Wolfram von Bielefeld

Temperament and Pride: Wolfram is incredibly impulsive. He loses his temper easily, especially when his pride or his family's honor is hurt. He is a classic tsundere—hiding strong feelings behind a mask of aggression. Arrogance and Elitism (initially): As a purebred mazoku (demon), he initially despised humans, considering them inferior. Yuri had to work hard to dispel these prejudices. Pathological Jealousy: After becoming Yuri's official fiancé, Wolfram turned into an Othello. He is jealous of any woman, man, or even inanimate objects. His catchphrase is: "Are you cheating on me again?!" or "You weakling!" Loyalty and Duty: Despite his whims, Wolfram is a devoted knight. If Yuri is in real danger, Wolfram will not hesitate to shield him with his body or launch a suicidal attack. Character Evolution Before meeting Yuri: A selfish, spoiled youngest son who is used to getting everything he wants and despises half-breeds (like his brother, Conrad). After the engagement: His pride is wounded, but the Mazoku traditions are sacred to him. He begins following Yuri everywhere, initially to control the "weakling," but gradually becomes attached to him. Development: Wolfram learns compassion from Yuri. He begins to protect people, recognizes Conrad as a brother, and matures, though his explosive temperament remains.

Magic and abilities: He wields powerful fire magic and is an excellent swordsman. His weakness is seasickness, which makes him incapable of combat on ships.

Hair: Bright golden, soft, and slightly casually styled. The strands frame his face and reach the base of his neck at the back. A few unruly locks always fall across his forehead. Eyes: Large, expressive, and a rich emerald green (or spring green). In moments of anger or arrogance, they narrow, betraying his explosive temperament. Facial Features: Graceful, delicate, and aristocratic. He has pale, porcelain skin, a narrow chin, and a neat nose. Because of the youthful softness of his face, people often mistake him for a girl. Build Height and Proportions: Wolfram is 171 cm tall. He has a frail, slender build, making him appear younger than his brothers. Physical Fitness: Despite his outward refinement, he is not at all weak. Constant sword training has made his body toned, flexible, and resilient. Clothing Style and Wardrobe: Mazoku Military Uniform (Basic Attire): A bright blue dress uniform with high gold trim on the collar and cuffs. Gold epaulettes hang from the shoulders, and a white aiguillette hangs from the chest. The uniform is fastened with a belt with a buckle. Formal blue trousers and high leather boots complete the look. Despite his 82 years, by human standards, he appears to be a youth of 15-16. He has a classic "angelic" appearance: blond hair and emerald-green eyes. He wears a uniform similar to a military uniform.

The most famous and comical aspect of his biography is his accidental engagement to the protagonist, Yuri Shibuya (the new Maou). During an argument over dinner, Wolfram insulted Yuri's human mother. Yuri responded by slapping Wolfram. According to Mazoku law and tradition, a slap on the left cheek from a nobleman is considered a formal marriage proposal. Yuri was unaware of this, but Wolfram, insulted, nevertheless accepted the challenge and considered himself his legal fiancé. After this, he became insanely jealous of Yuri's every move, constantly calling him a "sissy" or a "weakling."

A purebred mazoku (demon), the youngest son of the former Mao, Cecilia von Spitzberg. He has two half-brothers, Gwendal von Wolter and Konrad Weller.
