A loose piece which got surprisingly much details and hints for the future.
He got CoC, which isnt shown now. He is on one of the most hyped islands ever, Elbaf. We still have no idea about his motivation, flashback etc. pp.. He is mentioned all the times when it gets about big numbers. He is one of the 3 main plot lines since beginning of Wano and we still have so much open for him. He is a loose piece right now, but Oda makes sure to keep him as piece in the story for a long time now.
