Twilight is a character from Spy × Family, a Japanese manga series written and illustrated by Tatsuya Endo. The character was voiced by Takuya Eguchi.
Twilight is a spy from Westalis, who has extraordinary combat, memory, and information processing capabilities. 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 a prestigious school that needs "both parents to be present." Hence, he creates a false family by adopting Anya and marrying Yor. He is skilled in cooking and cleaning. As "Loid Forger," he camouflaged himself as a psychiatrist at Berlint General Hospital. Formerly a war orphan, he became a spy to create a "world where children do not cry."
A spy on an undercover mission gets married and adopts a child as part of his cover. His wife and daughter have secrets of their own, and all three must strive to keep together.
