The daughter of the Forger family and a first-year student at the prestigious Eden Academy. In reality, she is a telepath who can read minds, created accidentally through experiments by a certain organization. Loid adopted her from an orphanage. While she keeps her powers a secret, she is aware that Loid is a spy, Yor is an assassin, and Bond can see the future. She tries to befriend her classmate Damian, the target's second son, to help Loid's mission succeed, though her efforts often backfire. She struggles daily to become an Imperial Scholar, but with only one Stella Star and one Tonitrus Bolt so far, she has a long way to go.

The father of the Forger family and a skilled psychiatrist at Berlint General Hospital. His true identity is a top-class agent of WISE, the Westalian Intelligence Services' Eastern-Focused Division. His codename is "Twilight." He possesses extraordinary observation skills and memory, and is a specialist in disguise who can use a hundred faces. To prevent war between East and West, he takes on Operation Strix, a mission requiring him to create a fake family and enroll a child in a prestigious school. He leads a busy life balancing hospital work and missions alongside daily housework and childcare.

The mother of the Forger family and a clerk at Berlint City Hall. Her true identity is a highly skilled assassin belonging to the organization "Garden." Her codename is "Thorn Princess." Having lost her parents early, she became an assassin to support her younger brother, Yuri, all by herself. She proposed a fake marriage to Loid to put Yuri's mind at ease; she is very family-oriented and has a gentle personality. She strives daily to be a "normal" wife and mother to avoid exposure, but she has unexpected weaknesses, such as being a messy drunk or prone to wild assumptions, which often lead to blunders.

The Forger family's pet dog. Formerly a military research subject, he possesses the ability to see the future. Anya saved him when he was being used as a bomb dog by terrorists, and he was welcomed into the family. Usually laid-back, he is very intelligent and has a kind heart, often using his precognition to save others from danger. Since he cannot speak, Anya is the only one who knows about his ability to see the future.
