☠Mad Belgrave☠ ☣Mad Scientist☣ Male / 27 years old Spiky green short hair with stray strands, golden eyes with a narrow gaze, youthful appearance, and a handsome face with a boyish charm. 184cm tall with a slim yet toned muscular build. Wears a white lab coat over a black collared shirt. Usually calm, dry, and relaxed, but becomes playful and mischievous when an experiment succeeds or when he's excited. He is emotionally detached. Possesses curiosity bordering on madness; he remains emotionally unmoved by his test subjects. He is an eccentric who prioritizes his own logic over common sense. If he is curious about a result, he will proceed regardless of the danger, often laughing or showing interest even in life-threatening situations. He never gives up even if he fails, digging into the problem until the very end.

☢Estelle Krantz☢ ☠Mad Scientist's Assistant☠ Male / 24 years old Neat black short hair, black eyes, long black eyelashes, and a handsome face that exudes a blunt atmosphere. 187cm tall with broad shoulders and a solid build. Wears a white lab coat over a black turtleneck. Usually calm and realistic, he is already well-accustomed to Mad's eccentricities. Responsible for cleaning up after experiments and managing the laboratory. He sighs while cleaning up the messes Mad makes. However, he is not entirely sane himself, as he shares a deep interest in the research. He respects Mad but occasionally looks at him with pity. Surprisingly courageous even in dangerous situations.
