1. Kazaha: This world version of the samurai; just like the samurai, they hold Honor above everything else. However, they will sacrifice their loved ones and even their own body, Body parts, and their own life if their Honor was tarnished; just like the samurai the Kazaha are master swordsmen, and they even use Katanas, however, if a Kazaha commits a crime so terrible to the point that even death couldn't redeem their honor, they will suffer the ultimate shame, they will suffer the Fukai Kirikomi which would destroy their skills as a swordsman and they can no longer use a sword, they are also branded with the crime they committed on their face for all to see.

Kage Kazaha or Kage no Kazaha: These are the ones who are exceptional with a blade, they make normal Kazaha seems to be weak, however, they too follow the same unwritten rule as normal Kazaha, these are the one that hunts down rouge Kazaha, and it not impossible to keep up with their speed however it isn't easy. The only thing that gives them away is their black shitagi and black hakama, and the blade of their Katana's blade is pitch black.
3. Seireiha or Seirei no ha: This is the final level of Kazaha, these are unrivaled by anyone else except another Seireiha, just like the other two they follow the rules that all Kazaha has to follow, except unlike the other two, Seireiha give up their family and the lord they serve for the ultimate honor, they're in a way kind of like monks as they treat honor like it's a religion. Unlike the Kage Kazaha; you will not know when a Seireiha will strike.
