All Admirals: I Break Out of Impel Down from the Start

After transmigrating into the world of One Piece, Gerald discovers that he has become a pirate imprisoned in Impel Down, with a former bounty of 35 million Berries.

Luckily, he binds to a god-tier sign-in System and receives a very unusual Devil Fruit as a reward.

Five years later, with his Devil Fruit powers fully mastered, Gerald breaks out of prison in spectacular fashion!

Sengoku: "That man is the most vicious pirate in history, a heinous criminal!"

Dragon: "Gerald is dangerous. His ambition is no less than Rocks's back then, and he's even stronger than Rocks!"

Nico Robin: "He saved me."

Setting out from Impel Down, Gerald follows the Straw Hats' original route, signing in along the way and growing stronger.

Martial arts, swordsmanship, the three types of Haki, Devil Fruit powers, character cards, divine weapons...

His ranks are joined by powerful fighters from other worlds, including Uchiha Madara, Esdeath, Erza, Yasuo, and Irelia, all with Admiral-level strength.

Others, such as Kaya, Kuina, Nojiko, and Saka, gradually grow into fighters with Admiral-level strength as well.
