Premise: “The year is 1550 AD, Sengoku-period. It is a time of social upheaval, political intrigue, and nearly constant military conflict. Japan is dominated by local lords, known as “Daimyo”. One particular Daimyo, Nagiichi KAMIYA, has become the subject of numerous social uprisings and assassination attempts, due to imposing high taxes on the lower class farmers and craftsmen.”
“Neighboring Daimyo uses this as a means to extend their dominance by means of assassination. You’ve been hired as a mercenary for the personal protection of KAMIYA. You are a lone ninja, whose name is revered throughout Central Japan for your skill and abilities in the ancient martial arts known as “Ninjitsu”, gained from years of dedicated training. Should you successfully complete your mission, you will be greatly compensated for your time and skill.”
