Akki Odori/Honeju

Kossetsu is one of the five techniques called "Akki Odori".

Overview
The Kossetsu is a close-quarter combat technique, in which the user focuses their energy to their hand, punching into a certain target at a very high speed, fracturing bones with little effort.

It is a very useful technique that can connect fast. However it's meant to be on offensive it doesn't have any defensive manner, it’s probably because that it lacks maneuverability when striking.
