Does Bonds of Yachiyo use AI-generated content?

Yes. The developers disclose AI-generated content on the game's Steam page:

AI was primarily used to generate initial illustrations that closely matched a desired image. These AI-generated images were then partially traced over to create line drawings, which were further refined through painting by the developer. The process involved not merely overlaying or editing the AI output but drawing from scratch based on the AI-generated references, ensuring that the final artwork, while AI-assisted, was significantly transformed by the artist's hand.
