The game follows the player’s life alongside girls with unique abilities known as “Mates.” Players will work with the Mates to resolve various issues around Anima City while building relationships with them. The story will focus on their everyday lives as they live and work together. Several characters have been revealed so far. Minieh is an explorer who lives for the thrill of the ultimate adventure. Ohana describes herself as a genius all-rounder, while Shami is a cat-eared girl who is always short on money. The cast also includes Elevator Girl, a mysterious girl responsible for operating the elevators at Twilight Hall.

FAREIDOLIA was first teased in October 2024 as Project RX, which Nexon described as an immersive 3D anime game. The project is led by Min-seo Cha, who previously worked as a producer on Blue Archive. Blue Archive character designer YutokaMizu is also serving as the game’s art director. The game is currently in development for PC, mobile, and consoles. FAREIDOLIA is also scheduled to appear at Nexon’s booth during Tokyo Game Show 2026.
