KLab Launches AI Idol Group Capable of Music Creation and Game Streaming
KLab, a major Japanese mobile game developer, has announced an ambitious AI idol project that brings virtual performers to life in ways never seen before. The project, named Yumekairo Production, will debut on February 15, 2026, with a five member girl group capable of composing songs, singing naturally, interacting with fans, and even streaming games.
Next Level AI Performance
Unlike traditional virtual idols, these AI performers do not only follow choreography. During game streams, the AI is programmed to make occasional mistakes to mimic real human players, enhancing authenticity. On the music side, the AI learns from pre selected professional voice actors, analyzing vocal tone and phrasing to create new songs without requiring additional recording sessions.
Building the Idol Personality
Yumekairo Production has been in development since October of last year. The team gathers fan posts and feedback to train the AI personalities, ensuring the characters resonate with their audience. Leading the group is Yumemina Nana, a 20 year old character from Yamanashi Prefecture. She is gentle by nature but becomes passionate when pursuing what she loves. KLab aims to turn this project into a strong intellectual property for the future.
Producer Insight
Yoshiharu Kayanuma, the producer behind the project, pitched the idea directly to KLab’s president, recognizing AI as a transformative technology for the entertainment industry. He emphasized the growing importance of AI in game streaming and used selected Virtual YouTubers as voice models to teach the AI realistic singing and phrasing techniques.
Copyright and Voice Rights
Voice rights have been a major concern in Japan, as voice recordings are not directly protected by copyright law. KLab established clear contracts separating the AI training data from the voice actor’s identity. The recording process is fully transparent, providing a model for protecting voice actors’ rights in the AI era.
Industry Context
The timing of KLab’s AI idol initiative aligns with the booming subscription based digital market. In 2025, Google reported over $60 billion in revenue from YouTube ads and subscriptions, highlighting the potential for AI powered entertainment to generate significant revenue. KLab’s AI idols could open a new revenue stream similar to traditional idol fandoms, but fully digital.
Yumekairo Production represents a bold step toward AI driven entertainment, merging music, gaming, and fan interaction into one immersive digital experience.
