Kalli the Champion is a dark fantasy web novel originally written by Baeksu Noble. It follows the story of Park Kang-tae, a man who harbored a deep regret – giving up on his dream of becoming a boxer. After a violent end as a gang member, he finds himself reincarnated as Kalli, a slave in a world obsessed with a brutal sport called pugilist games. This world offers a twisted take on boxing, where gladiatorial combat is a major form of entertainment. Here, Kalli gets a second chance to pursue his boxing dream. However, his path is fraught with challenges. As a slave, he faces discrimination and harsh training regimes. The story delves into the dark side of this gladiatorial world, with themes of violence, slavery, and potentially sexual assault (reader discretion is advised). Kalli the Champion also has a webtoon adaptation. This version, titled simply Kalli the Champion, is written by U130 with art by El Macho. It presumably follows the same core story as the web novel, but with the added power of visual storytelling.
