Gong-Ja Kim is an aspiring hunter who is jealous of the #1 ranker: the Flame Emperor. Before entering the tower, Gong-Ja lived his life as an orphan. Even after entering, he was a below-average hunter who adored and worshipped higher rankers. This admiration later turned into envy though, and Soo-Ha Yoo became the main subject of Gong-Ja's jealousy. This below-average hunter's life changed when he received an S-Rank Skill Card for the toxic envy he developed. His gifted S-Rank Skill Card allowed him to receive the power of those who killed him.
