Dedicated to a law of honor, pride, and dedication: without a Shogun, they seek to keep honor at the tip of their sword.
Honor though, is in the eye of the beholder. Working for the wrong side can be slighted if the chance of gaining honor is presented to this Ronin.
Money is made RED. Mercenary Ronins have rejected all form of honor in a collective manner, and will use every skill to whomever can pay them the most.
Unlike a Ninja, the code (The Code is bad Honor) of the Ronin is still valid..
And unlike a Ninja, even more, they don't bother hiding in the dark to kill you. They like the idea of the target seeing you as you kill them.
They won't kill women with children. Yet, mercenaries don’t like limitation on targets. They will break even the 4th wall to get you.
Rules are meant to be broken.
Many Ronin went back to kill off their former Shogun when disgraced and removed from their ranks.
They seek to serve no-one, and use what they have learned with a sword to gain power and ranks in other social structures.
Personal honor is still important to them. Without honor, they have no motivation to even get out of bed.
