Zero kara hadžimeru mahó no šo

Like most Beastfallen, the half-tiger known as Mercenary hates the witches who created them, so when he's offered a chance to hunt witches, he quickly agrees. But things go spectacularly wrong when he's rescued by a witch instead and she wants him to become her bodyguard! Making matters worse, she's seeking a missing book, the Grimoire of Zero, which contains the secrets of Magic, which could possibly end the world if it falls into the wrong hands. (Sentai Filmworks)
