Killing the People Reincarnated into the Other World: Cheat Slayer (異世界転生者殺し -チートスレイヤー-, Isekai Tenseisha-goroshi -Chīto Sureiyā-) is a Japanese isekai manga written by Kakegurui author Homura Kawamoto and illustrated by Aki Yamaguchi. The action is set in a parallel fantasy world, and revolves around a boy who confronts characters who have been abusing supernatural powers ("cheats"), which they gained after dying and being reincarnated as his world's new inhabitants. The series debuted on June 9, 2021, in Fujimi Shobo's shōnen magazine Monthly Dragon Age. However, the series was cancelled after just one chapter when readers highlighted the similarities between the villains in Cheat Slayer and heroes in similar works.
