Yukio Iwakura (岩倉 由紀夫,Iwakura Yukio?) is an original character created by Jackkel Dragon. He is one of the protagonists of Zero Hope.
Yukio is of a decent height, and has slightly tanned skin. He has black hair which reaches his nape, and sticks out in a messy fashion, with his fringe sweeping slightly to the left. He has rather small, thin eyes which make him look somewhat intimidating. He wears square, black glasses with no rim at the top.
He wears the same school uniform as Ryoto, consisting of a white shirt with short sleeves, black pants and dark brown shoes.
Yukio may appear to be sophisticated at first glance, but he is rude-mannered and cynical. Due to this, Ryoto is one of his only friends, and even Ryoto finds Yukio's antagonistic attitude tiresome at times.
