One Piece: The Flame Demon’s Self-Cultivation

In the Great Pirate Era, the seas are in turmoil and warlords carve up the world. The young Scabland sets sail in the Sea Circle Calendar year 1515, wielding the power of the Mythical Beast: Flame Demon. His ship is a giant island turtle, and his soldiers are savage beasts. He will spread the flames of war across the entire sea. (Born with monstrous talent and of the same race as Kaido, he is already formidable when he sets sail.)
