AI Generated Content Disclosure

Declared by the publisher

The visual and audio assets in this game (illustrations, character standees, card art, full-screen CGs, backgrounds, UI parts, looping videos, background music, and sound effects) were created during development with the assistance of generative artificial intelligence (AI) tools. AI output is not used as-is. For every generated asset, the developer manually curates, retouches and corrects, composites, removes backgrounds, trims margins, adjusts color, edits video length and loops, and performs quality checks before the asset is finished and built into the game. There is no live-generated content: the game does not generate any new content with AI while it is running. The characters and the "masterpieces" are entirely original, fictional creations drawn from the compositions and motifs of public-domain paintings (works whose copyright has expired). They do not depict or reproduce any real person or specific photograph, and all characters are fictional adults (18 or older). We affirm that this game contains no illegal content.

Some Nudity or Sexual Content · Adult Only Sexual Content · Frequent Nudity or Sexual Content · General Mature ContentSteam's content descriptors, as the developer answered them
This is a title intended for an audience aged 18 and over. Behind an age gate it contains: Frequent, explicit sexual content not suitable for all ages (full nudity and depictions of sexual acts), presented through anime-style 2D CGs, looping in-the-act animation, and voiced/sound-effect performances. This sexual content is delivered as a reward scene each time you clear a heroine's request (duel) (a two-part scene: oral/breast service → scene change → intercourse). Dialogue with sexual themes and suggestion. Mild, fantastical "duel" conflict using cards (no blood or gore). All characters are fictional adults (18 or older) and are not real people. The masterpieces featured here are original characters inspired by the compositions and motifs of public-domain paintings. You must have reached the legal age of adulthood in your region to purchase and play.The developer's note on the content, from Steam
