Sure is. Perfect Blue originated as a manga before being adapted into other forms like anime and films. It has gained quite a following over the years.
It's hard to say if there's a perfect one. A lot depends on factors like the art style, plot consistency, and character development. And these can vary from person to person.
There is a tale of a haunted mine in the Blue Ridge Mountains. Miners used to work there until a series of strange accidents happened. Now, those who go near the mine claim to hear the screams of the miners who died. There are also reports of seeing shadowy figures emerging from the mine entrance, as if still trapped in the place where they met their doom.
The writing style and tone could make it distinct. If the author of 'blue bloods a perfect oc fanfic' has a more humorous or darker tone compared to other fanfic writers in the 'blue bloods' fandom. The way the story is told, whether it's through a series of flashbacks or a very linear narrative, can also set it apart from other fanfics. And perhaps the author has a different interpretation of the 'blue bloods' lore, which is reflected in how they develop the OC and the overall story.
One key element is the struggle of the main character with her new career path. Just like in real - life situations where stars transition from one area of the entertainment industry to another, she faces difficulties. Another is the feeling of being watched all the time, which is very real for public figures.
Well, I haven't actually read this 'blue bloods a perfect oc fanfic' myself. But generally, in a good fanfic, the development of the original characters (OC) can be a great part. If the author has created a really interesting backstory for the OC and integrated it well into the 'blue bloods' universe, that would be a highlight. Maybe the relationships the OC forms with the existing characters in the 'blue bloods' world are also well - written, like interesting friendships or rivalries.
