As the studio erupts in chaos over Ho Go's new comic, one of his former students - Ga-In - shows up at the door! Da-Il, who ends up sharing his room with his boss' former protégé, wakes up in the middle of the night to find his guest in the grip of a huge monster! Under attack himself, Da-Il is thrown into a tragic story from Ga-In's past, where he will have to learn that Mu-Huk can't always save him and even the powers of a Croquer have their limits.

Da-Il has a new job working for a famous comic creator. It would be a great opportunity...if Da-Il had any artistic ability. Da-Il fears he'll never be able to create art, until he meets Mu-Huk, a ghost who takes form based on Da-Il's creativity. The budding artist soon learns he has the skills of a 'Croquer,' someone who has the ability to shape the stories vengeful ghosts by entering the 'Dead Zone.' It's a lot for a young man to absorb, especially when Da-Il learns he'll be the main character in his boss's new book - Croquis Pop!
