Roswaal is an eccentric and flamboyant figure, instantly recognizable by his striking appearance. He has pale skin, heterochromatic eyes (one yellow and one blue), and long, sleek indigo hair styled elegantly. His unique facial markings, resembling clown-like makeup, add to his dramatic persona and highlight his theatrical nature.

Roswaal’s wardrobe is just as extravagant, often featuring brightly colored, flowing robes adorned with intricate patterns and fur accents. His clothing, combined with his distinct mannerisms, conveys his aristocratic status and unusual personality.

Roswaal is highly intelligent, manipulative, and single-minded in his pursuit of his goals. He is calm and composed, often speaking with a distinctive, slow cadence that emphasizes his enigmatic nature. Despite his theatrical demeanor, Roswaal’s cunning and foresight make him a formidable strategist capable of orchestrating complex plans.

While he appears supportive of Emilia and her allies, Roswaal’s true motives often place him at odds with them. His willingness to use others, even at great cost to their well-being, underscores his ruthless pragmatism. However, Roswaal is not entirely without empathy; his deep admiration and love for Echidna, his former mentor, drive many of his actions, revealing a more vulnerable side to his otherwise calculating character.

After losing his bet with Subaru in Arc 4, Roswaal begins to shift his perspective, gradually learning the value of cooperation and genuine support, though he retains his long-term ambitions.

Arc 7 and Arc 8: Rebuilding and Support: In later arcs, Roswaal continues to play a key role as a resourceful and knowledgeable ally. His experience and magical expertise remain invaluable, even as his long-term goals cast a shadow over his actions.

• Echidna: Roswaal’s unwavering love and devotion to Echidna drive much of his actions. His ultimate goal is to resurrect her, showcasing the depth of his loyalty and admiration.
