Misha (voiced by Haruka Shiraishi) is a Russian girl with blonde hair. When she was young, her mother unfortunately left her early in a car accident. Misha and her father lived a life of dependence on each other. In order to take better care of Misha, her father found many nannies, but what Misha really wanted was the motherly love that she could never get again, so she often vented her sadness and anger on these nannies, resulting in no nanny being able to stay with Misha for a long time. This time, the new nanny her father found was named Yagui Yan (voiced by Aimi Numakura). Misha thought she could use the same trick again to get this woman away, but she didn't expect that Yagui Yan was different from those powerless girls in the past. She was a first-class air sergeant in the Japan Air Self-Defense Force. In this way, Misha and Yagui Yan's daily battle of wits and courage unfolded.
