I remember he’s been stabbed and shot in the past and we’ve seen him shirtless in the manga a few times so why doesn’t he have a scar and why does no one ask about them if he does have them but can’t be seen cause of the art style?
Plot armor insurance will sometimes cover the costs of any plastic surgery/scar removal as necessary so you the MC can keep looking and being the star you’ve always been. get yours today!
You should be more concerned about the fact that death follows him everywhere and not why he doesn't have any scars.
Is that really your concern? If I were you I'd be more worried about the fact that multiple winters, summers, falls and springs have passed and conan nor anyone else around them hasn't aged a single year! Conan alone probably solved more murders in Japan in a year than there are total murders in the entire country. And lets not get started on how Kogoro is still alive after being hit so much with anesthetics. So you know, anesthetics is something you gotta be really careful with and requires a profession in the field. Otherwise you can easily kill someone. Not to mention all the explosions he has ridden on his skateboard. But yeah... scars... lol
