Jito Jito no Mi

The Jito Jito no Mi is a Logia-type that allows the user to control, manipulate and become cerebro-spinal fluid found in the brain and the spinal cord.

Etymology

 * "Jitojito" is an onomatopoeia for the sensation of being overly wet due to rainfall.
 * "Mizuke" means dampness.
 * In English, it is known as the Damp-Damp Fruit.

Strengths and Weaknesses
Its primary strength is to control the cerebro-spinal fluid which allows an illusion of mind control in which limbs of opponents cannot control themselves as their brains are seemingly "being manipulated by an outside force". However, it is also an advantage that the user is also intangible to non-Haki users as she can turn into this fluid even outside of her brain.

Its primary weakness however, is that it cannot control other bodily fluids such as blood or other liquids such as water. Other than this, there are no other known weaknesses aside from standard ones such as still water and Haki.
