The Champion is the primary evil protagonist of the 2021 adult doujinshi "Youkoso Ryonamusume Channel: Zechou Jigoku & Chika Tougijou" (ようこそ りょな娘☆ちゃんねる~絶頂地獄&地下闘技編~) by author Sakamoto Kafka (阪本KAFKA).
The deuteragonist - a frail young woman - is drugged and unwillingly thrown into an underground boxing ring; presented as the "challenger". The incredibly beautiful and muscular champion shows up and shows her no mercy, even when the challenger cowers and voices that she wants the fight to stop. The muscular beauty at one point teased the deuteragonist that she might stop the match. However that turned out to be a lie as The Champion decides to be more brutal by breaking the challenger's arms when the latter moves to block, and also shattering her jaw with an uppercut. The Champion then violently ground and pounds the deuteragonist to a pulp until she dies. The story concludes with the crowd cheering on the sexy Champion while she celebrates her victory and mocks the corpse of the deuteragonist.
