The townspeople of Sakurashin begin to prepare for the yearly festival honoring the Seven Pillars, and Akina and Hime, as the representatives of the Hiizumi and Yarizakura families respectively, are the key participants. In the ceremony, Hime carries the Dragon Spear into a shrine around one of the Seven Pillars and prays for the continued safety of the town. Following the ceremony, Akina and Hime join the party at Akina's office, where all the participants become inebriated on the alcoholic yōkai water. That morning, Enjin informs them that he has kidnapped Ao, and Akina, Hime, Kotoha, and Kyōsuke go to the shrine to meet him.

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.
