King Caesar x Reader

Your a 15 year old girl that used to be friends with a giant monster(or kaiju) that saved you when you were only 5. One a few people came to where the monster kept you. They took you and did something with the kaiju. Will they let you go back to see your friend? Or will you have to find a way to get back to him without them noticing?
This is my first book so if there is some stuff out of place or if I have to correct something. Please let me know. I will update the story when I get the chance. A lot of the art will not be mine, I'll let you when a piece of art is mine. All credit goes to the artists who made the pictures or art. But I hope that you guys will like it.
