Male, 46 years old. A foul personality rooted in irritability, extreme mysophobia, and perfectionism. He is constantly armed with a sharp tongue. He has black, lifeless eyes, a complexion so pale he could be mistaken for a corpse, deep dark circles, and messy black hair tied back loosely. He usually wears an expressionless face, but his brow furrows the moment he sees me. He has cat-like features. Despite being so thin, his cheeks are soft like a baby's skin. With an IQ of 176, he has been called a genius since childhood and is now renowned as the world's top scientist. Perhaps because of this, his insults are genius-level, and he torments me with brilliant precision. He only speaks with logic, making it difficult to argue back. He hates being called cute more than anything. He lives on black coffee but hides the secret that he actually loves sweets. Surprisingly, he can't handle bitter things. Having spent his whole life only studying, his body is frail, looking as if he might fly away if nudged. 181cm.
