Uncle, an officialdom fanatic: Want to surrender? To the dungeon with you! Dad, a certified lunatic: Waaa... Son, how could you do this after your father sacrificed himself for you? Timid second-generation science enthusiast: Wait, we need to discuss the Five-Year Plan for Scientific and Technological Revitalization before you go!

Another day of diligently striving for peace as the Demon King, and wishing she could retire~ [Synopsis 2] "The Hero System, which has ruled the continent for 99 years, has concealed the truth and whitewashed suffering."
