R: Odacchi! Congratulations! They're doing another One Piece movie. But this time, it's your script, right? I'm really looking forward to it!! ...and, when I was watching the movie trailer on my computer I heard the word "Kinjishi" come up - but isn't that the flying pirate who broke out of jail 20 years ago that Sengoku mentioned in chapter 530!? There has to be some connection, right!?
O: Yes. "Kinjishi". Actually, I really wanted to have his name come up in the scene where Shirohige talks to Shanks in volume 45. But I thought at the draft level that I was handing out too much information and confusing the readers, so I took it away - but in my mind, I have determined that he is one of the legendary pirates who played a big part during Roger's time. Though I didn't think I'd make a movie about him. In any case, "Kinjishi" escaped from Impel Down, and now that 20 years have passed, he's finally starting to make a move, and that's what the movie is about. There's an announcement on page 192.

I wonder what that announcement looks like? If it's that page with the Strawhat crew with shocked looks, I already have that picture.
