The Ronin is made as an attempt to reenact the power-fantasy of being the protagonist of various films, made by Akira Kurosawa. The inspiration as to why the ranger was chosen, opposed to the fighter was mainly due to both the historical significance of the ronin's quest to demonstrate their skills across the country, as well as the romanticism of the wondering warrior, traveling across the lands.
