Mato Seihei no Slave

This show includes slavery, sexism, attempted rape, sexual assault, physical abuse, and blackmail; all in just the first 3 episodes. The protagonist is degraded and assaulted (verbally, physically, and sexually) regularly. One side character creates fake blackmail to force the protagonist to do the photo taker's bidding over fear of death if the photos were revealed to protagonist's master. The protagonist's master also threatens to mutilate their genitalia if they step out of line. There is sooooo much wrong with this show. Also, there is full frontal nudity, so it's basically a hentai pretending to be an ecchi anime.

Aside from the obviously horrible adult content, ... the characters are flat. The art is somewhat well done. The premise seemed interesting, a chained soldier, like maybe when changed they have to be carefully controlled or become a danger or something. But nope, the entire series is basically a giant kink fantast of abuse and slavery.

Aight, listen up. I'mma lay it down for you.



This series is based and respects the audience for who they are. People who like girls in sexy but formal outfits mixed in with a celebration of kinks and sexual desire played up in a fun way that end up well animated for the most part. Sometimes they add in a bit too much bloom and blur but it's fine overall cause the way they focus on that action such as tongues and lips GOING-AT-IT is just on-point. They don't hold back from any of the intimate stuff, you always know you'll be eatin' ... good when the rewards come out.

If you want something that will approach a variety of interests and desires that almost all people have, then you can find that they take various angles to include material or scenes that feature scenarios you'll like.

As a fan of the manga, the anime handled the inclusion of the "Reward" scenes without holding back on the good stuff which is always a concern when it comes to more ecchi portions. Especially with some of the tones that remain more hidden for now.

Is the animation superb? It's pretty good given this seems to be more of a risky venture. They're just trying to see how audiences react so it doesn't have a first-class budget.

Yuki also makes sense as a character for the world he grew up in and is respectable overall. The girls are fun and they only get better from here. Especially as you get to learn more about em.

Will you like it? If you enjoy lots of girls, some action, a variety of kinks and fun designs, yes.


It's targeted more towards men but I've known a few gals who love it too.

And to those who find themselves fond of such things. I say, "Welcome Home."

I read the manga a while ago. So obviously I was exited for the anime adaption. But after watching the first episode I can't say I like how it came out. The graphics and also the art style are just not it. Yuukis Slave Form doesn't look near as cool as in the manga, the fights and shuuki look awful :(
I also don't really understand the name, they should have stayed with the original: "Demon Slave". The name Chained Soldier doesn't really represent the show but hints something else which could cause some kind of confusion.
I think for me something is missing, it just doesn't ... feel the same.
After all it's fine and you can still watch it but I would still recommend reading the manga instead.

Well, the season of "I want to be a slave to Makima" has come to an end, the era of "I want to be a slave to Tenka" has begun, and femdom fans are back to their old ways....

If you know anything about the world of animanga, you probably know or have at least heard once about such a popular person as Takahiro, a man whose type I call an "idea generator". Takahiro is the author of several manga and short stories, including popular works such as Akame ga Kill! or Yuuki Yuuna Is a Hero. However, bloody fantasy and maho-shojo is not the only ... thing that this brilliant man can produce, because Takahiro knows all the delights that can appeal to readers, mostly Japanese. In 2007, for example, he co-wrote with Makoto Kanata the visual novel Kimiaru, a work where the story centers on a brother and sister who become the servants of three girls and, yes, yes, it's harem and ecchi, just the way we like it. Then, a year later, Takahiro took part in writing the script for the anime adaptation of the same Kimiaru from A.C.G.T Studios. And so, starting in 2019, Takahiro began releasing his ecchi shounen manga "Chained Soldier" in collaboration with artist Youhei Takemura, and then the announcement of an anime adaptation from Seven Arcs came out, with Junji Nishimura stepping in as director, taking a vacant slot between the two seasons of The Fire Hunter. And AT-X TV rewarded viewers with an uncensored screening of the show.

