Place the game a futuristic Tokyo, where Ken (above its design worked Keiji Nakaoka, character designer Lost Planet), the protagonist of Ninja Blade, fights for the rights of ordinary Japanese samurai. Unlike Ninja Gaiden II, the arsenal of the protagonist fills all three weapons, among which you can switch in real time: katana (fast attack, which can be surprised the enemy), Souken (double swords, easy to replace nunchuck in battle) and Taiken ( heavy sword, used mainly against the foe with heavy armor)
