For the agent known as "Twilight," no order is too tall if it is for the sake of peace. Operating as Westalis' master spy, Twilight works tirelessly to prevent extremists from sparking a war with neighboring country Ostania. For his latest mission, he must investigate Ostanian politician Donovan Desmond by infiltrating his son's school: the prestigious Eden Academy. Thus, the agent faces the most difficult task of his career: get married, have a child, and play family.
Twilight, or "Loid Forger," quickly adopts the unassuming orphan Anya to play the role of a six-year-old daughter and prospective Eden Academy student. For a wife, he comes across Yor Briar, an absent-minded office worker who needs a pretend partner of her own to impress her friends. However, Loid is not the only one with a hidden nature. Yor moonlights as the lethal assassin "Thorn Princess." For her, marrying Loid creates the perfect cover. Meanwhile, Anya is not the ordinary girl she appears to be; she is an esper, the product of secret experiments that allow her to read minds. Although she uncovers their true identities, Anya is thrilled that her new parents are cool secret agents! She would never tell them, of course. That would ruin the fun.
Under the guise of "The Forgers," the spy, the assassin, and the esper must act as a family while carrying out their own agendas. Although these liars and misfits are only playing parts, they soon find that family is about far more than blood relations.
After his parents died, Shinpei Ajiro lived with the Kofune sisters, Mio and Ushio, but he has since moved to live on his own in Tokyo.

Taking a step back, Shinpei becomes convinced there must be another explanation. Dangerous entities roam among the islanders, and a vision of deceased Ushio asks him to "save Mio" as her final request. He is certain that something is afoot—and Ushio's death is only a piece of the puzzle.
With the help of Mio and various others, Shinpei struggles to forge a future in which he, his friends, and family can stay alive. But the more he investigates, the more impossible such a future seems. This darkness infiltrates his home island. Just how much more suffering will he go through before finding the right path to save it all?
Yuuichi Katagiri has battled financial hardships his whole life but has learned to stay content and positive thanks to his close circle of friends.

But when the gathered money mysteriously goes missing, suspicion falls on two of Yuuichi's friends: Shiho Sawaragi and Makoto Shibe, who were in charge of collecting the payments. Although innocent, Shiho and Makoto take responsibility for the failure to protect the money when no one else comes forward.
A few days later, Yuuichi and his friends receive mysterious letters which trick each of them into meeting up. Upon arrival, they are ambushed and knocked unconscious. They wake up in a mysterious room in the presence of "Manabu-kun," a character from a controversial children's show that stopped airing due to its malicious content. He informs the group that one of them indirectly gathered them together in order to settle a large debt. They are to play a "friendship game": a series of games that will test the strength of their bond and trust in each other. As the group's faith wavers due to the growing number of secrets and betrayals, Yuuichi must figure out who of his "friends" he can actually trust and ultimately discover the identity of the traitor.
