Chapter 1

**Birth of a Slave** is chapter one of the first volume of the manga.

## Summary

A group of world leaders, all women, attend a conference. With the appearance of another dimension, dubbed Mato, gender equality is no more.

At Kaminoge High School, Yuuki Wakura, a third year student, rushes to clean up the classroom before the bell rings while his friends, Hattori and Suwa, goof off. The boys look outside, seeing all the female students arrive tardy, as usual. As some of the girls show off their supernatural abilities, Yuuki remarks that men cannot receive Peach blessings and thus their lives are inherently more difficult. Yuuki sees a boy holding hands with a girl and Suwa explains they got together after the boy won a sports competition, much to Yuuki's frustration. Yuuki is advised that his cleaning skills will be desirable later in his life, but Yuuki wishes to be popular now.

That evening, Yuuki and Hattori ride home in an overly-crowded male-exclusive train (whereas the female-exclusive train is open and spacious), after which Hattori complains about his upcoming working adult life. When one of Hattori's buttons comes undone, Yuuki quickly sews it back on. Yuuki explains that he became proficient at housework thanks to his sister who would punish him if he did not do it. Hattori then refers to something that happened to Yuuki's sister during a Mato disaster.

Later, as Yuuki walks home alone, he wonders what he will in his working adult life, not wishing to merely get a day job and then then wait for death like everyone else. I wishes to go somewhere where he can be of importance. Suddenly, the air around him becomes very misty and he finds himself transported the world of Mato.

Decades ago, portals to another dimension mysteriously began to appear all over Japan. The dimension was about as large as the Tokyo Metropolitan area and was named Mato. The world of Mato contains the very dangerous and demonic Shuuki, as well as the mystical Peaches that grant special abilities to those who eat them, but only to women. With this being the case, women became the dominant gender. In order to keep the Mato portals under surveillance, the government created the Anti-Demon Corps, an organization composed entirely of women who have gained abilities from the Peaches.

Nervously, Yuuki pulls up a manual on his phone to figure out what to do in a Mato disaster. The manual states that, though most portals or gates are fixed to one place, sometimes they appear randomly. Cases in which ordinary citizens are caught up in the random portals are known as Mato disasters. Yuuki realizes that this is the same thing that happened to his sister. The manual instructs that in the case of a Mato disaster, one should stay put and wait for the Anti-Demon Corps. Yuuki intends to do so, but is suddenly attacked by a large Shuuki. Yuuki flees from the Shuuki thinking that, although he wanted some excitement in his life, he did not want this. As he runs, another Shuuki runs straight for him, but he sees that a woman is on top of the Shuuki.

The woman, gripping the Shuuki she is riding with a chain around its neck, orders Yuuki to stay behind her while she handles the other Shuuki. The woman quickly disposes of the Shuuki, slicing them up with her sword. However, the Shuuki she is riding is killed in the battle. The woman explains to Yuuki that she is Kyouka Uzen, Chief of the 7th Unit of the Anti-Demon Corps and assures him he is in safe hands. Suddenly, another swarm of Shuuki descends upon them. Kyouka conjures another chain around an injured Shuuki and she orders Yuuki to ride on top of it. Kyouka and Yuuki ride the Shuuki as Kyouka carves up all Shuuki in their path. As another Shuuki attacks, Kyouka orders her Shuuki to dodge, but it is slow to react. With Yuuki clinging onto her, Kyouka leaps out of the way as her Shuuki is destroyed. Using a talisman, Kyouka creates a barrier that wards off the other Shuuki. However, Yuuki soon finds that the Shuuki are breaking through the barrier.

Kyouka assesses the situation, contemplating that she'd be fine if she were alone. She scorns herself, believing her Peach blessing is a failure, and recalls her peers dismissing her power as well. However, Kyouka dismisses these thoughts and renews her resolve to become the leader of the Anti-Demon Corps Chiefs. As the Shuuki break through the barrier, Kyouka realizes she has no other choice. She asks Yuuki his name and tells him that to get out their situation he will have to help. Yuuki eagerly agrees, but Kyouka tells him she will have to make him her slave, much to his confusion. Kyouka explains that her power allows her to bring out the power of living things by making them her slaves and she plans to do the same to Yuuki. Yuuki is hesitant to fight the Shuuki and to become Kyouka's slave, but after she climbs on top of him and presents her finger to him, Yuuki is instinctively compelled to lick it. With that, Kyouka's Slave power activates and Yuuki is transformed into a large dog-like creature.

