History

Fiona was taught by Twilight to become a spy, but she did not allow her emotions to hinder the task at hand. However, the more she collaborates with Twilight, the more she develops feelings for Twilight. 

When Twilight was assigned to Operation Strix, she wished to be working alongside him as his wife, however at the time, she wasn’t available because she was performing another procedure. She was instead confined at Berlint General Hospital in order to be undercover in the role of an assistant to Twilight to provide him with information regarding the missions. 

The more she sees Twilight, she begins to realize that Twilight is developing genuine feelings towards Twilight and the Forger family; however, she finds this characteristic of his more charming. When the two are given the task of locating the artwork “The Lady in the Sun,” she names them as husband and wife in the tennis match, expressing her affection for him.

Relationships

Loid Forger

Twilight was an advisor during her training as a spy. She taught her to put aside her feelings and not show any weaknesses. Perhaps because of the time she spent with Twilight, Fiona fell in love with Twilight and is now pursuing the desire to become Twilight’s wife, replacing Yor, whom she thought was insufficient for the job.

Yor Forger

Fiona is of the opinion that Yor isn’t as good in her role as Loid’s wife. Fiona is jealous that a woman much lower in ability is capable of playing his wife with such ease, and manages to provoke genuine emotions from Loid whenever she is at his side.
