Action

On the Grand Line, power comes from Devil Fruits and Haki.
    But today, a different kind of terror washed ashore!
    A nameless drifter wakes up in a world ruled by pirates and Marines, carrying the bloodlust of another universe's greatest battle maniac: Zaraki Kenpachi.
    Whether they're awakened Devil Fruit users with world-ending powers or high-ranking Marine Admirals, everyone is another whetstone to sharpen his blade.
    In the Great Pirate Era, everyone is searching for a legendary treasure.
    He's searching the seas for an opponent who can make him feel the threat of death!
    "Enough talking."
    "Let's kill each other until one of us stops breathing!"
