Kekai Kotaki

Turning an ancient, gloomy castle into a peaceful sanctuary for hurt and lonely demons sounded like a great idea, but the utopia part is taking way too long to kick in. Nina is doing her best to manage the new residents, but with her sister gone and her mother acting incredibly distant, the pressure of being the very last Slayer is weighing heavily on her shoulders. Her newly restored powers feel strangely off balance, tainted by the evil succubus who previously stole them. While Nina struggles to control the lingering darkness inside her own mind, a terrifying new threat emerges in the outside world. A bizarre, recurring triangle symbol is appearing everywhere, linking a deadly demon drug ring to someone uncomfortably close to home. Apparently, surviving one apocalypse was not quite enough. Return to a fierce, witty, and deeply emotional expansion of a legendary monster-hunting universe, where the forces of darkness never stop knocking, and a hero's toughest battle is often against herself.
