Synopsis: I Reincarnated as the Little Sister of a Death Game Manga's Murder Mastermind and Failed

Makoto Kurobe's sole source of pleasure comes from hunting animals, with little interest in anything else, including his stepsister, Mai. But as time passes, Makoto finds himself yearning for a new prey to hunt. It comes as no surprise when he murders Mai and devises a deadly game that involves their entire class, with Makoto as the mastermind standing in the school's moonlit, crimson-splattered corridors, mirroring a scene from Mai's favorite manga. As a reincarnated Mai, she sets out to save her brother from his twisted plan. With knowledge of his dangerous, psychopathic tendencies, Mai uses every ounce of her being to help Makoto discover his passion for life, but his nature proves indomitable. Even as Mai works toward her goal, Makoto's sickening obsession with death leads him to a new target.
