   Red Flame is a ruthless pirate ship captain and is one of the most feared pirate captains on the seas.
But when she was little her parents were murdered at her feet and she was left with her gandmother. Only her grandmother had fallen ill with a horrible sickness that could only be cured by a special root the Master Pirate guarded.
   When she went to retrieve it the Master Pirate thought she was a thieve and cut her legs of with is sword and used is elemental magic to send her back to where she came from.
   When she returned home her grandmother was already dead. With no one to take care of her she lived in an ally way eating the food people would drop, until a young girl who was one year older than her came to her and started to give her jewels and food.
    That girl was the Master Pirate's daughter, Taylor. The two girls became close friends and Taylor would come visit Sylvia everyday, until one day Taylor had to leave.
    So Taylor gave Sylvia lots of money so she could get auto-mail, (if you don't know what that is it's in Fullmetal Alchemist and it's body parts made of metal that is connected to the person's nerves so it's like and actual body part)
   Taylor also gave Sylvia a black necklace in hopes she would trade it for something, instead Sylvia kept it to remember Taylor.
Little did they know that when they grew up they would be bitter rivals. 
   Red Flame, who was once Sylvia, really wants captain Tsunami's ship, (Tsunami was Taylor) Tsunami's ship is the best ships on the seven seas.
   Every pirate tries to get it but fails except Red Flame who almost gets it.
