Synopsis
The time: the present... perhaps.
The place is an outlying city called Mabase, from which grows the gigantic Medical Mechanica plant.
Nandaba Naota, a smart-aleck schoolkid, gets sideswiped by a Vespa on his way home with his brother's girlfriend, Samejima Mamimi.
When he gets home from school the next day, he finds the woman on the Vespa from the day before in his living room. Naota is stunned as he listens to his father explain that he has just hired her as their new housekeeper. She tells him her name is Haruko.
Naota doesn't know how to react to the fact that he and Haruko are suddenly living under the same roof.
And then there's the mysterious robot that suddenly appears before Naota when he goes out into the night for Mamimi.
Things get strange very quickly...
