On Deep-Sea Prisoner's website, most characters have an official portrait and character number, the portraits and numbers of which are found on character sheets. Each character sheet contains 100 characters, with the first sheet containing characters with character codes from 0001 to 0100, the second sheet containing characters with character codes from 0101 to 0200, and so on.
This category contains characters that don't appear in any of the character sheets, have no character numbers, or official portraits. If a character on this category gains their own official portrait, their name will be removed from this category.
Characters appearing in illustrations, but don't have official portraits, count as characters not listed on the character sheets.
