This manga is such a shame. I think the premise is kind of interesting, an MC with limitless power that acts in a more pragmatic way, instead of the standard savior complex, but unfortunately, the writing is just really bad. It's hard to tell if Seika is a sociopath or just a straight up moron. There's a lot of attempted moralizing, but it's always against these strawman-esque caricatures of a position. Everyone is on the absolute extreme sides of an issue and I, the very smart MC, will sit in the middle because I am very smart and wise. If you told me this was written by a 14 year old, I wouldn't have trouble believe it.
There's this crazy narrative shift when it's revealed Seika is the
, he seems to immediately lose all sense of morality. When the adventurer city is about to be destroyed, his immediate reaction is to just leave the entire city to die. For some reason, he needs to be reminded of the several months he spent getting to know these people. Then once that is all resolved, he suddenly doesn't think they should leave the city because the princess sent him there to shelter him, so he was going to immediately leave at the first sign of danger because ?????
In the latest chapter, our god-like MC argues that slave owners probably invest a lot of money in buying slaves, so it wouldn't be right to free them, because he's just trying to provide for his family. "Won't anyone think of the poor slave trader's financial situation? He's not breaking any laws by owning people as property, so my hands are tied, sorry. If he loses his merchandise, what if that affects his family? Should his wife and kids go hungry because his slaves didn't like being slaves?"
The demons are a whole other issue. They spend quite a bit of time establishing that the demons are also living normal lives. Aside from being at war with humans, they have families and hobbies and dreams, etc. However it means absolutely nothing because Seika kills them immediately, and it's never brought up again. The next time he meets demons his first thought is just to kill them and then when he lets them go, he still second guesses whether he should have killed them instead. If no one in the story cares about the demons or even acknowledged that they are sentient thinking beings, then why should the reader?
