Maiyu's betrothed Heishiro is determined to go and protect her; while out gathering himself after being told no, he encounters Rasha'ou, one of the three Ninja Demons. He defeats the henchmen ninjas, but is captured by Rasha'ou's Shadow Binding technique. Rasha'ou takes Heishiro to an "Indian" circus, where he is hypnotized by an "Indian" magician using a metronome with a demonic figure at the end. Under Rasha'ou's orders, Heishiro encounters Maiyu, who is holding the Crimson Scroll. Heishiro asks to see it; when Maiyu produces the scroll, the magician uses Heishiro to hypnotize Maiyu and bring both back to the circus. The Scroll is fake, Heishiro takes the fury of Rasha'ou, and the magician offers to use the two as the means to get the real scroll. Akamine, Aokage, and Shirokage parlay the real Crimson Scroll for Maiyu. Aokage takes Maiyu out of the circus tent but is stopped by Heishiro, who attacks him. While Aokage is crossing swords with Heishiro, Maiyu grabs Aokage from behind, which leaves him open to being hypnotized by Heishiro. The hypnotized Aokage goes to Shirokage and hypnotizes him. Akakage then must fight not only Rasha'ou but his hypnotized allies. The hypnotized allies use their hypnosis upon Akakage, which goes into the gem in his mask and exposes the energy driving the hypnosis technique. Following the energy back to the source, Akakage is assaulted by various demonic images; Akakage, despite the assault, throws his kunai into the skull of the magician, freeing everyone from his hypnosis. Rasha'ou trades place with an armored warrior to escape with the Scroll; the armored warrior uses a lightning technique to burn the circus tent down.
