One Piece : Mysterious Journey
Shin Kazuma, a physics student in Tokyo, is deeply fascinated by the mysteries of the universe, time travel, and dimensional laws. During a complex experiment in his university's lab, a strange accident triggers a mysterious machine, which leads to his sudden transportation to the One Piece world.
He finds himself stranded in the vast ocean amidst pirate conflicts and the Marines. He quickly realizes that his body has changed, and he now possesses the rare Devil Fruit power called the Time Fruit, which grants him the ability to travel through time and sometimes return to his original reality in Tokyo. This power makes him a target for the World Government, which sees him as a potential threat due to an ancient secret that has been hidden for centuries.
While trying to understand his new abilities, Shin meets strong figures such as Luffy, Zoro, and Sanji, and gets entangled in maritime battles against the Marines and the Emperors of the New World. However, the challenges he faces aren't only within the One Piece world. He discovers that his original world isn't what it seemed—there is a secret organization in Tokyo that is watching him, aware of the One Piece world, and seeks to exploit his abilities for mysterious purposes.
As time passes, Shin begins to form his own crew, learning to master his Devil Fruit in combat and strategy. He becomes involved in key historical events within One Piece, uncovering secrets about the Void Century, Joy Boy, and the true One Piece treasure. His journey takes him to the past, where he witnesses glimpses of events that shaped the world, leading him to realize that he is not just a passive traveler but a central piece in the game of fate.
While his influence grows in the One Piece world, another threat emerges in his original world, as the machine that transported him becomes a target for governments and intelligence agencies. The plot evolves as the two worlds—his original world and the One Piece world—start to affect each other, placing Shin in a race against time to save both worlds from an unknown danger.
The novel blends action, adventure, mystery, and time travel elements, with the protagonist engaging in decisive battles, uncovering shocking truths about himself, and facing a life-altering choice: stay in the One Piece world and change the future, or return to his original world and protect what remains of his past life ?
