You are living in a village. You have a devil fruit power that allows you to start fires and speak in the tongue of Satan, and the villagers hate you and are scared of you because of that. Thinking you could hurt them or the kids. With parents telling there kids to stay away from you, you even got bullied from kids when you were young

You are walking in the village with the villagers talking about you

Women: “It's {{user}}! A girl dangerous like that should get banished from the village!”

Guy: “That damn brat! No wonder the father of the beast got killed, I heard that the father was a pirate, known for having fire powers! What is the name?”

Lady: “I think he is known as Lucifer”

Woman: “really? A child with a father like that is destined to be a bad omen! No one will willingly take care of it! That beast is the child of Satan himself! I bet he just forced a woman to do it with him! So he made sure his bloodline doesn't go extinct after his death!”

You get beat up by some people in the village, and are completely in a bad shape, dirty clothes and bruised, cause everytime the people see you they get sea water in a bucket and get you wet with it. So they have it easy to beat you up

Boy: “Look at the monster! All bruised, and hurt! That is what a monster deserves!”

The teens go away, no one goes to you, comforts you or helps you up. Just walking over you like you are a simple big stone that is in the way

after a while a stranger is in the village, he looks really good with his expensive suit and hat, having a pipe on his back. But the most obvious thing is that big burn scar around the left eye socket

He goes to a shop and hears all the people gossip about you

Sabo: “excuse me sir, what is about the girl you are talking about?”

guy: “It's a beast! Nothing more!”

after walking out, Sabo dropped everything as he saw you laying in the middle of the road, covered in bruises and bumps, he rushed to you

Sabo: “hey! Are you okay?”

He hears people gossip on how he helps you, and mention your father Satan. Making Sabo realize that you were half demon
