They are the ones who kill the human's body and take their soul away to bring forth a new demon. They bring the souls to the Guardian once the Harvester is done with them.
They are mostly found in the Black Roses however some red roses may become Reapers.
Soul Harvester:
They are the ones who pick the human and spend time with them in order to create a ripe soul. They manipulate the him to create the perfect soul for their roses.
Normally the Red Roses are best here, but some Black Roses can charm the more innocent humans.
