Grimoire of Zero

ゼロから始める魔法の書

by Kakeru Kobashiri, Takashi Iwasaki

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. The two begin their travels with this agreement binding them together, with the mercenary serving as Zero's protector, though he despises her kind. (Source: Wikipedia)
