American Witcher

As a retired Navy SEAL, Han Yu only wanted to make money by boxing in the United States after retirement, but he became a mercenary at the invitation. As expected, something unexpected happened during his first mission. He discovered that the world was facing the threat of demons, so while working as a mercenary, he could only reluctantly work part-time as a demon hunter.
