do you have any recommendations related to that? I'm starting to get fond of those types of mcs..
My rec is "Im Really Not the Demon Lords Lackey". Its got a shit ton of weird fan service but if you can ignore that the plot is goated
this one is the closest so far imo:

Illusion hunter from another world is so similar to this too
I love cosmic horror mcs who think they're just normal humans when the side characters around them view them as something they can't normally comprehend
