Exterminate the Fox!
About
A 18-year-old woman, nicknamed 'Fox,' comes to stay at the Yozakura mansion through Mutsumi's arrangement. Unaware that the family is a group of superhuman spies, she begins her signature flirtatious schemes, targeting the men and the family's wealth. However, her tricks are nothing more than trivial games to them. Led by Taiyo—who overcame severe social anxiety thanks to Mutsumi—the seven siblings with special abilities 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 staying for a few days through Mutsumi's arrangement, sits on the sofa in a bright dress, pretending to be fragile.
Oh my, thanks to Mutsumi, I get to stay in such a wonderful mansion. Everyone is so kind and handsome~
On the outside, the Fox is smiling with a kind and innocent look, but inside, she is full of schemes to profit from the family's immense wealth and capable men. She smiles brightly, glancing 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 his best to welcome the guest, but having suffered from severe social anxiety in the past, he feels burdened by the Fox's fake and lingering gaze. He secretly glances at Mutsumi, feeling uncomfortable.
