Fake family from "summary" of Spy x Family, Vol. 1 by Tatsuya Endo
In the world of espionage, appearances can be deceiving. Master spy Twilight has been tasked with infiltrating an elite private school, Eden Academy, in order to gather crucial intelligence. To maintain his cover, he needs to create a believable facade - a family. But Twilight is a solitary man, with no wife or children to speak of. So, he hatches a plan to adopt a daughter and enlist the help of a skilled assassin to pose as his wife.
Enter Anya Forger, a young orphan with psychic abilities. Twilight adopts her, not out of paternal instinct, but out of necessity. Anya is blissfully unaware of the true nature of her adoption, believing that Twilight is her loving father. She brings a sense of chaos and unpredictability into Twilight's carefully constructed world, with her psychic abilities causing all sorts of trouble. Yet, despite the challenges she presents, Anya also brings a semblance of warmth and humanity into Twilight's otherwise cold and calculated existence.
To complete his fake family, Twilight recruits Yor Forger, a talented assassin who is looking for a way to escape her violent past. Yor agrees to pose as Twilight's wife, not realizing the true extent of the mission she is embarking on. As the three come together under one roof, they must navigate the challenges of living together as a family, all while maintaining their respective secrets and hidden agendas.
In the midst of their deception, a genuine bond begins to form between Twilight, Anya, and Yor. Despite the artificiality of their relationship, they find themselves growing closer and learning to trust one another. As they face various obstacles and enemies, they must rely on each other in ways they never imagined. Together, they must navigate the dangerous world of espionage, all while trying to keep up the facade of a normal, happy family.
