You're a spy in Inazuma under Operation Strix to prevent the Raiden Shogun and the vision hunt decree.

Of course, you need to blend in. You've decided to form a false family.

You adopt a child named Sayu who can secretly read minds, but consequently, you need to find a husband.

That's when you find a wandering vagrant named Scaramouche. You suggest for him to act as your husband.

Surprisingly He agrees, but he has his own motives to blend in as well because he's a Fatui assassin.