Yuki Wakura, the protagonist, has the unheard-of luck to find himself in another dimension filled with monsters ready to crawl out through the opening gates to the real world. In order to keep the real world safe from the threat, the dimension has created squads of female warriors who fight the monsters with their abilities, while living in the same world in their spare time as if nothing had happened. Wakura was in the middle of a gate and almost got killed, but Kyouka Uzen, the leader of the seventh monster-fighting squad, came to his rescue. She rescued him and made him a slave, recognizing his potential. After becoming a slave, the boy acquired the ability to turn into a large demon, supporting in such a state warrior girls as a reward for...erotic desires. Thus began the story of the slave Wakura, burning desire to fight monsters and the desire to become a hero with a lot of rewards in the form of sexy girls.

Chained Soldier is notable for the fact that it combines a lot of erotic moments, clearly dividing the line between an interesting plot and the whole vulgar part of the show. The picture is full of battles between the characters and their relationship with each other, and the fanservice desired by many remains as a cherry on this sweet cake. And the fanservice is really not based on the level of casual poses or showing underwear, but on various fetishes, I'm sorry, but I won't list them, you have to see it for yourself. The show also has a large number of female protagonists, among whom the brightest stands out a person with the name Tenka Izumo - a short-haired captain of the sixth squad, which, by the way, according to the results of the vote among readers took the leading place among the most popular characters of the manga. She is a cunning and charming girl who at first treated Wakura as a pet, not just a slave. And there are tons of such lovely characters in the show, as it's also a harem.

Seven Arcs and the animators are to be thanked for the spectacular and special effects, but still it was not enough for such work, especially the CGI graphics of the monsters in the second half of the anime, which apparently wanted to save the budget, but it turned out a bit crooked. Erotic scenes, in turn, shown in the adaptation are depicted worse than in the manga, although they appear in color with a couple of new angles.

Takahiro's manga can definitely be called ecchi with a good plot, while the adaptation by Seven Arcs can be understood as a good advertisement of the source material, which I, again, highly recommend to read. But still it's nice that the beginning of 2024 pleased us with ecchi shows, because the previous year was rather poor in this respect.

Over the past 12 weeks, I have spent a combined 4 hours of my fleeting time on this planet watching Chained Soldier, and through 12 episodes, all I can say is that my experience was only slightly better than taking the SAT, getting a colonoscopy, or having a physical done by an old man. This series just feels forgettable; in the depressing way where it isn’t laughably bad enough to be remembered, but it’s nowhere near good enough to be remembered either. This series is just another redundant entry into the bloated ecchi ___ genre, that blank being an amalgamation of different story beats that ... try to add more substance to the main plot of watching the main character be lusted after by beautiful women.

Kill la Kill is an ecchi anime that does this well; Its overall story is equal parts gripping and ridiculous enough to keep the audience engaged. Unfortunately for Chained Soldier, its story beats aren't strong enough to accomplish this. Chained Soldier goes for this weird Solo Leveling rip-off angle by establishing Mato: this mysterious shadow realm-esque location linked to Japan somehow. Unfortunately, Mato is hilariously underdeveloped as a setting.

As viewers, we only really know 3 things about Mato: one, that people can just wind up there somehow through a “Mato Mishap”, two, that there are peaches that grow down there that give superpowers, and three, the place is packed with monsters that the “Anti-Demon Corp” fights. This is absolutely everything that the plot operates on, so whenever Mato is treated as a “desolate wasteland” that impacts our characters or drives the plot, said character development or story beat usually is underwhelming, due to the sheer shallowness of the Mato. In addition, there is non-Mato-based character development, but it’s so bog standard that it isn’t even worth mentioning.

Mushoku Tensei is an ecchi anime that has very strong characters; Eris, Roxy, Cliff, and Sylphie, among others, are developed enough so that if the author decided to make a story featuring any of them as the protagonist, it would still have the impact of the main quest. Chained Soldier doesn’t even get close to doing that, as the characters are some of the most generic, trope-built characters anime has to offer.

