The thing I want to make clear immediately is that overall, this story both shows that you are continuing to improve, steadily if slowly. The entirety of your entry, both parts of it, were lightly sprinkled with typos, awkward grammar, and inappropriate usage of verbs. However, this is perhaps the first time I have read through one of your stories without actually becoming overtly bothered by their frequency. If I had to pick one, I would say your usage of appropriate verbs still needs the most work, 'blasting beams of power' by way of example. Keep at it.
As far as your actual arrangement goes, there is a certain lack of descriptive/visual imagery. I barely have any idea what any of the characters look like or how old they are. You do a decent job of capturing the states of mind as well as their tone of voice and expression, but otherwise I may as well have been reading about stick figures. This also extends to scenery, incidentally. Aside from the brief description of Earth and the rings of Saturn, there is very little depth in your manner of presentation. A good example of this would be the armor our Plutonian heroes wear, which is never described as anything except, vaguely and unhelpfully, as 'armor' with a random color permutation. I have no idea if these are skin-tight suits, streamlined power armor, bulky environment suits, etcetera. Just a little bit of elaboration right at the beginning of the story would have massively improved the visual aspects of the whole thing. A similar problem is observable in the helmets everyone wears that grants them complete, total awareness of the entire battlefield - without telling us how. You do not need to provide a technical explanation, but providing one at all, however flimsy, would have been nice. Is it a telepathic effect? is it wired directly into their cortex? What is going on? No idea. In the future, you might want to elaborate more on such details. Not necessarily anything elaborate or fancy; a single sentence can sometimes have tremendous, far-reaching influence on the entire story (Be thankful you did not inadvisably provoke detailed inspection of the scientific aspects of your story like
@mdk did).
I liked the arrangement of dialogue in the story, at least for the most part (refer to the first paragraph). The flow of conversations is remarkably smoother than in the past, and well put together. It still is not perfect, but represents a marked improvement over previous submissions.
I also liked your characterization of Eviri. You did a good job of conveying her conflicted state of mind; her wanting to protect Pluto while struggling over whether or not she was really doing the right thing. Her actions during the mutiny and later, during the fight over Earth, are a neatly structured staircase of character growth and progression. Although I did not actually like the character herself, I did appreciate the depth she acquired over the course of the story-arc. Well-handled.
Perhaps the single biggest problem I have with this story is that, given the effort and length, the actual plot and its logical rigor are both rather weak. Juvenile, in fact - the whole time I felt like I was reading a children's adventure novel. Given your statement that the story is basically of the magical girl genre, perhaps that sort of arrangement is inevitable, or else I simply do not enjoy the sort of over-embellished logic inherent in such stories. From my perspective the whole of the story is beneath your skill, or at least it should be. I was never engaged and, to be honest, I felt like my time was being wasted while reading through it. The story clears the basic standard of quality expected of good storytelling, but in part only because I decided to lay aside any misgivings I had concerning the sophistication of the plot since there was a significant chance my opinion would then be swayed by a preexisting bias against the genre.
This is a bad way to have cleared the challenge. Under normal conditions a story should be of sufficient quality to win past the misgivings of a judge who is not making an effort to be objective. I am seriously considering revising the rules of judgment and have each submission reviewed multiple times in order to circumvent this problem in the future, so let it be known:
Going forward I will expect better from you.Also, I get that Aimer was a bit dumb, but descentry is a made-up word. I made it up. It is not actually a valid word. I was trying to sound cool. Please do not take my usage of a nonvalid word as an excuse to use it unless you also happen to want to make up words to sound cool.
