Courage Guild

The Courage Guild is a minor South Korean guild in Solo Leveling, small to medium in size and without the roster to compete with the major guilds for the best gates. Its most notable outing is a raid on a B-Rank gate that opens at a high school, a site where a gate had opened once before; the Korean Hunters Association cordons the area off, and the guild's strike team, holding the permit, goes in. The team works through the magic beasts inside without much trouble. What stops it is a closed set of doors that the hunters take for the entrance to the boss room and cannot open by any means available to them. Unwilling to leave with nothing to show for the permit they paid for, they stay at the doors.
