The Empire of the Moon faces many threats. The Rift has reopened, providing passage for the creatures that have lurked in Shadow for millennia. But the danger also comes from within as the Emperor, son of the Moon, is getting old, and his formerly loyal lords are now trying to seize power. In order to do this, they make their appeal to the warriors known as ninjas, adepts of the way of Shinobi. The clans are finally prepared for war!

As a lord with a thirst for power, in Shinobi WAT-AAH! you plan to place your honorable posterior on the imperial throne. In order to do this, you will appeal to the large clans of ninjas, who will enable you to impose your military strength upon your enemies.
