The Kika-Kika Fruit is a Paramecia-type Devil Fruit that grants the user the ability to manipulate sound waves. This includes creating, amplifying, and altering sounds at will, allowing for various applications such as sonic attacks, sound-based illusions, and even the ability to communicate over long distances through sound manipulation. The user can also create deafening blasts or soothing melodies to influence emotions. However, the fruit does not grant immunity to sound-based attacks, and the user must be cautious of their own abilities' effects on their surroundings.
