"Our Family's Special Mission"
The Sato family consists of their only daughter, Minami (Yurika Nakamura), her father, Toshio (Rutaro Koichi), and her mother, Shinobu (Sei Mahi). At first glance, the Sato family seems like a normal family, but they have a big secret that they cannot tell their neighbors. They are a pseudo-family with no blood ties, as Toshio is an intelligence operative, Shinobu is a sniper, and Minami is a skilled fighter who have infiltrated Japan as spies.
