I thought they were going to have such an obvious reaction, but damn, they are dumber than I expected.Oh no, the cult of lucifira is trying to revive the demon god lucifira!?!?
I mean Haruto is still OP, just that he more interested in laying low and supporting his imouto (who is on the way to OP).This is the isekai where it's not the hero is OP but the imouto. Our mc is just the vehicle.
I mean, yeah, the zombie incident is some pretty solid evidence that something foul is afoot. Demon god or not, that kind of thing doesn't just happen.
