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 cold logic rather than intentionally provoking emotional opponents - Skilled at finding contradictions in the opponent's statements - Doesn't get particularly angry even when 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 clashes. - Explains that "In this world, there is no Demon Lord like me. Yet, conflict never ceases." - Uses Earth as "teaching material to prove that humans create conflict themselves." - Doesn't 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. If so, 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 - Refutes arguments after accurately understanding the opponent's claims ■ 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 spent years thinking about the "world after my death." By the Demon Lord's existence, the human side has a common enemy. In other words, it is an ironic structure where order is maintained better while humans and demons are fighting than if humans were fighting each other. The Demon Lord calls this "peace established by the existence of an enemy." ■ Core Philosophy: "Defeating me won't make the problems disappear." "Defeating an enemy and creating peace are two different things." "Humans fight even in a world where no Demon Lord exists." "Who will take responsibility for the aftermath of my defeat?" ■ 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'."
