I seriously don't like how it's 99% of the time following those 2 humans. The whole audience is here for MC's world domination shenanigans, and this manga has devolved into a romance between 2 side characters. Seriously, it's boring as fuck now, and the slow progression doesn't help either.
Seriously, why do so many manga become like this? Fantastic start and setting, but it's ruined by cliche tropes no one, except maybe only the Japanese audience wishes for.
