My Demon Roommate: The Single Mom's Guardian

Penniless single mom Sarah rents a century-haunted house with her five-year-old daughter, accidentally awakening the dormant, irritable demon Elias. Believing they're doomed, the quick-witted little cutie instead shows zero fear and simply enlists the demon as her "trash-taking roommate"! The cold, cruel Abyss Lord has since fallen, transforming into the ultimate wife-and-child-protecting maniac. When her abusive ex-husband — coveting the fifty-million trust fund — colludes with a fanatical exorcist to take her daughter away, Elias completely snaps. Even if it means shredding the contract and burning his century-old magic to become a mortal, he will deliver a dimensional strike and tear the scumbag apart! A century-spanning abyssal redemption, a single mom's desperate counterattack, the scumbag punished and thrown in prison. Cutie-assist plus maximum contrast adorableness — dark guardian and explosive revenge, both firing on all cylinders!
