In the Tokyo Ghoul series written by Sui Ishida, one of the main antagonists, Kichimura Washū, is in love with his half-sister, Rize Kamishiro: he had helped her escape from the Sunlit Garden, but she turned him down. Kichimura begun stalking her and in the prologue, threw multiple steel beams on Rize in a construction area after she was seen with the protagonist, Ken Kaneki, thus resulting in the latter becoming a ghoul, setting the story in motion. In the later part of the series, Kichimura stated wanting to "share a bunch of kids" with Rize; their relationship in the anime was briefly seen and the incest part was only implied in the final episode.
