After the Devil's war on the surface world led to the Dark lord's imprisonment and peace between the realms. C'thelli yearns for a simple life of hunting monsters and raising their children as her own. It was honest work, and all was well. But when an ex - soldier of Satan's retinue turns up at her door for community service, all of her hard work is at risk of falling apart as she tries to balance raising four unruly children, while keeping Feimo's demonic tendencies from destroying the town.
