Plot
Rikuo Nura, a kid that is part human and a quarter youkai (demon), lives in a house full of spirits along with his youkai grandfather.

Characters
Rikuo Nura

Rikuo is an average 13-year old boy. 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 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, but after realizing the evil nature of the youkai deeds, he now 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 (most of the time).

Nurarihyon 

Rikuo's grandfather. He is the first supreme commander.

Kana Ienaga (家長 可奈,)

Childhood friend and neighbour 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. In recent chapters, She has been putting together some of the weird traits and occurrences around Rikuo. She once again met Rikou in his youkai form in the last chapter after she discovered his glasses on the ground. In the latest chapter, she is being kidnapped by a demon on her 13th birthday. And once again Kana was saved by Rikuo in his youkai form, after she was saved she was taken to a resteruant owned by youkai. In the next morning Kana asked Rikuo if he was friends with his youkai form and blushed when Rikuo asked why. Which implies that Kana has fallen for Rikou's youkai form.

Yuki Onna (雪女/及川 氷麗)

Rikuo's trusted attendant who follows him to school disguised as a normal school girl, known as Tsurara Oikawa. She is affectionate towards Rikou, since she was angry when Genjourou was embracing Rikou 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 Rikou's youkai form, because she finds him very reliable and magnificent. She is overprotective of Rikou 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 are delicious, most of the time it is chilled or cold. She is really an ice youkai.

Kappa (河童)

A youkai in the Nura clan whose domain is the fear of water.

Kurotabou (黒田坊)

A youkai of the Nura clan.

Gyūki (牛鬼)

The kanji for his name means 'bull.' According to legend, he was once a human who died searching for his mother. His resentment led him to become a youkai after his death. He is a high-ranked subordinate of the Nura group. He was in charge of a conspiracy against Rikuo. It was revealed this coup was a means of a test, to see if Rikuo could handle being what he was and told Rikuo to abandon his human side as that would only get him killed

Yura Keikain (家長 可奈)

A young Onmyouji who came to Ukiyoe Town seeking the Master of the Youkai (Rikuo). She enrolled in the same school as Rikuo, as a transfer student from Kyoto. She has incredible talent for an Onmyouji despite her young age, since she is able to summon multiple shikigami. She has met Rikuo's grandfather, but has not realized that he is the Nurarihyon.

Natsumi Torii 

One of Rikuo's human friends and member Super squad investigation Kiyo
