Don't think too deeply of this manga, it's a dumb family friendly story about a dumb&dense wimp MC who get told he got some real backbone after half a chapter dedicated to food, because...He can walk. Yeah. Little did they know, he can't speak without stuttering.
Editor prolly prohibits anything even remotely explicit, so even for the sake of congruity author won't show any bare skin even in the shower. Although I can see a public bath scene they'd half censor by focussing on MC going crazy because he can hear the water splashes.
Even stuff like slavery they mentioned in previous chapters, they kept it mild and surface level. Pretty sure author crossed the line and got slapped by editor there.
Honestly can't say they're wrong, when they say mangas are for children. When 99% of non-degenerate mangas are like that. No wonder since that's their target audience, but still.
