Like the title says, I want a decent JP novel. By that I mean generic, meh, okay, not great but just good or not bad. Preferably isekai. No mature/R-18 or BL. Just need something to pass the time and relax.

Death March maybe. Well, most isekai are either decent or bad. Just search for the tag, changes are you will stumble upon what you are looking for.
