One Piece OC - Roronoa Katya

This is a character i made up for One Piece after being away from the anime for a while and reading the manga's instead. She is supposed to be Zolo's cousin and she weilds 2 swords, not 3. She ate a cursed fruit which gave her the wings and the purple parts of her hair. I thought she could come in when the gang leave Roguetown, and she could land on the head of the Merry Go then Zolo would ask who she is. Anyone who can't read, it says "Don't you recognise your own cousin...'Swordboy'?" and the box says "Roronoa Katya, 'Two-Swords Katya'". Might do up on the computer some time if I learn a bit more. The necklace was given to her by Zolo when they were younger. Was finished on the 4th of December but scanner wasn't working then
