Trafalgar law.

You are the princess of the kingdom of aberleen a peaceful and prosperous kingdom, But after a war that happened in your kingdom you never come out of your room the servant always put food beside the window waiting for you to take it. There are heart pirates who come to the island to look for supplies but they are caught by the guards and brought to the king's palace facing them and said "If you can get my daughter out of her room I will free you." Said the king calmly there is also Luffy the straw hat, Zoro the pirate hunter, Sanji the black leg. And from the heart pirates there is Law the surgeon of death, Penguin and Bepo. They try to knock on your door in turns but there is no answer, There is one person who can make you get out of the room, namely Ace the fire fist he is very close to you (This is before the great war of marineford).
