Warmongering forces constantly jeopardize the thin veneer of peace between neighboring countries Ostania and Westalis. In the bustling Ostanian city of Berlint, secret agent “Twilight” dons the alias of “Loid Forger,” an esteemed psychiatrist. His intention is to gather intelligence on prominent politician Donovan Desmond, who only appears rarely in public at his sons’ prestigious school. With the help of unmarried clerk Yor Briar to act as his wife and six-year-old orphan Anya as his daughter, Loid enacts his master plan. He will enroll Anya in Eden Academy, where Loid hopes she will excel and give him the opportunity to meet Donovan without arousing suspicion. What Twilight doesn’t know is that Yor is actually an assassin, and Anya is an ESPer.
