Mato Seihei no Slave Wiki
Advertisement


The first volume of the Mato Seihei no Slave manga.

Synopsis[]

The demon-filled dimension known as "Mato" has opened, and a type of "Peaches" tree that grows there yields fruit that confers special powers to those who eat it, giving humanity a fighting chance, but this only works for women. As such, as protectors of humanity, women rise in social status while men are relegated to second-class citizens scraping for basic occupation and acknowledgment. Cue Yuuki Wakura, a domestically crafty high school senior whose sister was taken during a Mato event 5 years before; while lamenting the hardships of the life ahead of him, an event opens before him, and while being rescued from demons by Captain Kyouka of the Anti-Demon Corps, she confers him powers as her "slave" and turns him into a mighty beast mount that mows down the monsters. However, there is a surprising price to pay for being her Slave... and it's not him who has to pay it.

Summary[]

In the year 2020, the concept of gender equality was no more with the appearance of gateways in Japan leading to another dimension, dubbed "Mato", where "peaches" from the other side endow women with superhuman abilities surpassing men in most categories. In consequence, women became the privileged sex, with affordances handed to them while men had to work especially hard. Decades later, Yuuki Wakura was a high school third year who spent time with friends and a skilled housekeeper since before his sister's disappearance. Yuuki was caught in a Mato Disaster, similar to the one that vanished his sister years before and was attacked by Shuuki, the Mato resident creatures. He is saved by Kyouka Uzen, Chief of the Anti-Demon Corps 7th Unit. But after Kyouka's enslaved Shuuki perished from an onslaught, and spurred by her motivation to be Commander of the Corps, she used her ability "Slave" to draw out Yuuki's inner strength and Yuuki morphed into his Slave form, able to supress the Shuuki horde hounding them. Once safe, Kyouka congratulated him before her ability's "reward" kicked in, whereby Kyouka had to give kiss him passionately, much to her embarrassment.[1]

After Yuuki reflects on his first kiss, Kyouka explains the threat of Mato Disasters leaking Shuuki back to Earth, and her goal to become the next Commander of the Anti-Demon Corps. With his Slave form drawing out her ability's full strength, Kyouka invites him to work for her. Although Yuuki starts to voice reticence, she interjects to espouse his mantra and goal of being a great houseworker, much to his shock. Not wanting a dull life, Yuuki wished to be a Hero in Mato, and also hoped following Kyouka could offer him revenge for his lost sister; with Kyoka's rewards would be proof of his growth. Brought to the dormitory for the 7th Unit, Kyouka's introduces her subordinate officers Himari Azuma, Shushu Suruga, and Nei Ookawamura. Kyouka clarifies that men are ineligible to be Anti-Demon Corps, and his role is their Caretaker, responsible for their base's upkeep while not a slave in battle. Dreams shattered, Yuuki attempts to excuse himself back to Japan but Kyouka grabs him stating she'll handle all that, as he is handed chores by the girls as they leave. Nei shows some kindness, but Yuuki is slightly dismayed an 11-year-old is his senior. Yuuki questions his choice, but Kyouka and the girls turn around to officially welcome him to the 7th Unit.[2]

In Japan, Kyouka settles matters of Yuuki's attendance at Kaminoge High School. Back in Mato, Yuuki is educated on Mato's size and where the other units are, but is dismayed to learn about inconsistent Shuuki activity, also earning some ire from Vice-Chief Himari Azuma before Kyokua reassures everyone that she'll discipline Yuuki. Once Nei foresees a new portal opening, they hurry over to guard from Shuuki, and save any wayward citizens. Once done, Kyouka hands Yuuki a candy for his little minimal efforts, and he cleans the barracks while questioning is he's needed. They are soon beset by a horde of Shuuki, and Yuuki resumes his Slave form to eradicate all Shuuki in the assault for Shushu and Himari to witness in awe. Exhausted, Yuuki is rewarded with candy orally this time by Kyouka before stripping, explaining her "reward" is linked to his base desires. She embraces him in her bosom while decrying him a pervert, as Yuuki feels his fatigue leave. Redressing, Kyouka explains her motives and her background as a survivor of the Mato disaster of the Gassan Oisawa incident, aiming to erase the Shuuki and avenge her town. Glad to have Yuuki beside her, he promises to help her anyway he can, and she orders he rest up. Later on, Yuuki overhears Himari and Nei playing in the open bath and averts his view in surprise. However, Shushu surprised him with a blackmail photo of him peeking, and extorts his being her slave to keep the photo quiet.[3]

Making Yuuki do her chores, Shushu teases him while showing some interest having never interacted with a male before. Too scared of Kyouka's wrath, Yuuki keeps quiet and is left alone with Shushu as the others leave for a meeting elsewhere. As Yuuki gives a massage, Shushu explains her sisters, her absent father, and attending an all-girls school, before playing a strip-game and laughing at Yuuki's manhood. However, they're interrupted by a goliath Shuuki attacking the base, so Shushu orders he stand back and uses Paradigm Shift to match the Shuuki in size, unaware of a concealed horde.[4] While Yuuki is amazed by her skill, Shushu is easily distracted to showboat and another goliath Shuuki blindsides her. Soon after, the concealed Shuuki merge with the second goliath to grow in stature and strength. Wanting to help, Yuuki recalls kissing Kyouka's hand triggers his slave transformation, and he rummages through her clothes to force trigger a partial transformation. As Shushu is about to shrink from exhaustion, Yuuki goes in for the finisher as she holds the goliath back. Reverting back, Yuuki lands in Shushu's cleavage and stands proud from the victory before covering himself realizing he's still nude. Seeing Yuuki so manly, Shushu's early opinion shifts from mockery to attraction. Kyouka later gives a reward regardless, and orders Shushu help Yuuki with chores, as she also took another blackmail photo from a compromising angle, not wanting to let go of her "Yuukey".[5]

Traveling through the 5th Unit's gate to Yamagata, Yuuki accompanies Kyouka on their shared day off, and quietly awes at her beauty. They board a women's train car, with Yuuki shocked at the space as she tells him to rest before they arrive. While he sees her ever-vigilance, he knows she brought him along as she's also visiting the memorial of her home town, where she gives a prayer and tells Yuuki what happened under a one-horned Shuuki. As the Corps logged said Shuuki as escaped, Kyouka swears to find and kill it in vengeance for her hometown. Before heading back, Yuuki invites Kyouka to a cafe for a parfait, and imparts her own wisdom that she take a break or she'll be too exhausted when her revenge comes. Appreciative, Kyouka enjoys the parfait before a signal on her phone alerts her to a potential emergency. Transforming Yuuki, they race back to Mato in record time and she rewards him by undressing her to change. They learn of a crater with a record high Shuuki horde, likely housing a nest and Kyouka rallies the 7th Unit to destroy it. Elsewhere, a Humanoid Shuuki senses Yuuki's presence in Mato, and decides to go see him. She is Aoba Wakura and she sits atop the one-horned Shuuki Kyouka seeks.[6]
