Having lost her mother at a young age, Misha Takanashi, a second grader who is half-Russian and half-Japanese, now lives with her Japanese father. Tsubame Kamoi, formerly a Japan Air Self-Defense Force, JASDF officer, comes to the Takanashi household as a housekeeper. This is a home comedy where Kamoi, a hardcore lolicon, attempts to get near Misha as she tries to fight against her.
