The chapter begins with some students discussing a rumor about Ukiyoe Middle School having an old school building, where spirits supposedly run amok.
Meanwhile, at the Nura House, Karasu Tengu informs Rikuo that the world is in a yōkai boom and urges the latter to take up leadership of the Nura Clan already. When reminded of the events from four years prior, Rikuo shouts that he doesn't remember anything about them and Nurarihyon adds that at this rate, he'll die before Rikuo takes over his position. Rikuo, however, is very adamant about living his life as a normal human and leaves for school after discouraging several Nura Clan members from turning up around the neighborhood.
While walking to school, Rikuo mistakes the approach of Kana to be that of Karasu Tengu but is saved from having to explain himself by the appearance of Shima, asking for the homework Rikuo had done for him. Upon entering the classroom, Rikuo and Kana are greeted to the sound of Kiyotsugu explaining how yōkai do, in fact, exist. When he mentions his childhood savior and subsequent desire to meet him again, Rikuo inwardly hopes that Kiyotsugu never finds out that that "savior" was him. Kiyotsugu talks a group of students into investigating the old school building with him, and thus Rikuo finds himself waiting at the base of a hill with Kana, Kiyotsugu, Shima, and two previously unknown students named Tsurara and Kurata. As the group traverses the building, Rikuo discovers that it is home to a large number of yōkai and manages to repeatedly prevent his classmates from encountering them. Entering the last unexplored room, the group stumbles across a trio of yōkai eating an animal carcass, and the yōkai immediately attack. While Kiyotsugu and Shima faint from shock and Kana shuts her eyes in fear, Rikuo panics about not being able to protect his classmates after all - until a familiar voice brushes past him. He is surprised and then horribly confused at the sudden appearance of Yuki Onna and Aotabō, who defeat the attacking yōkai easily. They then reveal themselves to have been the two students from earlier, and tell Rikuo that they have been accompanying him in that fashion since the events of four years ago.
