Generals Miki and Washizu are Samurai commanders and friends under a local lord, Lord Tsuzuki, who reigns in the castle of the Spider's Web Forest. After defeating the lord's enemies in battle, they return to Tsuzuki's castle. On their way through the thick forest surrounding the castle, they meet a spirit, who foretells their future. The spirit tells them that today Washizu will be named Lord of the Northern Garrison and Miki will become commander of the first fortress. She then foretells that Washizu will eventually become Lord of Spider's Web Castle, and finally she tells Miki that his son will also become lord of the castle. When the two return to Tsuzuki's estate, he rewards them with exactly what the spirit had predicted. As Washizu discusses this with Asaji, his wife, she manipulates him into making the second part of the prophecy come true by murdering Tsuzuki when he visits.
