As mentioned above Queen & Elizabeth serve as informants to Shotaro during cases. Queen is shown to have a tendency to eat food off a stick whenever it is in front of her. Elizabeth, as shown in Begin's Night, is known to have feelings for Shotaro's partner, Philip.

During the Liar Dopant case they ask for the Narumi Detective Agency's help when the judges of the Fuuuuuutic Idol competition are under the Dopant's deception. When the Liar Dopant is defeated Queen and Elizabeth get a major label release for their song, "Love♡Wars" but are disappointed when Shotaro and Philip got more publicity during their part in the competition.

During the events of Kamen Rider Double Forever: A to Z/The Gaia Memories of Fate, Queen finds the T2 Queen Memory, which can be used to form a barrier around the user. It attempts to take control of Queen and forms a living connector on her body. Fortunately Queen is able to resist and throw it away. Elizabeth also finds the T2 Accel, Key, and Bird Memories (a reference to the band the actresses belong to), and gives them to Shotaro without being affected by them.
