Grimoire of Zero

A beast‑born mercenary guards a cheeky witch on a quest for a world‑shattering spellbook.

In a war‑torn realm where humans and witches clash, a cursed breed known as the beastfallen walks the line between man and beast. Their animalistic forms grant them raw power, but also make them outcasts, hunted by both sides and forced into the life of mercenaries. One such wanderer, known only as Mercenary, roams the battlefield until a mischievous witch named Zero hires him as her bodyguard. Together with Albus, an eager young magician, they chase the legendary Grimoire of Zero—a spellbook rumored to reshape the world if it falls into the wrong hands. As the trio treks across scarred landscapes, Mercenary’s hardened exterior begins to crack. He discovers a fragile humanity beneath his feral skin, extending empathy to both humans and witches alike. Zero’s carefree antics and Albus’s scholarly curiosity push him toward a new purpose, turning a simple escort mission into a journey of redemption, friendship, and the uneasy hope of peace in a fractured world.

A lighthearted fantasy adventure following a witch and her beastfallen mercenary searching for a dangerous grimoire. Expect sword-and-sorcery action with moderate blood, mild fan service, and themes of discrimination that may prompt discussion with younger viewers.
