SpiralAI announced RyzaChat:AI on August 4, 2026, an AI chat RPG licensed from Koei Tecmo Games and set in the Atelier Ryza world. It was scheduled for August 18 on iOS and Android, then postponed so the company could add server capacity after pre-registrations exceeded expectations, and it launched on August 25. Conversation with Ryza drives travel, alchemy, and battles, with RPG Mode and Chat Mode offered side by side.
The company built the app around consent from the people who made the original. Ryza's voice uses recordings by original voice actress Yuri Noguchi synthesized with SpiralAI's own technology, illustrations are hand-drawn under illustrator Toridamono's supervision with no image or video generation, and revenue returns as royalties to the illustrator, voice actress, and IP holders. Text generation runs on SpiralLLM, trained on the Ryza scenarios and setting books.
The rollout added a second title before the first was a year old. At Tokyo Game Show 2026 on September 18, Koei Tecmo Games and SpiralAI announced SophieChat:AI, set in the world of Atelier Sophie 2, with a development demo shown by voice actress Yuka Aisaka. The same stage confirmed that RyzaChat:AI will add skins drawn from new Ryza illustrations, starting with a China dress skin and a Halloween skin, both listed as tentative, with more planned for December 2026 and January 2027. A multiplayer mode for up to four players and a Travel Mode using a map of Japan are still at the consideration stage, CEO Yuichi Sasaki said.
On September 29 the company said it will change the specifications of RyzaChat:AI to restrict what users can enter, citing prompt injection attempts, with an AI model update planned for October. On October 21 it announced SpiralLLM, the orchestration model that grew out of RyzaChat:AI development. It picks specialized AIs and processes for conversation, long-term memory, game state, story progression, and consistency checks, and reconciles their output. SpiralAI says patents are pending on these function groups.

SpiralAI announced SpiralLLM on October 21, 2026, an orchestration model for entertainment that grew out of RyzaChat, the AI chat RPG it runs under license from Koei Tecmo Games since August 25, 2026. Instead of leaving everything to one model, SpiralLLM picks specialized AIs and processes for conversation, long-term memory, game state, story progression, and consistency checks, and reconciles their output. SpiralAI has filed patents on the functions.
Oct 21
SpiralAI announced on October 21, 2026 the launch of SpiralLLM, an orchestration model for the entertainment domain. The model bundles specialized AIs handling conversation, worldview reference through RAG, long-term memory, relationship understanding, status parameters, story progression and consistency verification. SpiralAI describes it as an AI game master, modeled on the game master of a tabletop RPG, that selects the right model or agent per scene and reviews generated output before returning a response. The company says patents are pending on these function groups. SpiralLLM grew out of development of RyzaChat: A Summer Dream Story Made with AI Ryza, a free-scenario AI chat RPG licensed from Koei Tecmo Games that began service on August 25, 2026. SpiralAI says the title handles voice and illustration assets through specialist creators and includes a mechanism to return royalties to IP holders and creators based on the material used.
Oct 5
SpiralAI said on September 29 that it will change the specifications of RyzaChat:AI, its licensed AI chat RPG set in the Atelier Ryza world, to restrict what users can enter. The company cited prompt injection attempts by some users and said it does not tolerate attempts to make characters say things contrary to public order and morals. An AI model update is planned for October.
Sep 18
SpiralAI and Koei Tecmo Games announced new content plans for RyzaChat:AI: The Summer Dream Story You Create with Ryza during a Koei Tecmo Games stage at Tokyo Game Show 2026. The free scenario-based chat-format RPG, available on iOS and Android, is set to add skins based on newly drawn illustrations of Ryza from across the Atelier Ryza series. The near-term additions are a China dress skin and a Halloween skin, both listed as tentative, with more skins planned for December 2026 and January 2027. SpiralAI CEO Yuichi Sasaki said a multiplayer mode for up to four players and a Travel Mode that uses a map of Japan are still at the consideration stage. Cosplayer Suzura, who appeared on the stage, proposed a hand-drawn demon-style costume design, and Sasaki said he would pass feedback to the development team.
Sep 18
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.
