The violent rebellion and civil strife that have torn through the heart of 16th century Japan appear to be drawing to a close. Also coming to an end is the Azuma ninja clan's year of mourning in honor of the tragic death of Rikimaru. Alas, this long-awaited serenity may be short-lived. The mysterious Tenrai has begun a quest to conquer the country by amassing an army of ninjas and lords of darkness. Your master, Lord Gohda, has called upon you, a cunning stealth assassin, to stop Tenrai and his disciples before all is lost. Live by honor. Kill by stealth.
