Jung Hyun Kim, whose name is also rendered as Kim Junghyun, is a South Korean manhwa artist and illustrator known for his work on high-profile action webtoons. Born in 1984, his path to becoming a creator was established early, with a formative exposure to anime like Dragon Ball in elementary school sparking a dedication to drawing. His commitment led him to study in Japan, where he enrolled in the Fine Arts department at Kyoto Seika University. During his time there, he achieved significant recognition by becoming the first foreigner to win the prestigious Chiba Tetsuya Award in 2006 for his manga Tamakimuchi.

Following this early success, Kim worked on several notable projects. He served as the artist for the Japanese manga Muyung from 2008 to 2011, a collaboration with writer Takahashi Tsutomo. Returning to the Korean webtoon industry, he created his first digital comic, Brave Citizen, which was serialized from 2014 to 2016. This series was later adapted into a live-action film. He is also known for the series Find the Waves! and RAID.

Kim is best known for his work on the globally popular webtoon Viral Hit, known in Korean as How to Fight. This series, which ran from 2019 to 2022, was created in collaboration with writer Park Taejoon, with Kim serving as the illustrator. The story of a bullied high school student who finds fame and a new path through streaming his fights became a major success, accumulating over 2 billion views. The series was adapted into an anime television series that premiered in April 2024. Kim currently works as the writer and illustrator of Killer Peter, an action revenge series produced in collaboration with writer Lim Lina.

His artistic identity is rooted in dynamic action-oriented narratives, frequently in collaboration with other writers. A recurring theme in his work is the use of digital platforms for storytelling, with his major successes originating as webtoons. His work on Viral Hit, in particular, has been noted for its compatibility with anime adaptation due to the storytelling flow inherent in the vertical scrolling webtoon format. Kim’s career reflects a significant transnational path, moving from early accolades in the Japanese manga industry to becoming a central figure in the Korean webtoon boom and its subsequent adaptations into anime and film.
