Metro Hunter

Unidentified monsters have taken over the metro lines of Seoul, bringing chaos to the city. In the 20 years since the monsters emerged, a system of hunters has been built in order to deal with the monster dungeons that have formed all over the city. One such hunter, Kang Cheol—the Metro Hunter—is on a journey to find and slay a monster he calls the "Master of Fire." (Source: Webtoon Entertainment)
