Demon Days Tatsu is the great grandfather of my fursona Infinite (and my av on SL, just crazier) anyway Demon Days is a sick twisted psycopathic killer and using the sword, then called "Blood Lust" he slaughtered his way to become the Blood Champion in the previous Blood Wars (if I right out the story you'll see for yourself) in a way he's also Infinite's 'devil's advocate'

(Oh and Happy Halloween ^_^)

He's always depicted as a cub because that was his prime, and when he became Blood Champion. He was finally killed off at the age of 19, but it took an entire town to do it... and not one of them survived the encounter. His lasts words in the world of the living were "Congradulations.... You've just brought down death incarnated..." And then died with a freakish grin on his face.
