It has the comfortable writing style of one of my japanese anime light novels, and the setting is really interesting.
Some lines I noticed:
"She shoves a fork down the table before I can extend my arm." during the scene where girl orders the entire restaurant. Not wrong, but I don't know if you meant to write that.
"What's the heck that supposed to mean." Sometime after that.
"That is a foolish foolish decision." Around when human officer man is explaining his perfect plan. Also not necessarily wrong but I don't know if you intended it, could use a comma or _underline_ or slightly different second word to imply cadence.
"Anastasia plays with her teddy bear by flying it high in the air." Sounds like her bear is an RC plane.
I think it does a good job of introducing its cast with impact and initial presence so you understand their role in the story, but just at the start I found the jumping around was enough to confuse me for a moment. I just kept reading and it was ultimately fine, but maybe you could add something like the main character's hand visible for a moment when it switches to his immediate perspective; I think there was even an asset of him holding up a gun in the foreground you could use, just a bit more at the start to help the reader link his text to the character. Or not, it's not a significant thing, it's par for the medium.
The scenes with the main heroine succeed in creating an emotional connection, and the way the setting is presented creates intrigue and connects well with the character moments for how it leads a developing understanding of the circumstances these characters live in, but just toward the end I was starting to feel like the technical explanations and flashbacks were building up to a sense the story wasn't moving fast enough. I think that after the aforementioned investment, the reader wants to see the next step in what's happened to these characters, their relationship, and how the setting will affect them. Maybe you were just getting to that, but generally I feel the writing is stronger in the first half of what I read, if only because it fits well in the story's overall structure, but in doing so like all words they incur a tax that must be paid back quickly. I wouldn't want you to get bogged down though, in realizing a thousand forms of rewrites as that would threaten to ruin the writing style. It might be better to go onward first and decide which parts are strongest, then try to make the parts between fit neatly.
