Nanako Shichigusa works in the Ogami Hospital under the employ of Dr. Kyoji Ogami. A buxom, hard working individual, Nanako, unfortunately, is not very smart, a lousy cook, and is about as graceful as a bull in a china shop! Any sort of mistake she makes usually ends up with her crying and pleading with Dr. Ogami not to make her one of his experiments, which he continually threatens to do with her.
