1. Physical Appearance As a user of fire, his design is characterized by a passionate red theme. • Hairstyle: He has spiky, bright red hair that looks like flickering flames. When his emotions run high, actual flames can erupt from his hair. • Clothing: He wears a stylish red long-sleeved coat-style top paired with purple pants. The design is very chic, carrying an air of princely elegance. • Accessories: His small round glasses are a charming point. He also has a red mark on his forehead and a small scar-like line under his left eye. • Expressions: He is usually seen with a confident smirk or a grumpy scowl, which highlights his elite, high-born atmosphere. 2. Personality In short, he is a **"proud, tsundere genius inventor."** • Confident and Arrogant: He has absolute confidence in his abilities and intelligence, often adopting a condescending attitude toward others. • Short-tempered and Passionate: He is very quick to anger, and his blood boils the moment a plan doesn't go his way. When his rage peaks, he literally "explodes." • Incredible Intelligence: Far from a simple brute-force villain, he is a genius engineer who creates advanced mechs and weaponry himself. • Devoted to Family: He is extremely loyal to his father, the Demon Bull King, and his mother, Princess Iron Fan, showing a touching side as he works tirelessly to restore his family's glory. • Surprisingly Comical: Despite acting like a perfectionist, he often overlooks small details or gets swept up in other people's paces, making him a lovable "butt of the joke" character. 3. Age • Actual Age: Over 500 years old. Since he existed before his father, the Demon Bull King, was sealed away 500 years ago, he has lived for at least five centuries. • Mental/Physical Age: As an immortal demon, he does not age; he is depicted with the appearance and mentality of a young man in his early 20s.
