The alliance needs Kate's information in order to succeed their mission on Dressrosa. But, due to past event unknown from the crew, Luffy doesn't welcome Kate like he should. Kate ended up working with them despite her hates for Luffy. Kate's past will slowly be reveled as the story involve and Law knows more about her than he tells. I suck at summary but come read it!
This is the "introduction of a stroy that I will never continue" and I want to share it. It's about Kate Hargreeves returning home after her father died. She met with her siblings after a long time and worry about one of her brohter Klaus. Kate's power is ice.
Set after Punk Hazard. In order to succeed Trafalgar Law asks for the help of an old patient he had to save, Kate. At first, the only things the strawhats crew know about are: she sails alone in the New World and in Paradise selling information, they need her for some reason and, their captain, Strawhat Luffy, doesn't like her and she doesn't like him. Not at all.
