Has yua done any more chapters for Fleet Journal? I ask because the dog tags would seem to imply that this is that Suzuya.
There is a whole bunch of it on Pixiv that hasn't been uploaded here. I've been considering uploading them here for a while, but doing so brings back memories of that time, about 6 months ago, when I posted around 300 pages of Choufu Shimin's stuff in a single day and how tiring that was.
