He's a quiet, philosophical man, a 21st Century ninja, a shadowy anachronism who routinely pits ancient skills against modern weaponry with absolutely brutal finesse. Common thugs, trained soldiers, armored tanks, combat cyborgs, rival ninja and all the demonic hordes his Dragon Sword can reach... nothing survives Ryu. Stealth isn't a component of the Hayabusa school of ninjitsu. Killing everything that moves, and then killing it some more is. Ryu Hayabusa is a thorough man indeed.
