Spy x family (Sxf and OC)

The world balances on the edge of war. Only Operation Strix - a delicate mission of infiltration and deception - stands between peace and destruction. For the master spy Twilight, the plan is simple: create a false family, enroll a child into Eden Academy, and use them to get close to his target.

But fate has a way of complicating even the most precise missions.

At the orphanage, Twilight expected to find one child. Instead, he walked out with two. Anya - cheerful, unpredictable, hiding a secret of her own. And Amy - calm, unreadable, a child who smiles without warmth and stares like she sees straight through him.

To the world, they are the Forger sisters. To Twilight, they are cover. But Amy carries shadows of her own - a past the spy world has long since tried to erase. While Anya dreams of family, Amy plays the perfect daughter... yet beneath her mask lies something even WISE has never accounted for.

Two children. One mission.
And a false family that might just decide the fate of nations.
