Rikuo is in line to be the Third Heir of the Nura Clan, but has yet to assume the role. Everyone around him wants him to be the Third Heir, but Rikuo just wants to live a normal life as a human.
Zen, the master of potions who has always been like a brother to Rikuo, pays a visit to the Nura Clan, accompanied by his servant Hebidayu. Nurarihyon had invited Zen, seeking his help to convince Rikuo to become the Third Heir.
Yura Keikain, a new student in Rikuo's class, seems to hit it off with Kiyotsugu when they start talking about yokai. Kiyotsugu gets a little carried away and decides to start the Kiyojuji Paranormal Patrol to search for yokai.
It's been some time since Nurarihyon excommunicated the Kyuso Clan. Kyuso, the head of the clan,kidnaps Rikuo's classmates Kana and Yura and demands that Rikuo abdicate his succession to the Third Heir...
Rikuo develops a fever, and his classmates Kiyotsugu, Kana, and Yura pay him a surprise visit. Tsurara, who was taking care of Rikuo, panics when she sees Kana. But then, Kiyotsugu interrupts with an announcement regarding the Kiyojuji Paranormal Patrol...
Rikuo and his friends arrive at Mt. Nejireme, which happens to be the domain of a Nura Clan affiliate, the Gyuki Clan. The mountain is oozing with yokai energy, and Yura the onmyoji is not the only one who perceives the eeriness lingering in the air.
In the Heian period, Umewakamaru was born into a noble family. He was gifted young man exceling in fencing and academics. However, one day, he is informed that his mother is seriously ill.
When Gyuki crosses swords with Rikuo, he sees for himself the young Master's true power. Gyuki explains his decision to rebel and insists that he will no longer turn against the clan.
The Nura Clan enjoys a moment of peace before it encounters another threat. The new enemy is the mysterious yokai, Muchi, who wields a poisonous wind like a whip.
Nurarihyon is suddenly attacked by Muchi, but unfortunately, that is not the extent of the Nura Clan's problems. A young man by the name of Inugamigyobu-Tanuki Tamazuki reveals himself to Rikuo.
Gyuki's rebellion against the Nura Clan shook the foundations of the clan. But ironically, Gyuki's whole story is not one of betrayal, but of pain and loyalty.
Kagibari-Onna, one of the Seven Phantom Travelers, has infiltrated the Nura Clan by working as a waitress at Bakenekoya. But Yura isn't fooled by her disguise and informs Rikuo.
While Tamazuki prepares to attack, Kiyotsugu tells the Kiyojuji Paranormal Patrol that he has made a discovery from his yokai investigation. Someone has been destroying shrines all over Ukiyoe Town.
Natsumi Torii is the only person who continues to pay her respects to the local deity, Lord Senba. Natsumi decides to pay a visit to Lord Senba's shrine, but Lord Sodemogi is headed to the same place to continue his killing spree of local deities.
Upon destroying most of Ukiyoe Town's local deities and confirming the strength of the Nura Clan with Inugami's attack, Tamazuki decides to finally bring on the main assault on Rikuo's clan.
When the Nura Clan hears about the Shikoku yokai's attack on the Chichibo fortress, its members busily prepare to mobilize their small number of troops.
The great battle involving the Night Parade of a Hundred Demons has finally begun. Gozumaru and Mezumaru disguise themselves to try to get information about the enemy position.
The battle between the Nura Clan and the Shikoku yokai is slowly going in favor of Rikuo and his friends. But strangely enough, Tamazuki is still beaming with confidence.
