Grimoire of Zero / ゼロから始める魔法の書

It is the year 526 of the Liturgical calendar. Witches and their sorcery are notorious throughout the land, though knowledge of the existence of magic remains elusive.

A half-man, half-beast mercenary, his kind scorned by the populace, dreams day and night of becoming a human.

However, his fateful encounter one day with a witch by the name of Zero turns his dreams into reality.

She offers to turn him human if he will escort her as her guard on her search for a magical tome, one that possessed powerful knowledge which could wreak havoc in the wrong hands.

With the mercenary serving as Zero's protector, the two begin their travels.
