This is one of isekai I followed. I'm interested in how they put none power as main character and manage to make it interesting. I wonder how he can convince the mind control guy to be good. it's not going to be normal for sure.
Also, that arch bishop doesn't know how human's mind work.
On the another note, I recall there is this one girl who stay beside this guy when he killed demon lord, is that right? She might be the one who make this guy crazy and the person who our MC want to find.
Chapter aside, this scanlator doesn't have even translator, it still make this good and understandable. Prop to them for trying.
Even though, I would love to see more. But, I can't really support other than commenting.
