Due to a recent spree of attacks by an escaped criminal, Hime Yarizakura begins to investigate the occurrences with her assistant, Kyōsuke Kishi. She enlists the help of Akina Hiizumi, Ao Nanami, and Kotoha Isone, who are preparing to welcome a new yōkai resident, Rin Azuma, a Jiang Shi, into Sakurashin. That evening, Hime confronts the criminal, Kosuke Yoshimura, who is holding Rin hostage, and Kosuke disappears when Hime attacks him. The following day, Kosuke holds V Juri F, a nurse, hostage, and demands that Hime comes to him. Hime does so and with Ao's, Kotoha's, and Kyōsuke's aid, they defeat Kosuke. Rin appears and holds Akina at gunpoint, revealing that Kosuke promised her revenge on the humans that abused her. Akina uses tuning to expel the yōkai from Kosuke's body, and when he offers to bring Rin to his office, she declines, claiming that she hates all humans.

Enjin demands that Akina open the entrance to the shrine, and Hime attacks him. Kotoha and Ao begin to fight Shinozuka, who manages to dodge all of Kotoha's attacks. Using the telepathic abilities of Gin's body, Enjin realizes that Hime is unwilling to seriously fight him because he is inhabiting Gin's body and overpowers her. Realizing that Hime cannot defeat Enjin, Yae decides to join the fight, but Mariabelle, Yūhi's assistant, reveals that Yūhi has forbidden her from interfering. Enjin forces Akina to open the entrance to the shrine by holding Hime hostage, and Akina does so. Yae throws one of her swords into Enjin's back, but allows him to enter the shrine, where he starts to force the tree to bloom. To stop the process, Hime uses the Dragon Spear to remove part of the tree.

Ao and Kotoha take a car and begin to search for the source of the yōkai energy that causes the Seven Pillars to grow, and Akina and Kyōsuke fight the yōkai appearing in the city. Hime attempts to leave the hospital to help, but Juri refuses to allow her to leave, citing her injuries. When she awakens later, Jinroku, an elderly citizen, gives her the head of the previous generation's Dragon Spear. As she leaves the hospital, she finds several townspeople who tell her that they want to fight the invading yōkai to save the town. Ao and Kotoha are nearly overwhelmed by the yōkai shadows appearing around them, but Yae saves them. Akina and Kyōsuke encounter Shinozuka and begin to fight him, and they are picked up by Ao and Kotoha, who reveal that the source of the yōkai energy is the tower in the center of the town. Kotoha conjures a railroad gun to attack the tower. Enjin goes to one of the Seven Pillars and forces it to bloom.
