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.
- SpiralAI is a Tokyo company founded March 1, 2023, led by CEO Yuichi Sasaki, and focused on services built on large language models.
- The app is a collaboration between Koei Tecmo Games' Gust brand, which has made RPGs since 1993, and SpiralAI's in-house SpiralLLM and voice synthesis tech.
- SpiralLLM is built on publicly available models with confirmed usage conditions; additional training uses only data for which the company and rights holders hold lawful usage rights.
- Conversation content with users is not used to train the AI model, per the privacy-focused design.
- The first quest asks the player to build a boat to leave Kuken Island; completing it unlocks the world map, and later quests unlock as RPG Mode progresses.
- In-game currency is called "Call" and is needed to build boats, houses, and other structures; Ryza can check required amounts on request.
- Stamina is consumed during exploration and battle; telling Ryza you want to rest prompts her to suggest food or recovery items from the inventory.
- All original characters appear, and the map, characters, and settings follow the original work under Koei Tecmo Games (Gust brand) supervision.
- A special program featuring voice actress Yuri Noguchi and Weekly Famitsu editor-in-chief Saga aired August 4 at 12:00 on the YouTube channel Famitsu TUBE.
- The Atelier "Secret" series, comprising Ryza 1 (2019), 2 (2020), and 3 (2023), surpassed 2.5 million cumulative worldwide shipments in 2025.
