Chrollo wasn't a fond of this system, the demons were persecuted and tracked. However, he couldn't do much but pity them. Until he got sent into one of the research labs who were trying to breed humans with demons. Chrollo took a deep breath and entered the room they told him to go to, only to find a female demon tied up to a bed. The demon stared at his military uniform and seemed completely desperate. Chrollo knew he had one job : make her pregnant.
