Shinobido: Way of the Ninja is a stealth-based video game set in old Japan featuring... well, Ninjas. It follows the story of Goh, the young and talented ninja from the Asuka clan, who suffers from a strange amnesia. Soon, he finds out that his clan was exterminated, with a few survivors, and the only chance of regaining his memory lies in some mysterious Purple Stones that contain fragments of his memory. In order to find them, he starts working for three powers (the Ichijo Clan, the Akame Clan and the Amurita Sect) in order to find all the purple fragments and find out what happened to him. He'll have to deal with rival clans, thick plots, two mysterious ninja who seem to know him well, and a masked evil sorcerer who's apparently after him.
