Yongsa High: Dungeon Raiders

An Earth in the 21st century that has fused with another world. An era of "dungeons" teeming with monsters and the "adventurers" that raid them. Also, the most elite educational facility in South Korea that fosters these adventurers: "Warrior High School." Although he was once considered one of the greatest adventurers in Asia, he has been accused of false charges and, while dungeon smuggling in order to pay for his sick father's medical treatments, Jaryong Yoo comes across one teen. "You there, get in Warrior High School." This is a story about a young man who's lost his dream, hiding his identity, finding himself once again. (Source: Kakao Entertainment Corp., translated)
