Pirate Demon Supreme

The Devil Fruit that Nolan ate was somewhat special... Not only because this fruit is a veritable "devil" fruit: animal type, phantom beast type, human fruit, devil form, but also because after eating this fruit, it immediately turns into a growth flow system! Use the souls of living people as nourishment, convert them into skill points, and unlock your natural abilities! Aura of fear! The devil transforms! Overlord color and domineering! Navy Six! Everything is available within the system! Now, the road to growth has been paved, just waiting for Nolan to hunt enough souls... A deal with the devil!
