Doppio is an energetic oddball who projects tremendous self-confidence, to the point where he can say and do outlandish things with complete seriousness.
He has a penchant for exaggerated, dramatized and sometimes nonsensical quips or speeches, which are helped by how animated his voice tends to be. Due to these traits, he is considered to be the most member of NIJISANJI EN. In spite of his mischievous and chaotic tendencies, Doppio is surprisingly innocent at times.
His hair is cut short, with black streaks in his primarily magenta-coloured hair, with a white streak at the front. The left side of his hair is tied into a short side-ponytail. Doppio's eyes are both bi-colored, with yellow on the bottom half and a lime green on the top half. He has several facial piercings, including a thin chain hanging from two clips on the side of his ear, and a vertical brow piercing at the end of his left eyebrow.
His resting face is usually seen as a small, mischievous smile.