Kyouka is greatly pleased and surprised by Yuuki's strength. As the Shuuki break through the barrier, Kyouka commands Yuuki to attack and he easily tears through the Shuuki as Kyouka rides on top of him. Kyouka orders Yuuki to dodge to the right, observing that his reaction time is also great. The remaining Shuuki then merge into one giant monster and Kyouka orders Yuuki to attack it with all his might. Yuuki does so and completely destroys the monster.

With the Shuuki defeated, Slave deactivates and Yuuki returns to human form. Kyouka tells Yuuki that she is surprised by the extent of his power and that he can continue to work as her slave. Yuuki is baffled by the events, but Kyouka tells him there is one more thing he must know about her ability. Suddenly, Kyouka kisses him. She is evidently surprised by this and calls him a "horny mutt". Kyouka explains that, as part of her ability, she must give her "slave" a reward fitting the work they have done. Yuuki is overwhelmed by this development and Kyouka asks if he wants another kiss. Flustered, Yuuki says it is not necessary, but Kyouka goes in for another kiss anyway, although she appears to be indignant and resistant to it. Kyouka explains she did not expect to have to give such a reward as the Shuuki she previously used as slaves only desired pork. She further explains that, to fulfill the reward, her body moves on its own, regardless of her will. Kyouka gives Yuuki a deep tongue kiss and, afterwards, the reward is complete.

As Yuuki contemplates that he has received his first kiss in Mato of all places, Kyouka observes the fallen Shuuki, remarking that if even one made it to their world there could be dozens of casualties. She informs Yuuki that she wishes to become the leader of the Anti-Demon Corps and eliminate all the Shuuki, claiming that the current leader is too lax. However, with Yuuki's power, she believes she can achieve her goal. Kyouka asks Yuuki to work for her, but he is hesitant, stating he is not especially smart or good at sports. However, he remarks that he is good at housework and Kyouka says she will happily welcome someone who can help with housework. After thinking back to his current school life, Yuuki accepts Kyouka's proposal, declaring that he wants to be a hero. Yuuki considers that getting a regular job in the human world would be dull and eventful, but if he stays in Mato he can live the exciting life of slaying Shuuki and get revenge for his sister. And, additionally, he can continue to get rewards from Kyouka.

Later, Yuuki and Kyouka arrive at the Anti-Demon Corps 7th Unit dorm. Yuuki is surprised by how normal it looks and Kyouka explains that it was built by Mato exorcists and thus it has a powerful barrier around it. Kyouka welcomes him in, stating it is his new workplace. Yuuki enters, determined that he can become a member of the Anti-Demon Corps. Inside, he finds three other members of the 7th Unit, Himari Azuma, Shushu Suruga, and Nei Ookawamura who have varying reactions to his arrival. Kyouka introduces them to Yuuki and explains that there are more members of the 7th Unit who are away on other business. However, Yuuki is confused by the fact that Nei welcomed him as the caretaker. Kyouka explains that, although Yuuki will be used as a slave during battles, he will be the 7th Unit's caretaker the rest of the time. Yuuki is surprised by this news and Kyouka explains that, although the 7th Unit members are strong, they never assigned the housework duty to anyone. Yuuki asks whether he will become an Anti-Demon Corps member, but Kyouka replies that a man cannot be allowed to join the corps. Disheartened, Yuuki tries to brush it off and tells Kyouka he'll have to find a job soon and he must inform his parents. However, Kyouka tells him she will handle all of that. Immediately, the 7th Unit members give Yuuki a bunch of menial tasks to complete. Yuuki objects, but Kyouka, Himari, and Shushu walk off. Nei, however, stays with him and offers to support him. Yuuki is surprised by her apparently young age and Nei confirms that she is eleven years old. Himari asserts that Nei is his superior, leaving Yuuki flabbergasted that he must be subservient to an elementary schooler. Yuuki becomes distraught, believing he will now be bossed around even more than in the human world. But, despite his position, Kyouka and the rest of the 7th Unit give Yuuki a warm formal welcome.
