The Hast government is shown be very bad, with very abhorrent treatments on its women soldiers whom they rely on for the war. At one point they used them as nuke carriers, but later on some of these women soldiers began to show great potential so they managed to strike some sort of deal with the military, in which the
Transfer units work toward the war efforts, in return they don't get outright experimented on and retain free will, etc.. Later on, we learn that they keep experiment on these units when they could, which provides a very important point of struggle in the story. On the other hand, we have the Seconds, which are the invaders using massive amount of AI drones to conquer the planet while they themselves supposedly stay in cryogenic sleep on spaceships,and they are shown to be even worse assholes. Massive amounts of people conquered by them are put into concentration camps, and it's implied, through discussion relating to the Pan-Human Alliance (UN-like organization in space but controlled by the Seconds), that should the Seconds win, then the outcome would either be slavery or genocide. The main characters are therefore in very precarious situations.

The unique setting allows the author to discuss topics relating to motherhood, morality, etc. which makes for an interesting read. The characters in the Transfer units are quite diverse, with a range of different backgrounds for each. Later on, more political intrigue is thrown in, leading to good finale. However, there are some criticism which I would like to make. Firstly, the entire premise is based on the facts that only the Hast country, and not the Seconds, could utilize the Transfer technology (by putting Niebass organs into their women soldiers's wombs). The question is why ? It does not seem realistic for a downtrodden, near-defeated country to suddenly have such a big advantage like that. And why has the Seconds not managed to research such a technology, considering that they are so technologically advanced. In fact, in one chapter, the Hast ambassador, during his discussions with the Seconds's diplomatic AI, also asked himself the same thing! For a sci-fi story, this story strangely enough rests entirely on a mythical premise. Later on the story continues to rely on this, with one Hast scientist (later shown to be a traitor who worked for the Seconds) openly stating that it's better that the Transfer technology is not completely understood, since if it is, then the Seconds would eventually manage to use it themselves, since they are technologically superior. So the story worships the mythical element which allows for women soldiers of Hast alone to use the Transfer ability. The author could have written this part a little bit more realistically, by saying that for example, the Hast government, after becoming aware of this technology, actively sought out the Niebass (which are shown to be very sentient) for some kind of alliance against the Seconds, which would make the story more believable, while still allowing the author to discuss the topics which they wanted to discuss.

Secondly, the Seconds are shown to be one-dimensional villains and completely evil (pun not intended). We are shown only to one of its "diplomatic AI" on a neutral station, which do nothing but speak disparagely of the Hast government and its people. Two other characters on their side are shown, however they are traitor scientists in the Hast government, which were hired by the AI, and do not clearly show the inside of the Seconds's society and government. The plot says that the Seconds conveniently put themselves to cryogenic sleep while the AI sends its armies to conquer the planet Hekiou, which is not a sign of good writing. You see, even in Nazi Germany there were a whole bunch of people opposed to them, and those people did fight from the beginning to the end, and they got arrested or worse. But here, the story says that all of the Seconds's people go to sleep! The author could have provided us some Seconds's characters who are opposed to the war or something, that would have been much better.

Thirdly, the women in the Transfer units are shown to be very strong-willed and independent people. However, the toughest of the bunch, namely Sergeant Armea and Sarah (forgot her rank), still meekly followed the Hast government while they treated them badly. It is said that after a period of horrible treatment in which women soldiers are used as guinea pigs for carrying nukes, they managed to win back some rights for themselves. However, the point is for all their toughness, they did not press adequately enough. For example, they did not try to put people sympathetic to them in the Hast government. Even the Seconds managed to put a whole group of traitors in the Hast government, yet they had no one in there who could help them LOL (except for two scientists). I mean, come one, we are talking about soldiers with teleportation abilities here. Why did they not try to teleport to the houses of those military and scientist douchebag and, I don't know, beat the sh*t out of them or something ? (I know that they rely on the "access points" to move around, but still they could contact their Niebass friends and strike a deal or something to help them build more advantageous access points you know). Or maybe if they wanted to do it more shrewdly, they could just take advantage of the fact that since the Transfer soldiers are literally the reason that Hast has not been conquered yet, they could do some politics and start some sort of religion around the Transfer soldiers or something, which would massively improve their standing in Hast's society. I don't know, just make shit up, do anything to make your situation better. They also did not actively tell the new recruits about the real situation, which is very bad. In those kinds of situations, you always make sure as many people know about your plights as possible. The point here is that they (Armea and Sarah) gave up politics, which considering they were treated so badly is just wrong. And in the last chapter, after the Transfer unit managed to help Hast win the war and defeated the Seconds, some government official came and asked the MC to join them and help nuke the other countries as well so that Hast could take over all of Hekiou. Then the MC literally ran away (via teleporting to the Niebass, probably)! This is a very fatalistic way of handling problems, especially for ones with teleportation abilities to boot. Since they are treated so badly, the women of the Transfer units should have tried to fight more instead of giving in like that. They could always try to teleport to those military and government assholes and blow them up to make a point or something, although they could also try to go around as peace ambasssadors or something of that nature, I don't know in those kinds of situations you have to try all options. The point is not to just give up and run away.

Fourthly, most characters are female, and male characters are sparse. We get Mana Oga's boyfriend, who in the first chapters, are shown to dislike her joining the Transfer unit and get alien organs put into her body. But later on, we saw him working on the fields with Mana's younger brother i suppose (i am fuzzy on this part) and they barely avoided a Seconds's drone ship from shooting them. Later on, the Seconds conquered the area and put them in concentration camps. I think that the author initially wanted to put this character some place important but later on ditched the idea, which I think is not very good. The point here is that for these kinds of stories, the author should have strived for further balance to make the story better.
