One Piece: He's Actually a Marine?

[Great Swordsman]+ [Rumble-Rumble Fruit]+ [No System]

Just after transmigrating to the world of One Piece, Harper eagerly prepares to set sail on an adventure, hoping to find like-minded companions and explore the secrets of the sea. Little does he know that a pirate with a bounty of just 8 million berries will become his nightmare.

The pirates' plunder leaves the entire town grieving.

Harper survives and joins the Marines, hoping to see the sea for what it truly is.

Gecko Moria: "Damn Marines! I'm a Shichibukai!"

Harper: "Oh? And what of it?"

After obtaining the Black Blade Shusui, Harper returns to Marine Headquarters at Marineford with the young Perona.

Zephyr: "Come here, little Perona. Let Grandpa hold you."

Gion: "What an adorable little sweetheart. You really are your big sister's darling."
