Oto Oto no Mi (SR)

The Oto Oto no Mi (オトオトの実) is a Paramecia-class Devil Fruit that allows the user to control sound waves, making the user a Sound Human (音人間 Oto Ningen).

Abilities
The Oto Oto no Mi allows the user to control sound waves, which can be used to emit unpleasant noises, reduce unwanted noises, direct specific sounds at specific directions, and cause resonance.

Aside from that, the user is vulnerable to the standard Devil Fruit weakness.

Techniques

 * Sound Break (音破 Onha): The user emits a sound wave designed to cause resonance, which amplifies the oscillation of anything with an identical frequency. This can rupture internal organs, shatter bones, stone, and even steel.

Etymology
音 is Japanese for "sound."
