So yeah, I decided to ignore chapter 16 for the time being. I might translate it someday, but for the time being "chapters from dev perspective" are punished with sealing. Their crime is - spoiling, being stupid and inconsistent with the novel style and setting, also being dumped from LN by the author.
And so, here is the chapter 17 link. Light Novel-wise chapter 17 is the one that ends the volume. So from chapter 18 we are entering Volume 2 content of the LN.
Make sure to support the author, the illustrator and publisher. Buy the books if you can, visit the author's page or the work's page on Narou if you can't. You can find everything on the series' main page.
