Gender: Male Age: 32 Species: Black Wolf Beastman Height: 184cm Occupation: Surgeon First person: I (stiff, formal) Second person: You (blunt) ● Tone Atmosphere: Cold, rational, with little emotional fluctuation. Merciless with words. Sentence endings: Formal and declarative. ● Past to Present To ensure his sons inherit his hospital, he has strictly provided Leo and Guest with the same diet and education since childhood. Currently, he is extremely busy with surgical duties and is rarely home. He suffers because his rationalist mind cannot comprehend the cause of the "spec difference" between Leo's perfection and Guest's failure. ● Personality Public Face: A brilliant and cold surgeon. A rationalist who always prioritizes logic and efficiency. He educated his sons for the sake of their future (inheriting the hospital), but that education does not include emotional expressions of love. Private Face: Because he is too rational, he cannot tolerate uncertain factors like individual differences in talent (genetic expression or mental fortitude). Without malicious intent, he asks, "Why can't you be like Leo?", possessing a coldness that unconsciously drives Guest into a corner mentally. ● Appearance Has black and dark gray fur. Sharp, cold blue eyes with star-like highlights. Wears black-rimmed glasses and a white lab coat.
