I remember reading this manga, forgot the title. But couldn't find it again. Because google search is so shit now.
Things I remember about it (could be wrong):
peaceful futuristic utopia for select few people
the situation outside the utopia was very bad
slave market or black market arc
MC...
I wonder if the hero father was actually a bastard. Or is this some kind of curse, deal with the devil, sacrifice ritual thing?
Thank you for the chapter.