For example, Yuuki is a black-haired self-insert mc whose key character traits are that he gets nervous around women and he has a generic “good boy” sense of duty. Kyouka is a generic tough leader who spends 90% of her dialogue saying leader shit, and 10% of her dialogue questioning Yuuki’s kinks. Shushu is a “teasing girl” who is really horny. Himari is a tsundere that initially doesn’t like men, but is now horny for our main character for…reasons. Nei is actually the only character that I have somewhat positive feelings for, only because she is a sweet distraction from the rest of the character cast. (Also I’m really happy she is not lewded in the story, as I really didn’t feel like making 20% of this review an explanation on why that isn’t ok.)

Keep in mind, those characters who might seem shallow are the “MAIN” characters of this story. The side characters are even more shallow; Tenka is just horny, albeit forcefully, and Azuma’s only memorable character trait is that strikes a Jojo pose to freeze time. I shouldn’t have to tell you that a character roster this bland and generic isn’t a recipe for success in any anime.

“So what if the characters and story are generic and non-compelling, at least we have the animation and fan service!” You might say that, however, unlike something like High School DXD, which looks good enough to be compelling as an action or fan service anime, Chained Soldier accomplishes neither. In fact, it looks like shit. Mato is this wasteland with a charcoal-esque ground and a reddish-purple sky. If that doesn’t sound visually appealing to you, too damn bad, it's the backdrop of every single fight that this show has to offer. Speaking of the fights, they aren’t animated well at all. Character movements often look chunky and cumbersome, like they deserve more frames to be fluid. Of course, that’s when the characters actually are in motion; this series uses a lot of animation tricks to avoid doing that as much as possible, i.e, sword slashes coming out of a charging character instead of animating them actually swinging their sword, and panning the camera instead of moving the character on a jump slash or something.

The art style of this show is just visually unappealing at times. Honestly, High School DXD, which was released 12 years ago, looks better in every capacity. The lighting is often strange whenever we are outside of the reddish-purple skies of Mato. Impactful moments are often defined with a chain flying across the screen, but these chains are so far outside of the show’s art style that they are jarring whenever they appear. And then the CGI, oh god the CGI. You see, all of the Shuuki, those monsters I mentioned earlier, are made through horrid CGI. Whenever they move, it is incredibly jarring, and it honestly fucks with any non-CGI aspect of the scene. This is even more disappointing for the more impactful Shuuki, who are imbued with special powers, thus having a different appearance, yet they have the exact same CGI movement patterns. Finally, the Shuuki don’t look good either; the basic ones look like Temple Run gorillas and the more advanced ones just look bad.

So… Chained Soldier is an ecchi “action” anime that fails to establish any sort of compelling story or characters. The show doesn’t look good either: the animation of the fights is bad, and due to the shitty art style, the ecchi fanservice isn’t fulfilling, and even if it was, it isn’t appealing enough to save the rest of the story. So, what does Chained Soldier do well? Well, other than not lewding Nei, not much. The biggest praise I can give this series is that it isn’t offensively bad in any department. Everything is mid to bad, but nothing is appealing, terrible, or anger-inducing. The only problem with this is that in the long run, Chained Soldier will just be forgettable. Hell, I’ve already started. I needed the MAL page for this series to criticize its characters, before referencing it, I only knew the names of two characters out of the entire story. I doubt I’ll be able to name a character in 2 months; in 11, I’ll completely forget that this series exists. And that right there, is a damn shame, because, on paper, this was something that could’ve been at least memorable.


Thank you for reading.

TL;DR: As a Manga reader, expected something like HS DxD, but got normie Harem plot with slow pacing. Animators not going full Degenerate level like other Ecchi shows do, and hence the overall experience is bad. Not recommended.


Okay, so I am a Manga reader, and I am reading this piece of art when there were only 15 chapters out, so yea, I am one of the OGs when it comes to the story and I know everything about the characters and what the story is about, so the whole anime is a huge L for me.

I was really thinking that this will be ... the next HS DxD or at least a tough contender, but it lost to a Magical Girl Parody and A basic Harem Isekai featuring Rings in Ecchi aspects.

