RyzaChat:AI launches in Japan — Ryza’s free-scenario AI chat RPG arrives on iOS/Android

SpiralAI and Koei Tecmo’s Gust brand provided the license and world assets, while SpiralAI supplied its in-house SpiralLLM model and proprietary speech synthesis to build the interactive experience. The company published five guiding principles for the title: illustrations and video remain hand-drawn, voice is the original actor combined with SpiralAI’s synthesis, text is generated by SpiralLLM, the original world is kept intact, and revenue returns to creators. SpiralAI also states the app’s AI is privacy-conscious and will not train on user conversations.

Gameplay centers on natural-language conversation with Ryza rather than traditional menus or button-driven commands. Saying things to Ryza can make your avatar walk, gather materials, craft items, run a shop, or trigger battles; dialogue choices create the quests and actions rather than fixed command trees. The app maps earned items and parameters from conversation to an on-screen UI: items you acquire during chat appear in your inventory for immediate use, Ryza will tell you what materials are missing and where to gather them, and stamina is consumed by exploration and combat and can be restored by asking Ryza to check your supplies and suggest healing food or items.

The in-game economy uses “Call” as currency; players can ask Ryza about building costs — for ships, houses and similar projects — and she will list required Call and materials. The app includes a world map of Kueken Island that players can move across freely, and every character from the original Ryza trilogy appears in the game. Voice actor Noguchi Yuri recorded a gameplay-first look video provided by the publisher; the title also uses original voice assets augmented by SpiralAI’s synthesis tech as described in the release.

Product details and platform info: RyzaChat:AI is available on the App Store and Google Play in Japan, with supported platforms listed as iOS and Android. Supported languages are Japanese, English, Portuguese (Brazil), Indonesian, Hindi and Traditional Chinese. The publisher is SpiralAI株式会社. The release notes that the Atelier “Secret” trilogy — Ryza 1 (2019), Ryza 2 (2020) and Ryza 3 (2023) — has passed 2.5 million units shipped worldwide as of 2025, and the Atelier Ryza DX bundle is commercially available on PlayStation 5, PlayStation 4, Nintendo Switch 2, Nintendo Switch, and Windows (Steam), with single-game and three-game bundle prices given: single regular edition listed at ¥6,380 (tax included) and the three-game digital bundle at ¥14,355 (tax included). The trilogy’s CERO rating is C.

SpiralAI CEO Yuichi Sasaki commented in the announcement that it was an honor to realize this new experience in the Ryza world and thanked Koei Tecmo for collaborating on the project; he encouraged users to try talking to Ryza because each player’s words and actions will shape a different story. The publisher also emphasized the five product principles and reiterated the privacy-focused design: conversation data will not be used to train the models.
