Trivia

 * Her Japanese name is "Seiko" (聖子), meaning "holy girl". This is derived from a transliteration of her English name "Holly".
 * Holly's Stand is the only one in the series to inadvertently cause harm to its user. Her stand is also one of the only 'Unnamed Stands' in the entire series and it has no obvious abilities (besides causing harm to its user).
