Plot
Naota's life is confined to going to school and living with his father and grandfather. The usually boring life in Mabase is rudely interrupted by the arrival of Haruko Haruhara, who bursts on the scene by running Naota over with her Vespa scooter and hitting him on the head with a blue vintage Rickenbacker 4001 left-handed electric bass guitar. Later, Naota is shocked to find Haruko working in his house as a live-in maid.

Haruko's search for the alien being, Atomsk, puts her at odds with Medical Meccanica, the monolithic industrial corporation. At the same time, Naota is being watched by Commander Amarao. The Commander believes Haruko is in love with Atomsk and that Medical Meccanica is out to conquer the galaxy. The combination of circumstances get Naota involved in a three-way battle between Haruko, Amarao and Medical Meccanica.
