Though parents worry over their children, the children themselves rarely realize. Seimei finds an exquisite item after a day of shopping around Touji Temple, only to have it stolen by a little brat! Raikou and Kintoki give chase and meet Gobeh.

With the book of magic, Onmyouryo, Kaguya prepares to cast the spell to seal Rudra while Seimei, Kintoki and the Gold and Silver knights physically attack the monster. Rudra begins absorbing the souls of people in the capital to increase its strength. They realize that Rudra is more powerful than before because of Douman’s influence and Raikou is sucked into its internal darkness. However he manages to bring the light of the Golden Knight into the darkness and enable Kaguya to seal Rudra and remove the Crimson Moon. In the aftermath, Douman reappears and attacks Raikou again but is defeated, and Seimei releases his soul, freeing him of the darkness that controlled him.
