In Nightshade, the player plays as Hibana, a female counterpart to Shinobi's Hotsuma. She is a government-employed ninja tasked with the elimination of members of the Nakatomi Corporation, which has unwittingly unleashed hellspawn upon futuristic Tokyo. She is also ordered to recover the shards of "Akujiki", the legendary cursed sword that Hotsuma used to seal the hellspawn the last time. (wiki)
