Juzo Haida amassed wealth as a politician during Japan’s asset price bubble, later resigning for health reasons. His irascible temperament manifests in lashing out against opposing viewpoints, reflecting narrow-minded ideals. He displays condescension and indifference toward his family, alongside classist disdain—labeling society’s lower classes "bottom-feeders."

Juzo treats his wife as property, dismissing her well-being, including reminders of his doctor’s alcohol restrictions. His relationship with older son Haida fractures under unrealistic expectations; he deems Haida a failure and disgrace after antisocial songs from Haida’s high school band surfaced online. When meeting Haida and his then-girlfriend Retsuko, Juzo’s disrespect drives Haida to abandon seeking paternal approval.

Younger son Jiro, groomed as Juzo’s political successor and favored without genuine compassion, rebels upon discovering Juzo caused Haida’s car accident. Jiro brands Juzo a "fossil" and proposes legislation mandating politician retirement at age 65—a direct challenge to Juzo’s position. Jiro secures a landslide election victory, enacting the bill.

Juzo dismisses Retsuko as a "chippie" or gold digger exploiting Haida. His political influence and toxic family dynamics cement his status as a powerful yet resented figure, spurring both sons to defy him. His documented arc concludes with electoral defeat by Jiro and alienation from his family.
