Clients ? Now that was interesting . Carth had one more hunch he had about the man . He seemed almost scared and while that wasn ' t the best trait Carth was looking for , the more he thought about it , the more he was sure this man had something Carth could use . As Blake turns to walk away , Carth reaches out with one of his cybernetic arms and places it on Blake ' s shoulder . Right away , Blake felt his body go numb as he fell to the ground . Little did he know , the arm had seastone coating the fingers . Carth Ah , so you are a devil fruit user . Interesting . You were the one with the power to turn invisible yes ? I could use a man like yourself . Carth helps Blake up . He then pats off the dirt that accumulated on Blake from the fall . Carth Yes . since my departure from Gin ' s crew , I don ' t have the resources I once had . As it is now , I only have two crewmates . The Carthel is looking to expand . If you are who I think you are , you would make a fine addition for my operations .
