pixiv Encyclopedia has updated the Privacy Policy as of May 28, 2024. Revision history
R-20 is tag used for items such as drinking, smoking, and public gambling, which are regulated by law for those under 20 years old.
Unlike other R-rated tags, this tag is not often used to express sexual or violent expressions (basically, it should be attached to illustrations featuring alcohol, tobacco, and public gambling), and it is not basically a restriction on viewing.
