Plot
Rikuo Nura is 3/4 human and 1/4 yōkai, in which he has a human form in the day but transforms into his yōkai form at night. He lives in a house full of yōkai along with his yōkai grandfather. Trying to escape his fate, he does good deeds in order to avoid becoming a yōkai, despite his grandfather's wish that Rikuo succeed him as the Third Head of the Nura Clan. Rikuo is different because he helps humans. He eventually comes to terms with his yōkai blood and decides to take up the position of the Third Head of the Nura Clan. Multiple factions aim to stop him or usurp his position, and he must gather friends and allies, a new Hyakki Yakō under his banner of "Fear".

Storyline

 * Gyuki's Test Arc
 * The Kiyojuji Paranormal Patrol travels to Mt. Nejireme at the invitation of a supposed yōkai specialist. However, the invitation turns out to have been a trap by the head of the Gyuki Clan. Separated, the members of the Kiyojuji Paranormal Patrol must deal with yōkai of the Gyuki Clan and Rikuo ultimately faces Gyuki himself. Rikuo learns that Gyuki set up the trap because he didn't want the Nura Clan, which he greatly cherishes, to suffer under the influence of a weak leader. The two clash and Gyuki is overwhelmed by Rikuo's night form. Afterward, Rikuo decides to take up the mantle of Nurarihyon and officially become the next Nura Clan head.


 * Shikoku Arc
 * When one of the board members of the Nura Clan is attacked and killed, and Nurarihyon subsequently disappears without notice, the Nura Clan is thrown into chaos. Trying to keep them together, Rikuo encounters a rival faction from the Shikoku area who intend to take over the Nura Clan's territory. Their leader, Tamazuki, is ruthless and willing to sacrifice his subordinates to further his own goals. Rikuo and his Hyakki Yakō battle with Tamazuki and his Hachijuuhakki Yakō (consisting of 88 demons, instead of the 100 of a Hyakki Yakō) and emerge victorious. However, Rikuo decides to spare Tamazuki after the battle at the request of his father - who Nurarihyon had gone to visit. Tamazuki is spared under the condition that he build a memorial in honor of the subordinates who died by his hand.


 * Past Arc
 * The story of Rikuo's grandparents Nurarihyon and Yohime, the creation of the spirit blade Nenekirimaru and the battle against Hagoromo Gitsune 400 years ago.


 * Tono Arc
 * When Haguromo Gitsune resurfaces in Kyoto, Rikuo is determined to fight her and take revenge for his father's death - as well as rescue Yura, who has gone to aid the rest of the Keikain family in protecting Kyoto. However, as he is still too inexperienced and weak, his grandfather asks the head of the yōkai Tono Village to take in and train Rikuo. After an encounter with one of the Kyoto Yokai, Rikuo comes to realize what sort of power the yōkai Nurarihyon possesses and, having grown stronger, leaves along with several Tono Yokai to return to the Nura House and prepare for the assault on Kyoto.


 * Kyoto Arc
 * Rikuo, along with the vast majority of the Nura Clan and several yōkai from Tono, invade Kyoto. Nearly all of the onmyoji barriers around the city have been destroyed by Kyoto Yokai, and the Keikain House itself struggles to fight against Hagoromo Gitsune's forces. They ultimately join forces with Rikuo's Hyakki Yakō to replace the fallen barriers and stop Hagoromo Gitsune from giving birth to a new evil.


 * Hundred Tales Clan Arc
 * After the battle with Hagoromo Gitsune's forces and the resurrected Abe no Seimei, also known as Nue, Rikuo and the Nura Clan are challenged by the remnants of the Hundred Tales Clan and its executives. The clan was once led by a human named Sanmoto Gorozaemon who grew in power by spreading stories about yōkai and in turn created them. The group was destroyed by Rihan and the Nura Clan 350 years ago. Now, the clan is encroaching on the Nura Clan's territory and working to revive Sanmoto's main body, which resides in hell.


 * Gokadoin House Arc
 * Following the battle with Sanmoto Gorozaemon and his Hundred Tales Clan, it was revealed that the onmyoji sect known as the Gokadoin House is composed of Abe no Seimei's descendants who used Seimei's forbidden research on immortality to prolong their lives. When the Gokadoin house starts mobilizing to "purify" the land of yōkai and humans, Rikuo starts to establish an alliance between the various yokai clans throughout Japan.
