Nikyu-Nikyu no Mi is devil fruit that eaten by Bartholomeo Kuma, this fruit can be translated as Paw-Paw Fruit.
The power of this fruit are it can repelling any attack, or pain from our body as we can see in Thriller Bark arc when Kuma repelling the pain from Luffy. This fruit also can make other peoples flying for few days to somewhere place in the world.
What I'm ask here is what the reason behind a paw that can "repel"? Is there any myth or something that make this fruit named as Nikyu-Nikyu no Mi/Paw-Paw Fruit?
