Mato Seihei no Slave

As his school days draw to an end, Yuuki Wakura worries about his future. While lamenting the prospect of living an ordinary life, he is suddenly drawn into the world of Mato: an alternate dimension filled with dangerous monsters called Shuuki. Over the years since the existence of Mato was first confirmed, incidents of people accidentally wandering into the other world have become commonplace. To combat the threat of the Shuuki and rescue victims like Yuuki, the all-female Demon Defense Force was established. Its members have been blessed with the power of "Peaches"—Mato fruits that grant supernatural abilities only to women.

Though Yuuki's situation is dire, he is saved in the nick of time by Kyouka Uzen, the chief of the Demon Defense Force's seventh unit. Despite Kyouka's impeccable skills in battle, she has long been held back by her Peach-granted ability, Slave. Slave allows Kyouka to put a living being under her control and draw out its strength, but the Shuuki that she had enslaved until now had all proven to be exceedingly weak.

When Yuuki and Kyouka become surrounded by a horde of Shuuki, Kyouka resorts to something she has never tried before: using her ability on a man. To her surprise, Yuuki's slave form is much more powerful than she could have imagined. Believing the young man to be the key to unlocking her true potential, Kyouka invites Yuuki to join the Demon Defense Force—but not as a regular member.

Well, this was quite the ride if i do say so myself. The girls who straddled this anime's MC would say the same . Jokes aside, this anime was actually surprisingly good. And what i mean by that is the plot. Usually these sorta fanservice anime have a paper-thin plot. This one however has an actually intresting plot. The animation is allright, except for the CGI(obviously). And the fanservice is rather weak as well. The way powers work and all is also very nice,with all of them having drawbacks. With an exception here and there though.

So yeah, if you came around excited mostly for ... the fanservice... It's pretty scarce but it's decent when it does happen, so in that regard you might get dissapointed. But instead you'll be welcomed by a solid world foundation. A thing that i doubt anyone who watched it at first expected. A nice watch. Over and out.

Mixed Feelings

this review contains words that may not be suitable for some people, you are warned...
well well, Harem + Echii= this anime...
I really don't like this genre, so I started watching it with a contrary to my inner desires. the first scene was well done, it was like old samurai movies, when all of the village is burned, and it is in black and white, and we see the main threat massacaring everyone in the village, in a very brutal way. this scene is the best scene in the whole show, it is directed well, has good animation and it really delivers on selling you the ... main story point, about the villains and the main threat, so I give it a point.
but after that it was a cringe-fest of just the MC being miserable and acts like he has never seen a girl in his life, being one of the worst main characters I have ever seen, sometimes I don't know if Yuuki or Kyouka is the main character of the show.
the other characters are not better just some bland characters, with big Oppais and booty, except for Himari having a development and story for her-self.
the fan service is probably why you watched the show so let's talk about it... it is good, it is explicit really, they are really arousing.

in the end it is a harem, Echii series with decent story-line and bland characters, so the final rating for the show will be: 6/10

What is truly disappointing about this show is I really had high expectations for it. The premise seemed very interesting and the kind of original as well, and even seem to have some decent production value behind it.

Now that I have actually watched it, I am sad to say I was slowly disappointed. Not to sit here and complain all day I will sum it up by saying pretty much every character in the show is completely irredeemable and extremely annoying. The MC is probably the only character who is kind of okay, however he has absolutely no spine and never grows one. He ... acts all embarrassed during any scenes for the "rewards" or otherwise indecent moments. However, during the duration of the show he never becomes accustomed to it and continues to act surprised at every opportunity without becoming bold.

All the women in the show are completely despicable. They are all completely annoying to no end and full of themselves to the point I wonder if they were going to burst open. They all have great abilities and skills, but if you think about it for 2 seconds, they are stupidly dressed, overly pampered, completely self-righteous idiots who literally got their abilities by EATING A FRUIT and proceeding to act strong and as if they deserve to be showered with praise.

I have many other complaints but the plot is my other concern I will mention here. Far too much time is wasted on fan service and pointless moments, and the show is never allowed to proceed. We are never given a history on why these demons are invading Earth, where they come from, how long they've been there, and why they have to put a bunch of girls dressed in stupid military outfits who live in full-on resorts in the middle of this demonic world. Near the end of the show they tease there is going to be more, but it does not leave you wanting anymore and just thankful that it's finally over. I truly hope this does not get continued as it has no need for it.

TL;DR This is a poorly disguised harem anime with unlikable characters, terrible plot, and no real purpose or progression. Had it taken itself more seriously, it would be substantially better.
