of this mess?
