The 5 Core Principles Behind RyzaChat: AI! A World Crafted by Human x AI Synergy

Human artists handcrafted all visual assets in this title, while AI drives text and speech synthesis.
Here are the 5 core principles that RyzaChat: AI upholds in balancing human creativity and AI technology:
[Principle 1] Illustrations and Visuals are 100% Handcrafted
All visual assets for Ryza were handcrafted by artists under the supervision of character designer/illustrator Toridamono (@toridamono).
The team did not utilize any image- or video-generating AI.
[Principle 2] Voices: Original Voice Actor x Proprietary Speech Synthesis
Ryza's voice is powered by source recordings from the original voice actor, Yuri Noguchi (@yuri_nogu).
SpiralAI's proprietary voice synthesis technology powers the audio recorded exclusively for this app.
[Principle 3] Text Driven by Proprietary "SpiralLLM" Model
SpiralAI trained its proprietary SpiralLLM model thoroughly on all scenarios and lorebooks from the original Atelier Ryza series.
This AI model, SpiralLLM, generates Ryza's natural dialogue.
Designed with a privacy-first architecture, the model never trains on user conversations.
[Principle 4] Faithfulness to the Original World
The setting of Kurken Island, its map, characters, and lore strictly adhere to the original Atelier Ryza canon, built under the supervision of Koei Tecmo Games (Gust brand).
[Principle 5] Revenue Shared with Creators
To cultivate the AI character experience together with original creators, SpiralAI implemented a revenue-sharing mechanism.
SpiralAI pays a portion of all proceeds as royalties to the illustrator, voice actor, and original IP holders based on the assets used.
Comment from Yuichi Sasaki, President and CEO of SpiralAI Inc.
Rather than merely following a predetermined story, you create the narrative together through natural conversation with the character.
Throughout development, I was genuinely thrilled thinking, "How amazing would it be to experience something like this?"
It is a true honor to have the opportunity to realize this new interactive experience with Atelier Ryza, a beloved franchise with countless passionate fans worldwide.
I would like to express my sincere gratitude once again to Koei Tecmo for joining us in this new endeavor.
Please go ahead and talk to Ryza directly.
Depending on what you talk about and what actions you take, a unique story will blossom for every single player.
I sincerely hope you enjoy this completely unprecedented adventure.

PR TIMES
Introducing the Free-Scenario AI Chat RPG! A Playstyle That Evolves with Your Words

Without fixed rails, casual conversations with Ryza propel the story in RyzaChat: AI.
Whether you say, "I want to forage for materials in the forest today," "I want to learn a new synthesis recipe," or "Maybe I'll open a shop," Ryza responds accordingly.
Switch to RPG Mode when you want to progress the adventure, or Casual Chat Mode when you simply want to relax with Ryza.
You can freely choose how the two of you spend your summer depending on your mood.

Walking, gathering materials, synthesizing, managing your shop, and fighting alongside companions—every action on Kurken Island stems from your dialogue with Ryza.
In this free-scenario AI chat RPG, how you spend your days and how your adventure unfolds shifts with every word you speak.
Quest System

Early in the game, Ryza presents the initial quest: Build a boat to leave Kurken Island.
Players gather necessary materials while conferring with Ryza and synthesize the boat through alchemy.
Once the boat is completed, the world map unlocks, allowing travel to various destinations.
Inventory / Stamina / Cole System

The game tracks several core player conditions affecting the adventure, including Inventory, Stamina, and Cole.
By checking your status while chatting with Ryza, you can smoothly navigate the RPG experience:
- Inventory: Foraged materials, synthesized items, and quest rewards can be used at any time during dialogue.
- Stamina: Consumed during exploration and combat. Ryza checks your inventory and suggests recovery items or food.
- Cole: The in-game currency, needed when building boats, houses, and other structures.
World Map
Once the boat is crafted in the initial quest, the world map of Kurken Island—faithful to the original game—opens up.
Simply telling Ryza where you want to go moves you to areas where you can enjoy gathering, combat, building, and synthesis together.
Because each region features distinct materials and characters, enjoy exploring every corner of the map!
Characters
Set on Kurken Island modeled after the original game maps.
All original characters appear, delivering an immersive experience where you feel like you are truly living in the world of the original work through journeying, gathering, synthesizing, fighting, and building.
