AI Generated Content Disclosure

Declared by the publisher

Generative AI was used during development for certain supernatural visual elements and pre-rendered video sequences, and to assist with some visual design, UI, localization, code modifications, and limited narrative design. All live-action footage of Osaka Castle Park was filmed on location. No AI-generated content is created during gameplay.
