Haōken

Flowing Punch is Hachiman's signature technique and a taijutsu technique unlike any other. It is so different from other taijutsu techniques that it is often called a ninjutsu technique.

Description
To use this technique Hachiman cups his hand near his right side with his fingers facing behind him. He flexes the muscles in his hand causing them to turn red with strain and it creates a spherical green aura between his hands. This green aura is the same aura seen when using the Eight Gates, meaning that it is made of sweat. The main difference is it is much more concentrated because of the small space it is in, giving it a more tangible form. The sphere is fired at high speeds when Hachiman thrusts his hands forward and opens his cupped hands. When the green aura hits the target it feels like they are being punched. The power of this technique can vary depending on how much Hachiman was concentrating.
