2 people who has been teleported to the world of modern Japan even though they were from the world of One Piece stays over to do some research about the modern era but discovers everyone dissapears from the world(don't expect the book to be often updated I'm a lazy type of person 💔 and the fact it won't be as accurate as the main story cause like I said I REFUSE to rewatch 1 hour long episodes to remember the lines for a story)
