A fantastically handled short story that sets up both an interesting character and provides many hooks for the universe as a whole. Fully embracing the Samurai style of the Dynasty gave them a lot of character (They even had a death Haiku!) and contrasts them well with the other factions they are fighting.
My only request would be if there could be a way to add a bit of clarity to the different time jumps. Just more for layout than anything.
Love it!
