Summary
After the death of one of their diplomats in a car accident in Ostania, the heads of Westalis meet to discuss the situation. They believe it was not an accident but an assassination by the East's far-right political party. Suspecting that they are planning a war against Westalis and needing to learn of their plan, one of them suggests they send their best agent, "Twilight." He is an agent that works for WISE, Westalis's intelligence agency, and is tasked with investigating Donovan Desmond, the leader of the political party secluding in Ostania. To do this, Twilight must get married and have a kid, who he must enroll into Eden Academy, a prestigious private school that Donovan's son attends. Twilight disguises himself as a psychiatrist Loid Forger and adopts a girl named Anya so that he can enroll her in the school. Unbeknownst to him, Anya is actually a telepath who can read minds.

Heading home, Loid instructs Anya to say she was always his daughter and to call him father. After settling in their apartment, Loid begins heading out to get some stuff and forge an ID for Anya, but Anya insists on going with him. The next day, Loid goes out alone to meet with his informant, Franky Franklin, leaving Anya at home with a barricade to prevent her from following him. Bored, Anya plays with Loid's spy equipment and accidentally reveals their location to Edgar, one of Twilight's enemies. Upon returning home, Loid notices the front door barricade tempered with. Entering inside, he gets ambushed but manages to beat all the men. Unable to find Anya, he concludes she is kidnapped and that he is now compromised. While thinking of running away and restarting the mission, a man attacks Loid from behind.

Loid disguises himself as Nguyen and rescues Anya at Edgar's hideout. Outside, Loid gives Anya a note and directs her to the police, hoping to give her a better home. Loid chastises himself for putting a little girl in danger and regrets forgetting that he became a spy in order to create a world where children won't have to cry. Anya, who read his mind, decides to stay and wait for him. Loid returns to the hideout and defeats all of Edgar's goons, then forces him to withdraw by threatening the man's daughter. Walking out of the building, Loid is surprised to see Anya waiting for him so they can go home together. Recalling she was returned each time after adoption, Loid takes her in.

On the day of the exam, Anya tries to read the mind of the other kids, but they all are panicking as neither of them knows the answers. However, she then remembers what she studied with Loid and writes it down. After the exam, Loid and Anya look at the board with the passed students. Loid is elated to see that Anya is there, and all his exhaustion hits him, making him fall to the ground. Later at home, Loid and Anya learn that the second phase of the admission process is a family interview, and both parents must be present, meaning that Loid must find a wife.

At Berlint City Hall, a 27-year-old clerk Yor is ostracized by her coworkers for her aloof nature and being single at her age. With the increase in spies, people have started reporting anyone they believe is suspicious, worrying Yor. Camilla states she is having a party this weekend and invites Yor to come with a partner. That night Yor receives a call from her brother Yuri and tells him she has a boyfriend, but he decides to have his friend confirm at the party. Shortly after, the Shopkeeper calls, stating he has a client for Yor, the "Thorn Princess," a deadly assassin.

The next day, Loid goes to a tailor to get Anya measured and encounters Yor, and the two agree to help each other to fulfill their respective goals. However, on the day of the party, Loid gets caught up with an extra mission which causes him to arrive late and accidentally introduce himself as Yor's husband. After they leave the party, the pair are pursued by some of the remaining enemies from Loid's earlier mission. They stop at an abandoned factory, where Loid and Yor fend off the men together. Yor realizes she and her cover can benefit from their partnership and suggests to Loid that they should get married. Loid agrees and uses a grenade ring as a ring while he pledges his vows to Yor.
