I very much understand yhe desire to kinda "fly low" or to otherwise stay out of public perception.
I get it.
Totally get it.
but.
But, but, but....
Once you cross the line into being crazy tough, you don't get to say "oh, noes! I mustn't stand out! Because Japanese tropes!"
What kind of childish idiocy could possibly lead to this train of thought? I mean, nobody in this kind of situation actually wants to be famous; not unless they've really been severely abused and are seeking revenge or something... but then our MC would absolutely want people to know!
It's just stupid, and I don't understand this useless train of thought in a story like this; it's not a given that people in a medieval magic society would fight hard to act like a modern Japanese salaryman; it completely destroys any suspension of disbelief, and is the worst form of lazy writing.
(Obviously, imma keep reading this trash, but I just gotta get this out of my head before I throw my phone...)
