Batsu Batsu no Mi

The Batsu Batsu no Mi is a Paramecia-type Devil Fruit that allows the user to hurt their targets when they laugh.

Appearance
The Batsu Batsu no Mi appears as a very thin cylindrical fruit, dark in color with the usual swirl patterns. It is said to resemble the shape of a baton.

Usage
The power of this Devil Fruit is that it allows the user to harm their victims every time they laugh. They do this by selecting targets by touching them. Up to five targets can be 'locked on' at any moment. As long as the victims are targeted, they will receive a sharp pain in their backside as if being struck by a rod whenever they laugh. The pain can be enough to knock the victim down on their knees. Smiling is enough to trigger the fruit's ability. Victims can be held under this effect for as long as 24 hours at a time, or until the user releases them.
