Same, I do not really mind the introduction of guns but mostly the half assed way of copy-pasteing a sophisticated gun in a fantasy setting out of the blue. Best option would have been a way to replicate the effect of a gun with magic stones and such.

I think you are missing a couple of points:
-He's already identifying himself as the teenager boy, instead of the previous life he lived, making the awkwardness resulting from the age difference a lot less important.
-you're using moral costumes from modern times. You don't need to...
Am I missing something? I thought gunpowder and firearms were already present in this world... Chapter 1 has a cannons to represent the military power of the Prince's sister.
I think it's because mangadex has the translators themselves upload the chapters, and right now the English one has a programmed delay of about 14 days. It's uploaded but blocked. You can read it at mangastream's site.
