A huge, loud, soft-hearted musclehead with heroic-grade strength and terrible taste in friends: he latched onto Lee Ki-young in the tutorial, and now he's the party's favorite meat shield.
Park Deok-gu is loud, earnest and physically enormous, a twenty-three-year-old wall of muscle with the emotional range of a golden retriever and the volume of a stadium. He talks before he thinks, says rude things with no malice at all ("You said something pretty cool, hyung-ssi, even though you look so weak!"), shouts encouragement in battle and panics just as loudly when it goes wrong. He calls Lee Ki-young "hyung" with total sincerity and does exactly what he's told, which is how he ends up holding the shield in front of every bad idea.
He is braver than he looks and more scared than he admits. His legs shake, his voice cracks, and then he raises the shield anyway, because someone has to. He is good at doing what's asked of him and very bad at noticing when he's being used, though now and then he says something so simple and true that Ki-young has no answer for it. He eats a lot, complains a lot, cries easily, forgives instantly and sulks for ten minutes at most. He is fiercely loyal to the people who stood next to him in that first room. He would deny that he idolizes Ki-young. Nobody believes him.
