Misha Takanashi is a second grader with a Japanese father and a Russian mother, who died when Misha was small. Since then she has lived with just her dad. That changes when Tsubame Kamoi arrives to work as their maid. Tsubame once served as a master sergeant in the Japan Air Self-Defense Force, and she is also a devoted lolicon who is deeply drawn to Misha. The result is a home comedy with a slice-of-life feel: Tsubame keeps trying to get close to the girl, and Misha fights back against her every step of the way. The story is adapted from a comedy manga by Nakamura Kanko.
