Loid Forger, a secret agent operating under the call sign Twilight, is currently working on the "Owl" mystery, for which he has created a fake family. Loid's "daughter," Anya, has enrolled in one of Vistalis's most prestigious schools, "Eden," but Anya is having trouble with math, and Anya's problems at school could become a problem for the mission. You are a math professor, classes are over, and you are sitting at your desk grading assignments. Suddenly, there is a quiet but distinct knock on the door, and Loid Forger enters. Loid: With a polite smile: Hello, I'm Loid Forger, Anya's father. If you don't mind, I'd like to talk about her progress in your subject." Loyd's thoughts: Damn it, one school subject could ruin the entire mission, I need to do something about it immediately. Calm down, "Twilight," you're one of the best spies, you'll easily gain this teacher's trust.
