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 and Mamiru Keikain, two onmyoji who are powerful enough to take down even Aotabo, have arrived in Ukiyoe Town.

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.

In Kyoto, the Keikain seals are broken one after another by Hagoromo-Gitsune.

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.

At Fushime-Inari Shrine, Awashima the Amanojaku falls into a trap set by the Kyoto yokai 27-Faced-Senju-Mukade.

Having reunited with Yura, Rikuo is introduced to Hidemoto Keikain, the 13th Heir.

Rikuo is left severely beaten by Tsuchi-Gumo, when Gyuki arrives to take him to Mt. Kurama for treatment.

Hagoromo-Gitsune takes up residency in Nijo castle, having destroyed all eight of the onmyoji seals.

As the battle in Kyoto intensifies, the Keikain onmyoji and the Nura clan yokai realize that only by working together can they become a match against the Kyoto yokai.

During his training with Gyuki, Rikuo learns that by accepting his human side, and believing in his allies, he can become stronger.

The battle between Rikuo and Tsuchi-Gumo reaches its climax. Meanwhile, Nurarihyon enters Nijo Castle to confront Hagoromo-Gitsune for the first time in 400 years.
