Fuutarou Gamagoori

Fuutarou Gamagoori is one of the most brutally cruel, culturally impactful anti-heroes in manga history. Born into dehumanizing poverty, his worldview shattered when he watched his mother dying because they lacked money for medicine, descending into trauma. Operating as a cold-blooded sociopath, Fuutarou discards his humanity to climb the social ladder. He systematically orchestrates horrific crimes - including the ruthless murder of childhood friends, innocent brides, and business partners. His extreme avarice popularized the term "Zeni Geba" (money-grubbing demon) into the Japanese lexicon. Fuutarou remains a chilling, nihilistic icon of capitalist corruption, recognized as the ultimate personification of a human monster bred by a ruthless society.