Sep 18
Koei Tecmo Games and SpiralAI announced SophieChat:AI on September 18, an AI chat app set in the world of Atelier Sophie. It follows RyzaChat:AI, the free-scenario chat RPG for iOS and Android built around Atelier Ryza, which SpiralAI developed under license from Koei Tecmo. The Ryza app launched domestically on August 25 and has since rolled out overseas. SophieChat:AI is in development.
Aug 26
SpiralAI launched RyzaChat:AI Ryza to Create Your Own One-Summer Dream Story on August 25, 2026, for iOS and Android in Japan. The free-to-play app, licensed from Koei Tecmo Games, is a free-scenario AI chat RPG set in the world of Atelier Ryza 1 through 3. Players talk to Ryza to travel, gather materials, synthesize, and fight, with no fixed script. The release was originally planned for August 18, but pre-registrations exceeded expectations, so SpiralAI delayed it to secure additional GPU resources for the real-time AI processing. Ryza's voice uses recordings by original voice actor Yuri Noguchi, synthesized with SpiralAI's own technology, and the text model is SpiralLLM, trained on all Ryza scenarios and setting books. Illustrations by Toridamono are hand-made, with no image or video generation AI. The app supports Japanese, English, Brazilian Portuguese, Indonesian, Hindi, and Traditional Chinese, with a global version planned. Revenue is returned as royalties to the illustrator, voice actor, and IP holders.
Aug 18
SpiralAI postponed the August 18 release of RyzaChat:AI, the AI chat RPG set in the Atelier Ryza world, citing higher-than-expected pre-registrations and the need to strengthen server infrastructure. A new release date will be announced once decided. The app, planned for iOS and Android, features free-scenario AI chat with Ryza.
Aug 14
SpiralAI will hold a live stream on August 18 to mark the release of RyzaChat: AI Ryza and Your One Summer Dream Story, an AI chat-style RPG licensed from Koei Tecmo Games. Yuri Noguchi, the voice actress for Ryza, and Famitsu Weekly editor-in-chief SAGA will play the game live on the Famitsu TUBE YouTube channel. The game is scheduled to launch August 18 for iOS and Android.
Aug 6
SpiralAI announced on August 6 that its chat AI app RyzaChat:AI, based on the Atelier Ryza series and licensed from Koei Tecmo Games, will launch for iOS and Android on August 18. The game is a free-scenario AI chat-style RPG where conversing with Ryza advances travel, alchemy, and battles. It offers two modes: RPG Mode for story progression and Chat Mode for leisurely interaction. The AI uses SpiralLLM, trained on all scenarios and setting materials from the original Atelier Ryza, and conversation content is not used to train the model. All assets are handcrafted under the supervision of illustrator Toridamono, with no image or video generation AI used. Ryza's voice uses recordings by original voice actress Yuri Noguchi, recorded exclusively for the app and operated via SpiralAI's proprietary voice synthesis. Revenue is returned as royalties to the illustrator, voice actress, and original IP holders. Alongside pre-registration, SpiralAI began a user survey with a deadline of August 17, asking seven questions about honest feelings toward free-scenario AI chat RPGs, future project candidates, and questions for an August 18 release live stream.
Aug 4
SpiralAI announced on August 4, 2026 that it will release RyzaChat: AI Ryza and the One Summer Dream Story You Create, a free-scenario AI chat RPG licensed by Koei Tecmo Games. The app is scheduled for release in August 2026 on iOS and Android, and pre-registration opened the same day on the official website. Set in the world of Atelier Ryza: Ever Darkness & the Secret Hideout, the game lets players advance travel, alchemy, and battles through conversation with Ryza rather than command selection. Players can switch between RPG Mode for story progression and Chat Mode for casual time with the character. The text AI uses SpiralAI's proprietary SpiralLLM, trained on all scenarios and setting materials from the original game. The project follows five stated principles: all Ryza assets were handcrafted under illustrator Toridamono's supervision with no image or video generation AI used, Ryza's voice uses recordings made exclusively for the app by original voice actress Yuri Noguchi, the world follows the original map under Koei Tecmo Games supervision, and revenue is returned as royalties to illustrators, voice actors, and original IP holders.
