Trace (Korean: 트레이스) is a South Korean webcomic series written and illustrated by manhwa artist Go Yeong-hun (고영훈) or known as his pen name, "Nasty Cat". Envy, jealousy, and selfishness, such dark sides of humanity can be seen in the work. The artist said that he wants to create the world of heroes with Korean identity.
It won the first prize and Netizen's Choice Award at the 1st SICAF International Digital Cartoon Competition held in 2006. Mr. Go was awarded with ten million won. The panel stated that they easily reached to choose it as the grand prix because not only it scored the highest point in the netizens' recommended works but also it fully meets the required criteria; characteristics of web manhwa technique, and artistic features.
Since April 2007 this manhwa had been featured on Daum, one of major internet portals of South Korea that is being considered a birthplace of many hit webtoons.
The story is set in contemporary South Korea. Some 30 years ago, unidentified creatures appeared out of nowhere and attacked people. They caused massive destruction wherever they went. The monsters are called "Troubles", and caused the world to fall into chaos. Along with the first appearance of the "Troubles", some number of humans were born with or acquired supernatural abilities. These mutants called "Traces" are the only ones who can fight off the Troubles. The Traces are also considered freaks and generally shunned by the community because some of them misused the powers for their own interest.
The plot revolves around two main characters. Sa Ghang-gwon, a high school student born as a "Trace" who attempts to hide his ability. The other is Kim Yun-seong, who acquired his "Trace" abilities during his early 30s. Soon after the acquisition, his wife and daughter were taken away from him for experimental purposes.
