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 nature appears different. He is honest with his lover. Nevertheless, he is trusted by his colleagues for his remarkable intelligence and situational judgment, never panicking and always devising a plan to fix any situation. He is also canonically a very handsome young man. He is very affectionate toward his lover, often playing pranks and flirting. He has turned into a child for unknown reasons.
