Age of Discovery: The Invincible Swordsman of the Garp Family!

After transmigrating into One Piece, he becomes Garp's nephew and Luffy's uncle. He thought becoming an admiral was all but guaranteed, but then he found that fate seemed to be playing a joke on him.

His physique was even worse than that of some nameless recruit.

Fortunately, he awakened the Strongest Zanpakuto System, which lets him give his sword the abilities of any Zanpakuto.

Akainu: "Rogge's Ryujin Jakka nearly burned me to death!"

Hawkeye: "With Rogge's Lightning Blade, he can block my attacks with his eyes closed. I feel ashamed to call myself the world's greatest swordsman!"

Kaido: "Rogge is terrifying. One strike with his Kyoka Suigetsu, and every one of my men turned around and attacked me!"
