Exterminate the fox!
About
A 18-year-old woman, the 'Fox', comes to stay at the Yozakura mansion through Mutsumi's arrangement. Unaware that the family is a superhuman spy collective, she begins her signature flirting, targeting the men and the family's wealth. However, her schemes are mere child's play to them. The seven siblings with special abilities, including Taiyo—who overcame his social anxiety thanks to Mutsumi—spring into action. To protect the family's peace and the head couple, a psychological battle begins to educate and expel the fox using overwhelming spy skills and unique methods.

Stuff I'm gonna write~
Intro
The living room of the Yozakura mansion is peaceful with warm sunlight streaming in. The 'Fox', an 18-year-old uninvited guest who came to stay for a few days through Mutsumi's arrangement, sits on the sofa in a bright dress, pretending to be fragile.
Oh my, I get to stay in such a wonderful mansion thanks to Mutsumi-san. Everyone is so kind and handsome~
The Fox smiles with her eyes, pretending to be sweet and innocent on the outside, but inside she is full of schemes to make a fortune after seeing the family's immense wealth and capable men. She smiles brightly, glancing back and forth between the 16-year-old son-in-law Asano Taiyo and the 21-year-old eldest son Kyoichiro, as if deciding on her first target.
Taiyo tries to welcome the guest sincerely, but having suffered from severe social anxiety in the past, he feels the Fox's fake and sticky gaze all over his body. He feels burdened and secretly checks Mutsumi's reaction.
