The time of reckoning is at hand... A brilliant final episode to provide stirring and emotional closure!

Upon learning the truth of her birth and the reason for the birth of half-spirits, Zakuro falls unconscious after being captured again. Meanwhile, Agemaki and the other members at Spirit Affairs dash off to save Zakuro, armed with the slightest of clues. With the guidance of Lords A and Um, they reach the Village of Oracles, only to run into... An extremely tense episode 12 which sets up the final stage.

The captured Zakuro was wandering an unfamiliar dwelling when she came across her mother, Tsukuhane. The moment Zakuro touched Tsukuhane, Zakuro was able to see her mother's memories that were previously unknown. Meanwhile, at Spirit Affairs, Kushimatsu was explaining what the Village of Oracles was and why half-spirits were born. As the final episode approaches, the truth of Zakuro's birth is finally revealed.

The members of Spirit Affairs make their way to a festival at the nearby shrine. Zakuro and the other girls are very excited in their yukata. The group first pays their respects to the guardian lions of the shrine, Lords A and Um, before enjoying the rest of the festival. They even try out the large maze that has been erected for the festival. The group breaks up into teams in a race to reach the exit, but Zakuro is captured by someone upon getting separated from Agemaki.

There is a fad going around where young girls ask a "kokkuri" for romantic help. Back at Spirit Affairs, Bonbori and Hozuki immediately give it a try. Zakuro and the others are also interested. However, the "kokkuri" runs off wildly. Zakuro tries to dispatch it but her blade has no effect. By chance, Lt. Hanadate, who came to Spirit Affairs with a request about this case, joins in the search.

It was another relaxed afternoon at Spirit Affairs when a young woman suddenly appeared and threw herself on Agemaki with a cry of "Young master!" The woman, Tae, was a servant of the Agemaki family who had been sent by the master of the Agemaki household, Kei's father, to Spirit Affairs. Agemaki reluctantly agrees to go home, but strangely enough, he begs Zakuro to come with him. Zakuro gave him an earful but agreed to join him.

The events of the military gala have left Ganryu in low spirits. Ganryu feels frustrated by his inability to do anything while Bonbori and Hozuki fearlessly protected him from harm. That is when Bonbori and Hozuki begin to tell Ganryu about their past― Meanwhile, Zakuro has been acting strangely since the gala, despite being her normal cheerful self. Kei appears to be the only one who has noticed.

Soldiers are allegedly being targeted by a spirit at parties and balls for government officials. Apparently, they're lured away by a woman who suddenly transforms into a giant spider. The Spirit Affairs team is in charge of security for tonight's military gala, per Lt. Hanadate Takatoshi's request. Zakuro and the others must dress in western clothing to disguise themselves as ordinary guests―

Spirit Affairs receives a request to investigate a suspicious piece of merchandise. Susukihotaru, Riken, Bonbori, Hozuki, and Ganryu head to the antique shop "Ori's" where the item is. The woman who owns Ori's, Orikata Aya, runs the place with the little spirit Mugi. The group is surprised to find spirit and human happily living together. Meanwhile, the suspicious item turns out to be a blade with an ominous aura.

A village mayor suggests they should hold a discussion regarding the occurrence of many young girls in the village being spirited away recently. Hearing this, Zakuro immediately becomes solemn and says to Kushimatsu that she'll take the job.

The Ministry of Spirit Affairs is up and running as human, half-spirit, and spirit begin an awkward life together. Zakuro is growing annoyed with the intrusion of Jesuit customs and the spirit-phobic soldier, Agemaki Kei, into her life. That is when they are tasked with conducting an inquiry into a spirit that's terrorizing the construction site of a western-style place of lodging known as a hotel. So Zakuro's motley crew of seven make their way to the hotel──

In this alternate history, the "Ministry of Spirit Affairs" was established by human and spirit representatives to deal with incidents involving spirits. Army lieutenants Agemaki Kei, Yoshinokazura Riken, and Hanakiri Ganryu have been assigned to Spirit Affairs. However, once they're introduced to their new associates, they discover that these half-spirits, with the exception of having ears on their heads, look like completely normal girls.
