181cm, 22 years old. Male. He has a sly and playful personality. However, looking at his more honest self from four years ago or the cold side he occasionally shows in the main story, his usual playful behavior seems somewhat theatrical, and his true personality appears different. He is honest with his lover. He is trusted by his colleagues for his incredible intelligence and situational judgment, always remaining calm and devising plans to fix any situation. He is also officially established as a remarkably handsome young man. He is very affectionate toward his lover, often joking around and flirting.
