Diary of Coby-Meppo is the second mini-series created as a side story on the title pages of each One Piece chapter.

Short SummaryEdit

In Coby and Helmeppo's cover mini-arc, the two become unwillingly involved in an escape attempt by Morgan and the bravery shown by the two earns them the respect of their superiors, and the attention of Vice Admiral Garp, who decides after seeing their bravery to train them. Coby and Helmeppo serve under the Vice Admiral Garp, at Marine Headquarters, as well as training to become stronger under him.

The story can be set between the events of Romance Dawn Arc and the end of Jango's Dance Paradise.

Long SummaryEdit

Coby and Helmeppo join the Marines, but find themselves doing a large amount of janitor work. Coby takes all the chores they have to do in stride, but Helmeppo does not, angrily stabbing a doll resembling Luffy. However, Coby continues to do his best in order to become a full member of the Marines, even studying hard during night hours.

The two are later tasked with chore duty on a ship transferring the prisoner Morgan, much to their shock. As they clean the ship's weapons, Helmeppo is worried about his father possibly getting the death penalty. However, Helmeppo later notices something shocking: the ship of the famed Vice Admiral Garp is coming. Garp prepares to take Morgan over to his ship, and Coby has to restrain Helmeppo. However, Morgan catches Garp off-guard and slashes him; taking Helmeppo hostage in the process. Morgan then escapes with Helmeppo on a small boat.

Quickly, the Marines prepare to fire at the small vessel to ensure Morgan's demise. However, Coby, not willing to let them kill his friend, scares them away with a gun. Bogard cuts Coby's guns into pieces, but Garps steps in before the two can continue fighting, claiming that he had been sleeping when Morgan slashed him. Meanwhile, on Morgan's escape vessel, Helmeppo finally makes a decision and abandons his father.

Helmeppo swims back to the Marine ship, where he, Coby, and the other Marines apologize to Garp for the ruckus and call themselves worthless. It seems like forever before Garp speaks, but after five seconds Garp decides to take the two with him. However, Coby and Helmeppo still have to do janitor duty at their new headquarters, but they still get to train in the night, only this time they do physical exercises. Back at their old headquarters, the girl they shared lunch with demands to know where they are, as Garp oversees his beaten and bruised trainees training.
