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 disappears and Ao relates the incident to Akina, who asks him to keep it a secret. Enjin begins to experience pain as Gin's body is resisting him, and he leaves Shinozuka to do what he pleases. Kotoha is planning a trip to Germany and a karaoke party with her friends, and Hime asks her to be her training partner. During the training, Hime pierces Kotoha's airplane ticket to Germany with her spear. Furious, Kotoha conjures a 88 mm gun. Kyōsuke blocks the shot, and Kotoha apologizes to Hime. That evening, Shinozuka kidnaps Kotoha's friends, and lures her to the river. Although Kotoha attempts to fight him, he dodges all of her attacks, and attempts to convince her to join him due to the abuse she received from humans in the past for being a hanyō. Hime arrives, reminding Kotoha that she is a human to the core, and Shinozuka retreats.

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.

With the Dragon Spear, Hime begins to fight Enjin. When Akina arrives, however, he is still unwilling to use tuning on Enjin. Enjin travels to the meeting place of the Senior Council, and threatens to kill them. Yae arrives to fight him, but Yūhi tells her to allow Hime to fight him. Elsewhere, Kotoha fights Shinozuka, and after he overpowers her, Kyōsuke begins to fight him. After Kotoha distracts Shinozuka, Kyōsuke defeats him by trapping him behind a car. Hime continues to fight Enjin, who manages to cut her scarf using his scythe. In response, Hime uses the full power of the Dragon Spear to blow away all of the sakura petals on the Seven Pillars, and knocks Enjin into Akina, who uses tuning on him. Freed from Enjin, Gin thanks Akina and Hime before his spirit is sent back to the yōkai world. The following day, Akina repairs Hime's scarf and returns it to her.
