The AI character chat service zeta announced that it would remove plots that used content belonging to rights holders, including nijisanji, without authorization. The number of items subject to removal and the completion date have not been disclosed, and the removal request is based on a rights-infringement notice from ANYCOLOR Inc.
The AI character chat service “zeta” announced that ANYCOLOR Inc., which operates the VTuber group nijisanji, had reported the unauthorized use of content to which it holds the rights and requested the complete removal of the relevant plots. The specific number of items subject to removal and the completion date have not yet been disclosed.
zeta is proceeding with the removal of the relevant plots in response to the rights holder’s request, but has not disclosed details such as the number of items involved or when the removals will be completed.
zeta is an AI chat service developed and operated by South Korea’s Scatter Lab. It was officially launched in May 2024 and, since standardizing its terminology around “plots” in March 2026, has provided story-based content created by users. As of August 2026, registered users in Japan exceeded 4 million, global users exceeded 12 million, and publicly available content exceeded 3 million items.
zeta has previously prohibited the unauthorized use of characters, and its official guidance permits only original characters. The removal request from the rights holder represents a specific application of that longstanding prohibition policy.
