Having lost his father at an early age, young Rikuo Nura aspires to become the Supreme Commander of yokai just like his grandfather and late father did.
Ryuji Keikain uses his Shikigami "Gyogen" to attack Rikuo, who defends himself with his blade. Ryuji halts his attack when he recognizes the blade as "Nenekirimaru," a Spirit Blade that can only cut down yokai.
During the era when the Toyotomi Clan ruled Japan, there lived a young woman known as Princess Yo, who could heal any wound or disease with her magical powers.
Rikuo completes his training and returns to Ukiyoe Town with the Tono yokai. Seeing the progress his grandson has made, Nurarihyon allows Rikuo to go to Kyoto.
The Kyoto yokai are moments away from fulfilling their long-standing wish with only one seal remaining to break. Meanwhile, Rikuo and his clan members on board the Treasure Ship are about to enter Kyoto
