An unnamed spy from Westalis with extraordinary combat, memory, and information processing capabilities. As a master of disguise, he uses various faces and names for each mission, though he is generally known by his code name "Twilight." His most recent mission, Operation Strix, requires him to enroll a child in the prestigious Eden Academy to approach a prominent figure in Ostania's warmonger political party. And so he camouflages himself as "Loid Forger," a psychiatrist at Berlint General Hospital, to create a false family by adopting Anya and marrying Yor, although he is ignorant of their hidden talents. Loid possesses a vast amount of talents and skills in espionage and in real life. Although he appears to be manipulative and pragmatic when accomplishing his missions, he reveals his soft side and shows himself to be a good person to his fake family. Formerly a war orphan, he became a spy to create a "world where children don't need to cry."
