Gate - Jietai Kare no Chi nite, Kaku Tatakeri

At times good, at times not so good. Some things are well thought out while others are quite childish or dumb. I like for example the way the author tries to balance Japan's policy regarding the gate and their effect on the isekai. Realistically speaking they could conquer everything in a few months so the author does this (I believe) to crate a more balanced situation, it's not how I would imagine things going if such a gate appeared in the real world but I'm not the writer here. On the other hand, the harem and childishness of the relations and the yet again virgin and clueless MC is annoying, MC is boring and hardly believable as are all who are around him, like the harem girls, they are all into him but not one seam to actually respect him and trash talk him all the time, even his army companions treat him like a retard even after he becomes an international hero, which is another part I don't like, some of the more childish "Hero" moments.

In any case, I find the story quite interesting and I think it makes sense other countries will want a piece of the pie and would even to go to war for it, with Japan to gain access and needless to say, with the other world's countries for their resources and land.
Current countries barely respect other countries sovereignty in front of benefit so in front of vast land and resources that are in the hands of countries with middle age's technology it's expected they would want to take advantage. Japan's approach to the whole thing is more doubtable but the author makes use of modern day's "pretense of peace and humanitarianism" to justify this, I think it's a good justification.
I do think the author takes some things too far, like the press side (I believe they are sensationalists that twist truth but I find it too one sided, why does the government do nothing to put their side in the news too?), or the idiot prince's plots.

Last, Piña colada? really? that's the name of the princess? make an effort with the names man, even Naruto is better and that's saying a lot.

Not recommended.
This series in its whole is just propaganda for the Japanese self defense force.
Once you realize that, the story loses all of its worth.

Utterly boring in so many ways. The author is clearly extremely biased against every other country than japan, the politics are garbage, unrealistic and boring, the characters are extremely uninteresting. I didn't like a single one of them, be it the mc or any other character. The motivations are logic is riddled with too many flaws to mention.

While the setting was interesting and it could've been good, this author has truly no talent for this stuff.

Interesting manga, it mostly focus on what happening around the characters then character development. Im glad the girls are not throwing themselves at the main male character. It focus on politics, war, military, culture, history, discovery. kind of like stargate travling to another place and meeting the new world.

Overall - While there are several battles, the series focuses on interactions. It deals with the cultural and military doctrinal clash between a medieval society and modern society. It also deals with the main protagonist's desire to avoid trouble clashing with his inherent decency and inability to ignore the people in trouble he encounters.

Main Protagonist - Most manga has the protagonist become the most powerful/skilled in his field or a bumbling fool. This protagonist is neither, instead having average combat and officer skills. His only exceptional skill is analyzing trouble and running away if needed. As part of avoiding trouble, he further masks his skills with an outspoken desire to avoid work. Yet when encountering people in trouble, he is unable to turn his back on them and helps as best he can.

NOT a harem - Of the 5 main females, only one truly shows any romantic interest in the protagonist who in turn has trouble returning it because of her age, appearance, and frightening power. Of the other 4, one is interested in his modern knowledge, one treats him as a replacement father figure, one is mostly scared of him as a perceived influential member of a hostile enemy, and one feels both guilty towards and indebted to him for helping save her people.

Romantic Interactions - Several of the side characters exhibit mostly amusing romantic interactions, usually between characters from different worlds. JSDF soldier worshipping a catgirl who is used to being looked down on by humans as a demihuman. A noble female knight falling for a commoner JSDF soldier. Foreign Ministry bureaucrat trying to cope with an underage noble girl who has publicly stated her intention to marry him once she is older.

Not a harem but close to it. The protagonist seems to attract different females around him. By chapter XX his team are all female. It's a sour point and really it shouldn't have gone into that path. One or two love interest is fine but not a possible harem. Whether they are interested in him or not is irrelevant, having a team of just women and him is off putting.

The world itself is fantastic. I love the different humanoids and there are tons of them.

It's violent, with slavery and rape and worse. Worth a shot, you might lke it.

As of chapter 48
It is fun to read but some times crucial details are not high lighted and the scans are of varying quality. Some times i feel lost, some times I have no idea some things which had happened before. All in all, i feel the more confused as the story goes on, like how

hardy is a woman?!! And when exactly rory made itami her servant?

I wish the manga could be more clear than this... still an enjoyable read. i would recommend it to others

Wow i feel so stupid now. This is Definitely one of those causes where i was missing out on something so amazing. I knew about this for a while but thought it would be a generic harem series and pushed it off but after finally giving it a chance i was amazed by how great this is. I just started it and caught up with the whole thing in the same day. This series is a MUST read for people who like darker fantasy's with a mix of military. It feels like an alternate version "Maoyuu Maou Yuusha" where it has a lot of real issues mixed with fanasty and war but of course with the military involved with this. It has a realistic interpretation of many elements and the story can get dark and Critical at many points which is really refreshing. The art is pretty good its not amazing but its still good and nothing to complain over. All in all this series a great Dark Military Fantasy series with some comedy as well.Its pretty great
PS. i have started to watch the anime and yea read this instead!! it is way better. They cut a lot of crucial moments and pretty much the entire R rating for generic bull.
