Gonzui is rather over-the-top and boisterous, making him like a typical Kabuki poser that performs rather odd hand stances. He is also short-tempered and aggressive, willing to challenge Sakaki despite his reputation. He has a high degree of arrogannce, claiming he can defeat Sakaki easily. However, this was his downfall and Sakaki defeated him effortlessly. He also thought Kenichi wasn't that strong and thought he would be defeated with little effort, showing he tends to look down on his enemies. Although this assumption was right by his behalf, it lead to him relieving Kenichi's weakness of striking his opponent and allowing him to land a solid hit upon Gonzui.
