SpiralAI is extending the chat-RPG format from one Atelier heroine to a second before the first app is a year old, and the stage numbers for RyzaChat:AI (15 million total utterances, over 100 million X impressions, top of the App Store free entertainment ranking) are the evidence the company is using to justify the expansion.

SpiralAI announced on September 18 that SophieChat:AI is in development, a free-scenario AI chat-format RPG set in the world of Atelier Sophie 2: The Alchemist of the Mysterious Dream. Players travel, synthesize, and fight by talking. The reveal came during a Koei Tecmo Games stage event at Tokyo Game Show 2026, held at Makuhari Messe from September 17 to September 21. Voice actress Yuka Aisaka, who voiced Sophie, demonstrated the development demo version on the streamed stage. The game follows RyzaChat:AI: The Story of Just One Summer You Create with Ryza, which SpiralAI launched in August 2026 under license from Koei Tecmo Games. That title slipped from its planned August 18 release to August 25 to strengthen servers after pre-registrations exceeded expectations. The same stage confirmed that the Ryza app will add skins drawn from new Ryza illustrations across the series, starting with a cheongsam and a Halloween skin.
SpiralAI is not licensing art from the Atelier games. The company states that all assets in RyzaChat:AI are drawn by hand under illustrator Toridamono, with no image-generation or video-generation AI involved, and that Ryza's voice comes from audio recorded for the project by original voice actress Yuri Noguchi and run through SpiralAI's own voice synthesis. Text runs on SpiralLLM, which SpiralAI developed in-house and trained on the scenarios and setting materials of Atelier Ryza. Conversation content is not used to train the model. Revenue is paid out as royalties to illustrators, voice actors, and the IP holder according to what was used.
The Sophie announcement did not come with a release window or platform details beyond the description as a free-scenario chat-format RPG. More Ryza skins are planned beyond the initial cheongsam and Halloween additions, with further drops set for December and January.
