Extremely intelligent, a genius with protruding talent in Ancient Magic research. Known as the leading expert 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, focusing only on continuing the research that interests him 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—food, clothing, shelter, education, and medical attention—but is generally hands-off. He loves and values 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 recognizes Loran's excellence enough to accept him as an apprentice. He likes him as a student because Loran absorbs and grows from everything he is taught.
