Sound Release: Sound of Waves

Onton: Chouon (音遁 潮音, Sound Release: Sound of Waves) is a technique that fires sound waves into the opponent's body instead of their ears. Doing so causes the opponent's blood to carry strong vibrations as it flows, resulting in the pummeling of their internal organs. This technique is very effective for assassinations, as it allows the user to beat someone to death without leaving so much as a trace of external damage to the body. As per its namesake, the technique creates a sound similar to that of numerous waves crashing onto the shore when performed.
