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.

Memory magic is not forbidden magic, since is necessary to maintain the secret of the Conspiracy. Is the only magic that is used on living beings to be allowed, it's the exception that confirms the rule.
