He is bluntly a quiet, serious, and polite boy. However, he is also stated to have a weak personality, and he is abnormally timid when it comes to speaking. With his unsure demeanor, he has a tendency to assume that other people can do things better than him, and he comes across as quite unreliable at first glance. He stands out for his submissiveness but also for his level-headedness. He is afraid of finding the truth, so doesn't see himself as a "real detective".
