A cool spy and a loving mother!!

Erika is a normal housewife, the kind you can find on any street in Japan. But she has a secret she can’t tell anyone. She is a former spy, who quit her job to live with her salaryman husband and young son. Nobody knows she used to be a spy, not her parents, or her siblings, or even her husband and child.

But one day, her former boss, Tozuka, comes to her and asks her to help him solve some difficult private cases. She refuses for her family’s sake, but he threatens to reveal her secret, and she is forced into helping him anyway...

A cool spy and a loving mother. Erika must shift between these two personas while using her spy skills in infiltration, disguise, eavesdropping, decoding, and combat to defeat a greedy and sly evil!
