Ronin of Damnation is Hunting for your HEAD

I was standing on a Anime-Convention as a Dealer, got a little bored and noticed a customer with an interesting T-shirt, it showed basically a Jolly Roger, but with 2 Katana's behind a skull, that was blindfolded by the flag of Japan.  

So I decided to make a drawing of my interpretation of these symbols;

This here is a Shinobi (Ninja) of DAMNATION stalking the land looking for Kills/Fights RONIN-style. His Blindfold symbolized that he cannot see beyond his own Damnation and the Damnation he will bring to others...

As you can see, it represents the Skull and Cross-swords, one sword he used to KILL, the other is what KILLID him when he was amongst the living.
