On May 13, 2024, the Angels of Delusion faction (tentatively referred to as "Virtual Idols") was leaked by an unknown party through illegal means of obtaining development data, including character design concept drafts. Rather than cover it up, however, the official Zenless Zone Zero bilibili account opted to reveal the group in a blog post and explain details about it. The idea first came about from students on the production team who had a fondness for idol culture and how they believe it can give people strength, giving descriptions on the individual members: "a lead singer who wants to ignite everyone's enthusiasm with her singing, an artist who is born to be the focus of the stage, and a creator with delicate emotions and great talent." They also expressed interest in making real virtual idols based on the group once the designs were finalized, and creating related projects such as character songs around them. In a YouTube video uploaded on April 7, 2025, it was revealed that the faction would be coming to the game during Version 2.0.
