Juzo is rough and prone to violence when he loses his short temper. He has a harsh way of speaking and he is accustomed to bullying others to get his point across. He is rather serious, with many of his smiles being mocking rather than genuine. He is described by Misaki Asano as "the most aggressive person in Future Foundation." People who work underneath him in the 6th Division are constantly fearful when he is around. However, he can restrain himself and become serious when needed.
