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.

Hime meets with Yūhi Shinatsuhiko, a tochigami, to discuss Rin's status in the city, and they decide to have her attend school and work in the city. Hime assigns Akina to be Rin's caretaker, but she quickly leaves. When she encounters Hime, she asks why Akina is allowed in the city, and Hime claims that Akina's tuning ability is necessary for the city's peace; however, Rin considers tuning murder. Elsewhere, Enjin Hiizumi, a wolf yōkai, attacks one of the Seven Pillars, the spiritual sakura trees that protect the city. Throughout the city, yōkai begin to lose control of their powers, and Hime confronts Akina, who is upset about Rin's belief that tuning is murder. Near Akina's office, Rin begins to lose control of her powers, and Akina uses tuning to expel the yōkai that was possessing her. The following day, a grateful Rin arrives at Akina's office to sell food.

Hime trains in her dojo with Kyōsuke, and recalls when her grandmother, the previous mayor of the city, died and left the title of mayor to Hime. At Akina's office, Hime starts to raise a dog named Silver, and determined to raise it well, feeds it ramen. After hearing a citizen comment on Hime's focus on raising Silver over her mayoral duties, Akina relates this to Hime, who claims that she can do both without complications. That evening, Silver goes into Akina's office and bites him. Furious, Hime hits Silver and he walks away dejectedly despite Ao's pleas. Enjin encounters Silver after attacking one of the Seven Pillars, and implants a yōkai into him, forcing Hime to fight him. After the yōkai gains control over Silver's body, Akina is forced to use tuning, which releases both Silver's and the yōkai's souls.

Akina and Hime discuss Enjin's possession of Gin Nanami, Ao's brother, with Yūhi, who claims that Gin's soul is likely destroyed. Elsewhere, Enjin realizes that he cannot use his full power because Gin's soul is still present in his body. Ao and Tōka Kishi, Kyōsuke's sister, prepare food for Hime on her business trip. When Akina searches for headphones for Hime, he finds a monkey statue that he won in a yakisoba-eating contest with Gin and Hime. That evening, Enjin attacks the barrier created by the Seven Pillars and passes through it. His associate, Eiji Shinozuka, is confronted by Kotoha, Ao, and Yūhi, who realizes that Shinozuka is a hanyō like Kotoha. Akina confronts Enjin, but is unwilling to use tuning on him after Enjin reveals that Gin's soul is still present in his body. Akina is saved by Yae Shinatsuhiko, Yūhi's sister, and Enjin retreats.

Hime returns from her business trip, and begins to broadcast a song of her own making throughout the city. Meanwhile, Akina meets with the Senior Council, which tells him to disregard that Enjin is in Gin's body. Afterwards, Akina meets with Yae, and tells her to keep his encounter with Enjin a secret. Hime, Ao, Kotoha, Kyōsuke, and Tōka agree to supervise a daycare center, but are unable to control the children until Ao uses her telepathic abilities to play with the children. When Ao reads the mind of Junta, a reclusive child, she accidentally reveals a promise he made with his missing father, and Junta runs away. Distressed, Ao refuses to use her telepathic abilities. Akina and Hime manage to find the boy's father, and Ao apologizes to Junta. As Ao relaxes on one of the Seven Pillars, she sees Enjin hovering in the sky.
