Grimoire of Zero

Grimoire of Zero is set in a world where humans and witches are at war. However, there's another group - the beastfallen - who possess the physical strength and characteristics of animals due to a curse. As a result, many beastfallen are forced to live on the fringes, taking on work as sellswords by targeting witches. Zero, a lighthearted witch, hires a beastfallen mercenary to protect her and Albus, a young magician, as they search for the Grimoire of Zero.
