Become an Iga ninja tasked with assassinating Nobunaga, undergo rigorous training, and fulfill your ambition to defeat him. This is a guide to "Iga Ninpo," which combines the fun of an RPG, where you explore various dungeons and defeat monsters, with the strategic depth of a Sengoku SLG (strategy game). I purchased this and have kept it since reading it once. There are no markings or writing.
