Plot
Rikuo Nura is part human and a quarter Youkai (demon). He lives in a house full of spirits along with his youkai grandfather. Trying to escape his fate of acting like a demon, he does good deeds in order to avoid becoming one, despite his grandfather's wish to succeed him as master of the Nura youkai clan. He eventually comes to terms with his demon blood and decides to take up the position of Young head of the Nura house. Multiple factions aim to stop him or overtake his position, and he must gather friends and allies, a new Hyakki Yakō under his banner of "Fear".

Terminology

 * Osore (畏) is term that denotes the unique skills and traits of each Yōkai. It refers to the "Fear" of the unknown, an emotional reaction produced when the Yōkai represent themselves as "monsters". It's especially important for leaders who wish to draw together gangs of Yōkai. There are different types of "Fear" depending on the species of Yōkai, such as water or ice. It also plays an important role in battles between Yōkai, in which they must "scare one another".


 * Hatsu (鬼發) is the first stage of activating "Fear", and is simply an attempt to scare an opponent by exerting a frightening aura. Those affected by "Manifestation" will experience an overwhelming sense of intimidation, and depending on their opponent's skills, may hallucinate. This aura produces a palpable wall of pressure in the atmosphere, and cutting through this tension to reach the enemy is an important part of Yōkai combat.


 * Hyoui (鬼憑) is the second stage of activating "Fear" used in Yōkai battles. It is the process by which a Yōkai materializes their "Fear" into an attack that can harm their enemy by severing their "Manifestation". Yōkai can produce a variety of attacks and techniques based on their type of "Fear".


 * Matoi is the accumulation of "fear" from Hyakko Yakou to the leader. It works only for a leader of part human part demon heritage, and it works by layering the Fear of the underlings on top of his own, exponentially increasing his power, as well as acquiring any sort of extra abilities into his power while using it. (when doing it with Zen his attacks were poisonous, when with Tsurara the attack froze its target.)The user also gets Tattoo-like markings on his back after first doing it with a new Yōkai.

Characters

 * Nura Rikuo (奴良 リクオ)
 * Rikuo is not an average 13-year old boy, his mother is Nura Wakana and he inherited 1/4 of his grandfather's youkai blood. In times of impending danger his youkai blood awakens and he switches into his night form to become the the Master of the Youkai(The master of all spirits). Destined to take over as The Third Master of Youkai from his grandfather. Rikuo once embraced the idea and played pranks on the other Youkai, but after realizing the evil nature of the youkai deeds he rejects the idea of becoming their master. He attempts to become more like a normal human by doing all sorts of good deeds, but he still appreciates his youkai underlings. After being tested by Gyuuki he decides to take the position of Young Head and saves both humans and Youkai.
 * He is seemingly weak but very clever, easily manipulating one of the council members into isolating himself during a meeting and rationalizing against the dissolvement of the Gyuuki Group. He can only transform at night or in darkness and reverts to normal in sunlight. Originally he couldn't remember things he did as his "Night" form, but he later is able to see and communicate with him.  Together they plan to form a "Hyakki Yakō" of their own.

 * Yuki Onna (雪女) / Oikawa Tsurara (及川 氷麗)
 * Yuki Onna is Rikuo's trusted attendant who follows him to school disguised as a normal school girl, known as Tsurara Oikawa. She is affectionate towards Rikuo, since she was jealous when Genjourou was embracing Rikuo as she was assigned to be one of the extra escorts, and when she saw Kana together with Rikuo (the day after her birthday). She also admires Rikuo's youkai form, because she finds him very reliable and magnificent.  She is overprotective of Rikuo when at his "day" or human form and expresses great concern for his well being, which is the reason why she is always around him at school (which causes a misunderstanding and concern for Kana). She also acts as the cook, though her food is delicious, most of the time it is chilled or cold.  As her name states she is a Yuki-onna.
 * She also has a fear of Yura, since she's a Onmyouji and a rivalry with Kana(going so far as to nearly freeze her)

 * Keikain Yura (花開院 ゆら)
 * An Onmyouji of the Keikan House who specializes in shikigami, she can manage four at once impressing even Nurarihyon. She was raised to see Youkai as evil and seeks to complete her training by defeating Nurarihyon and then inheriting the Household. After her brother reveals Rikuo as a Youkai and as Nurarihyon's grandson, she says she can accept it if it's him. She has returned to Kyoto to deal with the Hagoromo-Gitsune.

 * Ienaga Kana (家長 可奈)
 * Kana is the childhood friend and neighbor of Rikuo. She is hinted to have some affection for him, since she got jealous when she saw Yuki Onna/Tsurara alone together. Rikuo made a promise to help her if she is ever in need. After being kidnapped by a Youkai on her 13th birthday, she was saved by "Night" Rikuo and was taken to a Youkai party. In the next morning Kana asked Rikuo if he was friends with his youkai form and blushed when Rikuo asked why. She has fallen for Rikou's Night form.
