Seriously man, why is this man so stupid? He read books and stuff about the hero and the demon lord. Both 8 year old girls already know who the fuck they are, and a 30+ year old can't do a 1+1 and realize who the kids are, the fucking hero cult appears looking for a hero and the retard still...
@Chizan quite a late answer, but in that case, the MC in that manga's world is viewed as the demon lord because the person who had that title before him was a tamer. The people in this world would have to recognize him as such in this case, and if it comes to happen it'd honestly be disappointing
Demon Lord for life, but next second he blushes like your average shoujo FMC while being more human than the most random farmer in the world... Did he lost his personality on the way while being succed into the abyss of reincarnation???? This doesn't deserve to be called Demon Lord in another...