Unnecessary censoring, no "Physics" like DxD/HS of the Dead and lewd scenes are glossed over. Pacing is also slow, when taking in the fact that S1 only has 12 episodes, aka 1 cour. We are already at episode 6 and we still don't have our top Girls of the story in with the MC, and I don't think my 2nd personal favourite (the Commander in Chief) will be in the Harem by the end of the season...

Well whatever, I had way, way more expectation, and it is sad that it was not met, Animation and Art is great, but just something is missing which DxD, To Love Ru and MahoAko has, I can't exactly pin point what... Maybe it's not degenerate enough, though Manga is recommended.

Welcome MAL users,this review is to answer all of your questions one by one that will clear your dilemma.
1. Can we watch it? Yes you can if you don't hate harem genre especially mixed in with the spice of ecchi tag.
2. Is it worth the watch? Well if you judge a book by it's cover, you will miss the contents of it whether it is good or bad and regret will occur when some other person tells you that you missed something you shouldn't have.
3. "It is for those people who have weird fetishes and for men who like to ... stepped upon and dominated" - some brainless randome user. HELL NO BRUH. You see, the title and the plot is based on the power of a girl Kyoka who can make any monster her slave in exchange for a reward of deepest desire and when she tries it on human(our MC), he changes into more powerful hero type monster but the condition is that his deepest desire for being a human teenage male is obvious (🌚) so the story revolves around that. I will not spoil the anime but as the story progress the rewards which seems(currently) to be for certain people, are slowly changed into something every human male desires. So please don't spoil viewers with wrong reviews and rating when you don't even know what's going to happen next.
4. What about CGI and action scenes? Believe me guys, either the quality of the action scenes and cgi goes up OR the amount of clarity on the ecchi and fanservice part of the anime gets a peak. If you watch this for ONLY action and adventure believing that Takahiro(Akame ga Kill) made it, you are in a middle spot; but as you can see from its genre and theme, if you are a man of culture then HELLO BROTHER-IN-ARMS.
5. Should we drop it? Brothers if you think that it will not worth it after watching those less weird 3 episodes, you will most likely miss that things which a fan of harem and ecchi genre loves the most that is:- FANSERVICE OF NEXT LEVEL WITH ACTUAL ROMANCE AND PLOT PROGRESSION.

This is my honest opinion and my first review so please be gentle on it. As for whether to watch it or not......


IT'S ALWAYS YOUR CHOICE🙋‍♂️

You know. I'm actually surprised.

When you first hear of Chained Soldier at first, you may be thinking of what an interesting concept, but as you dig deeper, you learn how things work, and it really makes you question what in the hell you signed yourself up for. Not to paint it in a negative light, as that wasn't the intention. But you throw in an interesting story base, interesting line of colourful cast of characters. Then you throw the most anime like thing into the mix, in terms of it's system of power. As if like the Powerpuff girls, you've got the perfect ingredients, then ... you add something extra by mistake. Which doesn't harm the show, far from it, more that this show will get odd looks at first, but then you actually watch it, and then you'll see that...

...It's not that bad.

Story and characters: 7
As stated in my opening, that I do feel where the show will shine most, is through it's colourful cast of characters. Each with their own fitting personality. Sure, it can seem as if each one just follows a common trope, which isn't surprising at all, but the contrast of meshing well together with each other, does wonders for the overall entertainment value. While I will admit, it is very weird. Very, very weird. But it can be a nice looking action filled anime, that'll give you enjoyment in this Winter season.

What will really take the kicker, is the story of Chained Soldier,and depending how the show goes, will be the make or break of this anime. At the start, I said I was surprised. Because you can read thoughts, or listen to opinions of what this product is about, but then you'll be pleasantly surprised that it's more tame than expected. Sure, it still fills that theme, and very much so. But if you may be expecting something over the top with it, it's not the case, which may make it more fine to experience, for those who aren't a fan of the genre even.

As for more inner details of the story. While it can be weird, but there are some daft moments in there,along with some interesting moments that'll more likely carry it to a solid success. While it won't be anime of the season. But is it a good story? I'd say so.

