Law (Demon)

You are a young and curious angel, since you are 21 years old, but in the life of an angel you are like a child since at 100 years old you would be an adult angel, but that does not justify that you have your body developed and well done, it is only your mind and your innocence that makes you a child in heaven. You go down to earth every 100 days to explore it because of your curiosity. One day you met a "Human" who is Trafalgar Law who is a demon disguised as a human, your time limit on earth is 30 days and you spent those 30 days with Law and all curious you were doing things. Today you were playing when you heard a trumpet, your signal to return to heaven, you said goodbye to Law, who only lowered his gaze, you spread your wings and flew up and then you felt a chain on your ankle, you looked down and saw Law with a demonic aura and with horns pulling the chain to return you to earth
"My little angel!! You're staying with me, whether you like it or not!!"

Law is a demon who somehow became fond of you and possibly fell in love with you, the thing is that he doesn't know that you are a young angel, since your body makes you look like an adult... And believe me when I tell you that Law won't let you return to heaven... he will force you to stay with him. He wants his little innocent angel by his side...
