Okay, the spacing is an issue. This is basically two notches above a fat wall of text (The line breaks and single spaces) but spacing is a must, and the story is hard to read.
This is NOT a good one-shot. This is simply due to the fact that this conclusion does not resemble a one-shot conclusion (It is in NO WAY conclusive.) You may either 1) Want to add a final conclusion or 2) Multi-chapter story.

Your OC's need explaining and an intro (You just brought in people with no explanation - how do we see them in our head?)

Also, it is much better NOT to rename CR-S01 (Most people recognize him as such, and therefore it is better to either use CR-S01, a shortened version of that, or his 'real name', Erhart? Something like that)

Also, re-read, there are numerous grammar/spelling errors and mistakes.

The humor is interesting.
All in all, spacing and OC's are the main issue.