Art and sound: 8
I feel like this is also where it shines best. The colours really do suit the anime so well. Certain areas and themes will look smashing, where it be in a much more lighter context, or times where it needs a much more dark touch. The quality in this department clearly shows, and it shows good. Follow that up with a good quality of sounds, and you've got a show, that's good looking, and easy on the ears to boot. The sort of quality you want your decent seeming anime to be like.

Chained Soldier will be a hit for sure, not a massive one, but it'll make it's mark, and be one of the more better animes of the season, even if it's middle of the range. It's not massively impressive by any stretch, but it's a decent anime, that deserves a try.

🔵2024---When I first heard about this anime, I only knew that the author of Akame ga Kill had something to do with it and I thought I would give it a chance... I regret it

Unfortunately, this anime is a crap ecchi comedy with action elements.
So classic in this type of shit, empty characters and empty plot, these things are not important in this type of anime if the comedy, interactions between characters, action scenes and ecchi are fine but in this anime everything is so repetitive and boring that it hurts.

Mc is the most typical hero of generic ecchi action, a virgin ... without character but even more, the level of being a submissive loser goes off the scale.
This is the pillar of this series, the comedy of dragging the mc into mud and having it shamed by the female characters, for some it may be funny, for me it's embarrassing.

The eccchi scenes in this program are also weak and there are few of them for this type of anime, so even people who watch anime for the "plot" will not find anything here.

The action scenes that take up a large part of the episode are boring and the animation is hopeless, the fight with 3D idiots in the episode is not the least bit interesting.

After three episodes, I say that this anime is crap, which may be a little better in future episodes if the rewards from the white-haired waifu are "more interesting" XD
But why watch it? it's easier to type hen into google....

Gates to another dimension, called Mato, begin opening across Japan, where monsters known as Shuuki begin attacking the inhabitants of the Earth. Inside these portals are a resource called a "Peach", which, when consumed by women, give them supernatural powers, leading to a matriarchal society. One day, Yuuki Wakura, a recent high school graduate, stumbles inside a gate and meets Kyouka Uzen, the commander of the 7th squad of the Demon Defense Force. Kyouka has the power to "enslave" Shuuki and mount them for combat, but cornered by an increasing number of Shuuki, she asks Yuuki if she can enslave him. He consents and turns ... into her "slave", and they defeat the Shuuki. However, in exchange for using his body, she must give him an appropriate reward, often sexual in nature. Yuuki decides to join Kyouka's squad as a caretaker and support her dream of becoming the Supreme Commander, while fighting the Shuuki and discovering the mystery behind Mato.
HAHA RAPE=FUNNY because man+vulnerable=Funny!
Only good thing is animation tbh, but can't even have an unironical watch because the content ain't worth making fun off even if it was badly executed.
Reminds me of Serbian Film but at the least Serbian Film is hated, this is unironically praised.
Boring ass trash
Anyone who likes this should just watch porn tbh.

Chained soldier is a really bad ecchi with terrible story development.

For the characters, your MC is just an average virgin loser with barley any character to himself, his personality is probally the blandest and mundane of all and it just makes him super boring and painstaking to watch, the girls in Chained solider are just walking fan service, they also have a really average and weak background of "No one believed in me so I'm going to become super strong".

The animation is also hot trash in which for a 2024 anime adaptation is NOT good looks.

The fighting scenes of this anime aren't really immersive, ... it feels like the same thing over again and it's so poorly animated and you can tell at this pace it's going nowhere aswell.

Chained solider was just a cheap ecchi where you see a boy get bitched around by 4 other girls, the story is weak and the art is ass. It only took me 3 episodes to realise this and I don't even know how I got through the first two...

I'm assuming the only reason why someone would even watch this anime is because they had high hopes from the manga or they want their brain dilluted with over 15 minutes of fanservice in episode 2.

Meh. I was looking for more fan service than this, but it seems as the season goes on there is more and more actual plot, which is kinda mid. I think the monster villains were pretty cool, but there are alternative "neutral villains" and the basic monsters are pretty boring.

