People in One Piece, Escape from Impel Down City at the Beginning

Decades ago, for a Devil Fruit, Os accidentally injured the Draco fleet. After a fierce battle with Garp and Sengoku, he was arrested and imprisoned in the large prison Impel Down City, and was imprisoned in infinite hell. As a time traveler, he originally wanted to wait for the day when the war came on the top, and take the opportunity to leave Impel City and see the light of day again. However, the system that was suddenly activated decades later brought him an unexpected surprise: "Congratulations to the host for acquiring the talent PYROBROIN immunity!" As a result, Os got rid of the "curse" that all Devil Fruit users cannot break and regained control of his Devil Fruit abilities! And the first thing he has to do is: jailbreak!
