"After transmigrating to the world of pirates, Ryan becomes the lowliest shipwright's apprentice. His only wish in life is to fill his stomach.
That is, until the day the legendary Roger Pirates run aground on a deserted island aboard the badly damaged Oro Jackson.
With everyone declaring the legendary ship beyond saving, the "Dark King" Rayleigh at a loss, and the future Four Emperors Shanks in despair, Ryan hears the ancient vessel's unwilling wail.
So, right in front of the future Pirate King, Gol D. Roger, he reaches out and "heals" the ship that carries an entire era.
Roger laughs and invites him aboard: "Kid, join my crew! Let's turn the world upside down together!"
Looking at the bold man before him, Ryan knows he is destined for glory, and destined for death. This time, can he use his ability to hear the voice of all things to change that inevitable tragedy and give this era a different ending?"
Roger was not called the Pirate King until he arrived at Rafdrulu. No one else would call him the Pirate King before he arrived, okay.
The plot is really good, and it perfectly realizes the regret of Roger's illness.
