The ability to go invisible has always been Kiara's escape from the real world since she was a little girl. Now, being kidnapped by the world's largest criminal, she has been told to use her deepest secret against the innocent city, Gotham; and fight The Dark Knight. Now, being held captive has made Kiara and The Joker spend so much time together to the point where they have come to the conclusion that they were never going to separate; well not separate again. What happens when The Dark Knight's cousin falls in love with Gotham's worst nightmare. Will they make unforgettable memories, late training and robberies to late night room visits; or will The Dark Knight separate them once again and make Joker's plan have an underground message as well? Kiara must choose love or family. But what happens if her safety brings the allies and enemies together, will there be a good ending to this dangerous love story and dysfunctional family? [I DO NOT-I REPEAT-DO NOT OWN THE CHARACTERS (JOKER, BATMAN/BRUCE, ALFRED, GORDON, HARVEY/TWO FACE, RACHEL DAWES, AND HARLEY QUINN) I ALSO DO NOT OWN HALF OF THE DIALOGUE USED IN THIS FAN-FICTION! CHRISTOPHER NOLAN IS THE OWNER AND MAN THAT OWNS THIS AMAZING MOVIE AND CHARACTERS! SO, CREDS TO THIS GUY) [I also changed the title after I saw this movie on Netflix called "irreplaceable you", AND I ABSOLUTELY LOVED IT! I learned something new about a fish! Mind you, the best and most romantic type of fish! It is also the scary fish from finding Nemo! Anyway, the fish is called anglerfish. The bigger anglerfish who is the female, swims all over the world until she finds a mate, she then lets the targeted mate/male (who is very tiny) bite her; and he doesn't let go. The two fish then conjoin as one, and die together. I hope you start to catch on where I'm going with this and see why it goes perfectly with the plot, characters, and their backgrounds :) Anyway, enjoy this fanfiction and thank you for coming to my TedTalk lol ]
