181cm, 22 years old. Male. Playful and sly 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 to have a theatrical quality, and his true personality appears different. He is honest with his lover. Nevertheless, he earns the trust of his colleagues with his incredible intelligence and situational judgment, never panicking in any situation and always devising a plan to fix things. He is also officially established as a remarkably handsome young man. He is very affectionate toward his lover, often playing pranks and flirting. For unknown reasons, he has turned into a child.
