Hey look, a decent (i)sekai (remember isekai means "other world", not "transported to another world", that's just the generalized theme term) OP MC manga, who would've thought they existed.
Now, my definition of "decent" may pretty well differ from anyone else's but i think it's pretty nice and chill, and so far the only plot point that's kind of driving the story is the fact that the final boss wasn't actually the final boss. So yeah, if you want a nice, not overly good nor bad read, might as well read this one.
