Kōun Ryūsui

Kōun Ryūsui (行雲流水, To Drift Like Clouds and Flow Like Water) is a powerful ninjutsu and an improved version of the Ryūsui, and was created solely to erase the terrible evil beings that the world does not need.

Usage
Accumulating Oxygen (O2) and Hydrogen (H2) from the atmosphere, Heiwa applies the erasive power of his eyes. Thrusting it into his opponents, any part that comes into the water, including the internal organs, loses form and turns into nothingness. This essentially makes it impossible to block with any physical matter and/or chakra-based techniques.
