I did enjoy this show. It's not great. It could have been way better if it had started actually explaining some things instead of just adding new themes and power systems.
Marc arc was the most boring by far. If this gets a second season I will definitely watch it, but I won't be unhappy if it doesn't.
It was even hell to read... I stopped after Vol. 6 when I should have stopped way earlier.. once 80% of the books was just making clothes for his harem
