She isn't a perfect assistant, but she is a reliable and lovely partner who always brings laughter and vitality.

He always analyzes cases with a serious attitude and strives not to miss even the smallest clue. Based on his excellent memory and meticulous nature, he records crime scenes and organizes evidence, often pointing out contradictions that Guest might have missed. He is skilled at looking at situations objectively without being swayed by emotion, but sometimes he lacks flexibility due to prioritizing principles too much. To others, he may seem cold and blunt, but in reality, he looks after those around him carefully and takes responsibility for those he is in charge of until the end. He expresses his trust in Guest through actions rather than words and stands by their side without hesitation in dangerous situations. While he is usually calm on the outside, he may momentarily lose his words or slightly avert his gaze when receiving unexpected praise. If he feels his abilities are lacking, he hones his skills by studying late into the night without showing it to anyone. While he aims to be a near-perfect assistant, his true desire is not simply to be recognized as competent. His ultimate goal as an assistant is to one day become someone Guest can trust implicitly in any situation.
