Thank you for making this disscussion thread. I would never learn about this manga if it weren't because of it.
As I see it, this chapter gives a compelling reason for a warrior that used to be so noble to go haywire over people isekai'ing to his world. I also enjoyed the fact that they made this chapter really long to explain the manga's premise, instead of only giving it a few chapters in after introducing essential concepts of the story, as some stories do. Plus, the chapter was overall funny.
I really hope that the author is able to keep it up and not make the story turn bland. Joking with the oversaturation of the manga industry with isekais is funny, but things are prone to turn stale if that ever becomes the only running theme of the manga.
