Adams, a transmigrator with a special physique, was initially thought to have a strange illness and came to Ohara for treatment. He became Robin's playmate as a child and awakened the potential of a king in an accident, obtaining a Devil Fruit with multiple abilities, comparable to a Frankenstein's monster.

With a special physique, the qualities of a king, and a powerful Devil Fruit, he decided to follow in Rocks' footsteps and become the freest person on the sea.

Is the Pirate King the freest person on the sea? No, even the Pirate King can be hunted and challenged. True freedom is doing whatever you want without any constraints.

This book tells the story of a time traveler who, following the fine traditions of his predecessors, does not eat beef and does whatever he wants.

(The protagonist's growth period is relatively long, but after growing up, the protagonist will do everything that Rocks did, and even more so. Please be patient, readers.)
