Former Air Force Master Seargeant 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 babysiter to Yasuhiro Takanashi's spoilt daughter Misha, as it seems that her mother is no longer present. Misha has successfully gotten rid of previous maids through playing "delightful" pranks. In the face of the newest applicant boasting that she has military experience, Misha even thinks about researching bomb making. Fun times ahead!
