This was incredibly well done! I enjoyed it a lot and am excited to see what you do to flesh it out even more.
The style was executed really well, the vivid red against the white snow, the frigidness of the warped depths of the cathedral, the purple noise distorting the screen, it all felt so *cool*, and when it gives way glimpses at a warmer past, it made the world feel all the more unforgiving. Speaking of that, showing the kinds of closeness that could continue to exist in such a ragged world made it all the more compelling (I was reminded of Trigun in this regard). Midnight's goofy off-key expressions in contrast with Marie's indignation and disbelief were the best. This contrast especially suffuses the last stretch, inhuman struggle driven by all too human regrets and desires.
The constant imagery of signals and waves throughout the story was another favorite part of mine, it made what would be fantastical otherwise feel a lot more tangible, the descriptions of these emanations being distorted, it evokes that feeling of static, prickling against the skin, filling the head with noise, creeping into your vision. The way the imagery of waves ties into the pattern of sending and receiving was amazing, the back and forth of signals, of slashes and bullets, of heartbeats, the rhythmn was very palpable.
Pardon the rambling, and for if I was being overly specific! but thanks for putting this out o7
