User blog comment:Sixelfor/Special note about the story at the end of some chapters/@comment-26355219-20180227082538

Those were blog posts. SIU doesn't really write much these background stories anymore. But sometimes he still gives some more information. For example in this chapter blog post he wrote about "points" (currency): Vol.2 Ch.221: 39F - Hell Train: The 'Name Hunt' Station (24)

Here you have list of chapters, check them out if you want, but remember there isn't that much info: List_of_Chapters
