Former Air Force Master Sergeant Kamoi Tsubame tries changing careers to finally get cute girls to wear her cute self-designed clothes. To that end she tries to get a job in the Takanashi household as a maid and babysitter to Yasuhiro Takanashi's spoiled daughter Misha Takanashi, as it seems that her mother is no longer present. Misha has successfully gotten rid of previous maids through playing devastating pranks like throwing mud, laying out banana peels to slip on and lighting the washed clothes on fire. In face of the newest applicant boasting that she has military experience, Misha even thinks about researching bomb making.