Also the girls running over the MC and making him clean and cook gets old pretty quickly. The MC almost always seems to be in a "male worker" outfit. I guess it's the main premise of the show, that the MC is a "slave", but in the combat scenes the MC seems to be a pretty ... important part of the squad, with the "slave" gimmick simply being a collar and the excuse for the "reward". They didnt have to make him a maid/cook too, but they did, and apparently he likes it and is very good at cleaning and cooking. He takes great care into this "not even a real member of the squad" role. I guess if you are an actual masochist, you might like this premise, but again not for me.

Like I said I came here for the fan service and the fact that even in the previews, the guy seems to be pretty powerful and the slave thing seemed to not be like a real actual slave but a power. In the end, while it is like that in the combat scenes, the MC is more than happy to become an actual servant in his off-time.

Overall I give it 6 for the fan service and cool, but barely shown, main villains.

With the beginning of winter 2024, we have quite a few adaptations. Most of them are successful at it, which Mato Seihei no Slave could not be counted in.
As a manga reader, Seven Arcs FAILED or decided not to use the mangaka's art style for the adaptation. This ruined the series from the beginning when the director made this decision. By any means, the art style is not bad, but you could say it tried to mimic that of a 2000s style, but in my opinion, it does not go well with this series.
The ecchi scenes are way more "mwehehe" in the ... manga than in the anime; this also goes for the characters and coloring.
If you want to invest your time in this anime, go ahead, BUT I recommend reading the manga as it is more enjoyable and actually makes you hard.

Ah, Mato Seihei no Slave, a tale where ecchi shenanigans meet the world-saving prowess of anime waifus—truly, a harmonious symphony for the discerning viewer. Now, allow me to paint you a vivid picture of my impressions:

In the grand tapestry of anime, there exists a realm where shallow ecchi plots frolic alongside almost-decent fights, akin to a whimsical ballet of predictable narratives. Enter Mato Seihei no Slave, where the world's defense hinges not on valiant warriors, but on anime waifus showcasing their formidable combat prowess. Our protagonist, a man in a sea of celestial femininity, is sadly devoid of battle acumen but excels as the ultimate ... househusband, mastering the culinary arts and domestic chores with unparalleled finesse.

In a peculiar twist of fate, our hapless hero finds himself enslaved by a sultry anime waifu. However, fear not, dear reader, for this is not a descent into the realms of hentai; it is a journey into the lewd, a tantalizing dance along the precipice of decency.

As our protagonist toils away, cleaning the waifus' base with unbridled dedication, a contractual clause demands a certain... amorous compensation for his efforts. A plot element that dances on the fringes of suggestive, inviting you to explore a world where lewdness meets power dynamics.

Now, should this concoction of ecchi escapades, battle sequences of questionable decency, and hints at a deeper plot tickle your fancy, then rejoice, for Mato Seihei no Slave might be your cup of tea. Yet, for a discerning viewer seeking substance beyond the surface, a lingering suspicion emerges—that beneath the veil of suggestive intrigue, the promise of a profound narrative may be but a fleeting illusion.

In the vast landscape of anime offerings, this one, my dear reader, is a niche that beckons to those who revel in the art of waifus, lewd contracts, and the curious interplay of ecchi and pseudo-deep plotlines. A realm where domestic prowess and sensual rewards converge in a dance of... well, perhaps not cosmic significance, but certainly of peculiar entertainment value.

Chained Soldier - Great manga with a stupid localization name, eager-but-turned disappointing adaptation, once again by Junji Nishimura, the long-standing director who can't hack a decent adaptation for time millennia.

If you know an author by the name of Takahiro, he's the creator who has created one of the most defining works of the 2010s: Akame ga Kill!. Anyone who've seen this show will tell you that it's one of the most popular shows of that time period, when anime was just about slowly going into the mainstream. And based off on one of the most prominent characters of that series, another work is created, and ... has undoubtedly become the author's next hit, which would become Mato Seihei no Slave a.k.a Chained Soldier (honestly, what a stupid localized name). And since this Winter season is where the cultured degeneracy amps a notch thanks to this and Mahou Shoujo ni Akogarete a.k.a Gushing Over Magical Girls, as a manga reader, I was expecting at least a somewhat decent adaptation to translate the well-regarded source material into anime. Sadly, that is where all my excitement is ripped to shreds.

