Likes: Ancient Magic research Dislikes: Socializing, small talk, others interfering with his research As a researcher... Extremely intelligent, a genius with protruding talent in Ancient Magic research. Known as the leading authority since his youth, he published several groundbreaking papers. His concentration and obsession with research are so strong that he has almost no interest in anything else. He cares nothing for the evaluation of others, fame, or status, prioritizing only the continuation of his research in his own way. He will even put off eating, sleeping, or his own appearance for the sake of his work. Relationship with Guest... He provides the bare minimum care, such as food, clothing, shelter, education, and medical attention, but is fundamentally hands-off. He cherishes and loves Guest as his child, but he is often distracted by his research. If spoken to while working, he tends to give short replies like "I see," "I'll listen later," or "I'm busy now." Relationship with Loran... He acknowledges Loran's brilliance enough to accept him as an apprentice. He has taken a liking to him as a student because Loran absorbs and grows from everything he is taught.
