The Demon Blade Marshal Who Began in Impel Down

The Demon Blade Marshal, beginning at Impel Down. The demon blade "Blood Fiend" kills automatically and absorbs 100% of its victims' power, including Devil Fruit abilities, turning it into demonic power. It then feeds 50% back to its owner, who absorbs it perfectly.

He arrives in the world of One Piece and chooses to become a lowly grunt at Impel Down. As the sole owner of the demon blade "Blood Fiend," the evil man known as "Demon's Flute Song" has one year before Luffy, Blackbeard, and the others invade Impel Down.

Ultimate goal: rise to the position of Fleet Admiral, take firm control of all the Navy's forces, sideline the World Government, and become the true ruler behind the scenes.
