Mercenary is the main male protagonist of the series; who accompanies Zero and Albus to find the book known as the Grimoire of Zero, which can destroy the world. His real name is unknown, as is his human form. As a child, he was consistently mocked for his animal-like appearance. He was beloved dearly by his mother and father, who were fully human, but had lost them due to raids of cruel humans.

In the spinoff, he is a minor recurring character alongside his witch mistress, with a rounder face. Despite his size, and weight, he is not as strong physical as the two decade-old, childlike beastfallen Lilly.


Mercenary has white fur with light grey stripes and a scar on his nose. His build very stocky. He quite clearly resembles the look of a white tiger.


He's very gruff and stoic. He is usually very blunt, and can be quite short tempered.


When Mercenary was young, he was born as a beast-fallen and was cast away from his village. He was later adopted by human parents who accepted his beast-fallen form.

Years later, they were attacked by bandits and hid Mercenary in a farm while his family fight against them. Later, he finds that his new family was killed, thus killing the bandits who killed his family.

Five years later, he has achieved his dream of owning a tavern for humans, sorcerers, witches and fellow beastfallen alike. He is much calmer and has retained his hardhearted nature, but now cares of not killing those who are innocent.
