Fuwa Fuwa no Mi

The Fuwa Fuwa no Mi is a Paramecia Devil Fruit eaten by Shiki. It allows him to levitate things, such as battleships and himself. "Fuwa" (不和) means "friction" in Japanese, while "fuwafuwa" means light, airy, or fluffy.

Strengths and Weaknesses
The primary strength of this fruit lies in friction, in which Shiki can control objects such as reconstruct non-living things and make it levitate. His ability to fly is because of his swords Outou and Kogarashi attached to his legs as seen when he escaped Impel Down.

The main weakness of the fruit is that the user can't make living things levitate. It is the same reason he cut his leg off and put swords in it. It is unknown if he could fly through levitating his own inorganic clothes. Other than that, the user is still affected by the standard Devil Fruit weaknesses.

Usage
The abilities of this Devil Fruit allows Shiki the power to control nearby objects, including ones as large as battleships. When used on Outou and Kogarashi, it allows him to levitate, which would give him a great advantage in combat, and theoretically enable him to avoid many different types of attacks with relative ease.

In addition, he has also used this Devil Fruit's power to manipulate the surrounding environment such as: fashioning stone, debris, snow, and wind into roaring lion heads.
