寄生獣 [Kiseijuu]

Hitoshi Iwaaki's Parasite (1990–1995, Kōdansha) is a landmark sci-fi horror manga that redefined the body-horror genre. Over its ten-issue run, the series follows high school student Shinichi Izumi, whose right hand is taken over by a sentient alien parasite named Migi, forcing them into an uneasy symbiosis. As other parasites begin murdering and replacing humans, Shinichi and Migi must navigate a world of grotesque transformations and philosophical questions about identity and humanity. Celebrated for its tense storytelling and emotional depth, this series remains a touchstone for mature, thought-provoking manga.
