What happened to the cd?? was the cd like for every single killed ghoul entity? unless he gone a week worth back in time and the god vote and witch enslaving was already and still a thing.
Good point, the cd might have worked differently during time alteration. My theory is that after the time alteration, time rewinds back to before the demon king was born, which was before the village slaughter. It may also mean that the girl hasn't died yet and therefore, isn't counted as a ghoul. Just a theory tho, I know it doesn't perfectly explain everything. MC didn't mention a thing about it so I will see it as a plot hole.
But hey I will let it slide just to clown that d*ckhead.
