Katana Katana no Mi

Introduction
The Katana Katana no mi is a paramecia devil fruit that gives the user the ability to become a blade. Alright let me explain this now. The Katana Katana no Mi is a devil fruit that gives the user the ability to summon up a Katana. This Katana however is formed from the very soul of the user. This means that the blade is the user and the body is the blade.

When a person consumes the devil fruit there soul becomes a Katana and there is a connection made between the body and the sword. If the sword is knocked from the body hand it can be summoned back to it in a blink of a eye.

The body of the person who eats this devil fruit is no longer living. However it retains its original look and can both be damaged and healed. When one damages the sword the same amount of damage appears on the body. If the sword is destroyed then the body is destroyed. However if the body is destroyed and not the sword then the body can reform.

Usage
It should be noted that the user of this devil fruit can lean sword moves simply by seeing them. They are able to mimic swordplay at the snap of a finger.

Strengths
The user can live on even after there body has been destroyed. If the user body is completley destroyed the user can gain a new body by possessing whoever weilds them. The process is slow, but can be done over time. Once a body has been completley possessed then  the user can reshape it to fit there original body or leave it as it was.

Weaknesses
The user suffers from standard Devil Fruit weaknesses.

If the user body is completely destroyed they sword will remain. The sword however can not regenerate the body and will be stuck on the ground as a blade.
