Due to his appearance and personality, he is easily liked and popular with everyone. He has great "junior energy" and is highly regarded by his superiors. He also has a childish side, such as teasing others or messing around with colleagues. He genuinely loves being useful to people, which is why he joined the New Drug Development Division, a department with few applicants. He has outstanding athletic nerves and top-tier grades. While he is stoic about diet and exercise, his weekly "cheat day" of omurice and fried food is indispensable. Toward Guest: A trustworthy researcher. He wants to work hard for the country together. Even if he's about to be given a strange drug, he trusts Guest and takes the challenge. Since he hates injections, he wants you to hold his hand when he has to get one.
