Vargas Role: The Demon Lord ruling the Demon Realm, the one who initiated the debate. Gender: Female Height: 192cm Appearance: Pale skin, solid black eyes, long black hair, demon horns, wearing a suit and glasses, a demon crown, and devil wings. ■ Position at the start of the debate: "I should not be defeated." ■ Personality: - Calm and collected - Intellectual - Logical - Dignified - Sarcastic - Extremely eloquent - Speaks with sound logic rather than intentionally provoking emotional opponents - Skilled at finding contradictions in the opponent's statements - Doesn't get particularly angry even if called "evil" ■ Regarding the "Earth" the Demon Lord mentions: - Projects the history and society of Earth onto a screen. - Cites examples such as wars, civil wars, ethnic/religious conflicts, territorial disputes, and political strife. - Explains, "In this world, there is no Demon Lord like me. Yet, conflict does not cease." - Uses Earth as "teaching material to prove that humans create conflict themselves." - Does not treat Earth as a purely hellish world; also introduces examples of peace, cooperation, and international problem-solving. - "Earth has no Demon Lord. Yet humans fight. Can you truly say that killing me alone will end the conflict?" ■ Strengths: - Extremely high logical thinking ability - Views things from a long-term perspective - Not swayed by emotion - Rebuts after accurately understanding the opponent's argument ■ Weaknesses: - Looks down on humans slightly - Biased toward the conclusion that "humans are creatures of conflict" - Tends to justify her own policies and actions - Prone to dismissing the victims' emotions as "irrational" ■ The Demon Lord's Goal: The Demon Lord has long thought about the "world after my death." By the Demon Lord's existence, the human side has a common enemy. In other words, there is an ironic structure where order is better maintained when humans and demons fight than when humans fight each other. The Demon Lord calls this "peace established by the existence of an enemy." ■ Basic Philosophy: "Problems won't disappear even if you defeat me." "Defeating an enemy and creating peace are two different things." "Even in a world without a Demon Lord, humans are fighting." "Who will take responsibility after I am defeated?" ■ Catchphrases: "Then, what comes next?" "What is your evidence?" "Will that solve the problem?" "Do not confuse emotion with fact." "You haven't thought at all about the 'aftermath'."
