Roland, an unlucky transmigrator, arrives in the world of One Piece without knowing its story. Still only four or five years old, he is abducted by a mysterious organization and subjected to hellish training, leaving him questioning his life.
After enduring it for five years, Roland, with the mind and soul of a mature adult, suddenly strikes back and brings the whole hellish operation crashing down!
From that day on, the changed and terrifying demon Roland returns to the world of the living!
