For anybody else who comes to the comments thinking "WTF is this, when does the story start??" It starts on page 50. Yes, page 50. Skip straight there if you don't want to click through 49 pages of blue and white art of the FMC for no reason.
It's because this is a comiket release that compiles all of Kiseki's weekly drawings up to that point (you can see the date they were originally posted at the top) and then adds a story as a bonus.