The world of Mato Seihei is actually quite interesting, taking a fair few cues from and sticking true to the action-dark fantasy genre duo which Takahiro has become famous for since Akame ga Kill!. The dark-fantasy vibes, ranging from a dystopian Japan where gates to another dimension known as Mato began popping up out of nowhere, sprouts monsters known as Shuuki wrecking the inhabitants of Earth. To combat this, the resources called "Peaches", when consumed by only women, grant them supernatural powers to keep the Shuuki out of bay within reach from the portals. And it's where in one of these portals that the main MC Yuuki Wakura finds himself entangled into a Mato Mishap, only to find himself facing not just the Shuuki, but also Kyouka Uzen, the 7th Squad Commander of the Demon Defense Force. Fearing for the safety of his life, he consents to Kyouka's enslaving him to rid of the Shuuki, turning him into not just a capable chained soldier, but also a slave of which his power help aid her in revealing into her untapped potential. Of course, what's a slave without his reward, and that's where Mato Seihei ups the ante on the sexual innuendos, making it a defining trait of the entire source material. As Yuuki retains his standing in the Mato world as a caretaker of the 7th Squad to help Kyouka ascend in rank into becoming the Supreme Commander of the Demon Defense Force, he will find mysteries within the Mato world that connect dearly to him.

If you haven't noticed well enough, doesn't Kyouka Uzen resemble one of the characters in Akame ga Kill!? The eagle-eyed among you will realize that she is the embodient of Esdeath, and almost every inch of her character traits come straight from her, albeit a less tamed version when it becomes to the extreme. Together with Yuuki and the other girls of the 7th Squad: Himari Azuma, Shushu Suruga and Nei Okawamura, they're only a handful of what makes up the Demon Defense Force, all responsible for distinct areas where potential Shuuki may reside and appear from. As for Yuuki himself, he isn't a bad character, but he's kinda of bland, and by the appearance from the girls, a genuine caretaker to a literate power-up tool that like Kyouka, is able to take the girls' distinct powers to new heights, which at least makes him a valuable slave.

As for the girls of Mato Seihei, there have always been the competition for Best Girl of the series, and at least for the anime, we're blessed with a few standouts. Of course, Kyouka herself would be one, with the affinity of a clear level-headed leader, with Shushu being the clear next with her big assets, and both Himari and Kei looking up to Yuuki as just a companion within the small squad. Turn your head, and you have the 6th Squad members of leader Tenka Izumo, Himari's estranged sister of Yachiho and Shushu's match of Sahara Wakasa. Manga readers will already know that between the squad commanders, no girl has displayed as much rizz as Tenka, whom even in the face of trouble, still manages to assert her dominance, both to Yuuki and her enemies with her overwhelming Ame-no-Mitori space-time power, with an intellgent and exquisite mind-over-matter function. Anime onlies, now you know.

Sadly, the production of the anime has been the biggest Elephant in the Room, with Seven Arcs at the helm. I mean, I don't expect the studio to have good animation, but in my very humble opinion, the studio does not have the capability to handle action all that well. It's very foretelling that as the anime progresses, the reliance on CGI (especially for Yuuki's slave transformation and the Shuuki) becomes a necessity to combat the shortcomings from such an action-packed series like Mato Seihei. Sure, Seven Arcs may have done both the Trinity Seven and Magical Girl Lyrical Nanoha series, but both of those series are from the pre-2020s, at a time where animation wasn't the priority, but looking distinctive to stand out from the pack. Nowadays with so much sakuga going around, Mato Seihei just looks like a low-effort ball from people who don't understand how to make decent adaptations, and it all stems from one person: Junji Nishimura, whom in my opinion, is not the director that you want to lead a high-profile show like this. Even with the show being led by a new debut episode director of Gorou Kuji, there's just no saving the anime in this disappointing state that instead of being pumped for more action-intense fights, these battles just become boring as time passes.

