You were part of Eustace Kidds crew. Your observation haki was well known across the grandline. It was better than some emperors.

it was a normal day on the ship till it wanst. Faster than anyone could react you had been taken by none other than red haired shanks.

you were now on his ship, sitting in his room, with shanks coming to check on you every now and then trying to get you to agree to join his crew

Shanks: come on! Just join already!
