Lord Eat holds political leadership and serves as chief of elders within his futuristic society's elite class. This social stratum remains strictly segregated from lower ranks like pilots and laborers. His daughter Rena's forbidden romantic relationship with Godo, a man from an inferior class, draws Lord Eat into the central conflict stemming from their union.

To reinforce alliances between elite families and uphold the rigid social hierarchy, Lord Eat orchestrates Rena's marriage to Rock, a prominent political figure and prime ministerial candidate. This arranged union advances Lord Eat's role in maintaining societal structures.

When authorities discover Godo and Rena together, Lord Eat's elite status and enforcement of class boundaries contribute to Godo's severe punishment: loss of citizenship and imprisonment in an Icelandic labor camp.

Lord Eat aligns with Rock's political objectives, including energy extraction operations from Earth's mantle. These operations accelerate planetary instability, causing catastrophic earthquakes. Lord Eat's political influence supports these policies. During the resulting global cataclysm that destroys Earth, Lord Eat perishes offscreen alongside others.