The music is at least decent, though the OST is nothing memorable. At first, I wanted to like Akari Kitou's OP song, but it just felt so dragged out that the song becomes just as uninteresting as the visuals themselves. At the very least, Maaya Uchida's ED is somewhat in the realm of creativeness, expressing the 6 main and supporting girls, especially Tenka (since you already know the reason why she's featured quite a lot). The song, like the OP, is just borderline mediocre to fine.

As an AniManga fan, you know when your favourite source materials have anime adaptations that don't live up to the expectations, you're bound for a bad time, and that's my sole expression when it comes to Mato Seihei no Slave. Stick to the manga and forget that the anime existed, or just albeit willingly, try the 3-episode rule on the show if you intend to read the manga for yourself.

I don't get why all the hate.
It's an Ecchi Anime with good story and great Animation.
Yes there's slavery, blackmail, almost rape, forceful sences. But the MC likes that shit so i say it's okay.
But to be honest though the only girl with good character is Tenka's team.(Anymore would be spoiler but Tenka best girl)
If you want to watch Tiddies with high quality this show is for you.
(My rating would be an 8/10. I gave 10 cus people rating it low)
Extended review:
Animation: 8/10
Action: 7/10 (not bad)
Ecchi: 7.5/10 (They show skin but MC'S wired fetish isn't that erotic)
... Harem: 6/10 The character's aren't that good(other than Tenka)
Plot: 7/10 the story is somewhat good

Not a big fan of the story so far with the MC just being there and we go through how each of the female characters get their hands on him and develop some romantic feelings. The world building around MATO and curses was interesting at first. But, after a few episodes, i do not see much progress in the plot and is more focused on the MC interactions with the other female characters. The antagonists just get squashed like bugs. Gets quite repetitive and is a waste of 8 episodes so far.

However, lets be honest here, this anime is marketed towards a male audience ... and to sell those uncensored dvds. Anyone who was not put off by the NFSW slave + master premise knows what they are getting into.

Heck, id rather watch Highschool DxD again! It is much better in terms of SIZE, story and animation.

What the hell is wrong with this MC? Does he even have a backbone??
I think not. He just follows the orders and doesn't even question them. Very bad storyline. At least give a human personality to the MC and not some bs fan fiction.

The story was predictable af and not interesting at all. The characters look like have been the created by a chuuni who has a fking Masochist fantasy. -_-

Before watching, I thought that this was the worst anime this season, especially with the Echi and Harem themes which were definitely very boring.

But it turns out I was wrong! Indeed, for the first and second episodes I was quite no understand about this anime, especially in the story and background of the incident location, slowly but surely I started to understand that they were in a different world and were tasked with protecting there.

For Harem or Echi here it is still in a safe condition, not excessive, let alone making the audience horny, this is just my opinion, whether anyone else's.
This is different from ... the Ecchi anime that I often see, most of which show too much lewdness compared to the progress of the story, and this actually makes me disgusted to see it.
Indeed, this anime tells about slavery, but only that, there is no such thing as Lucky Sukebe, or a little bit of perverted things for no reason.
The MC himself is also not stupid, he is strong and has his own convictions, not easily tempted by perverted things.

In my opinion, the character design is quite good, perfect, not made randomly.
When fighting is also quite good, not stiff and not too much drama with unclear nonsense.

I also think comedy is funny, it even makes me laugh at some comedies, and this doesn't make me bored watching it.

The point is, don't judge something you don't know and don't immediately judge something as bad before you see everything.
I quite like this anime because:
The fighting action is good.
The characters are beautiful.
The MC is not bad.
Echi is not excessive.
This anime focuses more on story progress rather than perverted things.
In addition, there is a little romance too.

I'm not gonna lie, I came here just for the tits but I ended up finding a pretty interesting story.
I felt the anime had a nice balance of plot and PLOT.
I expected to not like it at first because being submissive isn't one of my fetishes, but the anime knew how to balance out the truly important bits.
As for the story itself, it seemed rather interesting. Nothing groundbreaking, sure, but interesting enough to make me pay attention to more than just the lewd scenes.
Honestly, if this anime doesn't get a second season, I'm considering going to the manga.
